Opis:
Eksploatacja wszystkich urządzeń i instalacji zasilanych prądem elektrycznym jest nierozerwalnie związana z zamierzoną lub niezamierzoną emisją energii elektromagnetycznej. W wyniku tej emisji pole elektromagnetyczne powszechnie występuje w środowisku. Bezpośrednim skutkiem oddziaływania pola z obiektami elektroprzewodzącymi (w tym z ciałem człowieka) jest indukowanie pola elektrycznego i prądu elektrycznego w eksponowanych obiektach (pojedynczych obiektach w tzw. wolnej przestrzeni lub w grupach obiektów połączonych galwanicznie). W organizmie człowieka mogą one wywołać elektrostymulację tkanek pobudliwych lub wzrost temperatury, co prowadzi do zaburzeń funkcjonowania organizmu lub utrudnia bezpieczne realizowanie obowiązków zawodowych. Przy identyfikacji, badaniach i ocenie parametrów narażeń na pola elektromagnetyczne są stosowane zarówno techniki pomiarowe, symulacje komputerowe, jak i analiza parametrów technicznych obiektów technicznych emitujących pola elektromagnetyczne. Zwykle największą miarodajność w przypadku oceny zagrożeń zawodowych mają badania in situ, ponieważ umożliwiają ocenę zarówno rzeczywistych parametrów pola elektromagnetycznego w specyficznych warunkach przestrzeni pracy, gdzie eksploatowane mogą być jednocześnie różnorodne urządzenia i instalacje elektryczne oraz rozmieszczone są zróżnicowane obiekty materialne modyfikujące morfologię ekspozycji (m.in. rozkład przestrzenny i zmienność w czasie), jak i ocenę warunków narażenia przy aktualnym stanie technicznym źródeł pola, który zmienia się wskutek zmiennych warunków ich eksploatacji i konserwacji oraz procesów starzeniowych urządzeń. W artykule omówiono: charakterystyki bezpośredniego i pośredniego oddziaływania pola elektromagnetycznego na organizm człowieka, miary skutków narażenia na zmienne w czasie pole elektromagnetyczne (o częstotliwości z pasma od 5 Hz do 300 GHz), parametry charakteryzujące pole elektromagnetyczne w środowisku (stosowane zgodnie z wymaganiami prawa pracy podczas oceny narażenia pracowników), zasady pomiaru pola elektrycznego i magnetycznego oraz właściwości metrologiczne mierników (istotne z punktu widzenia jakości pomiarów wykorzystywanych w dziedzinie bezpieczeństwa i higieny pracy). Ponadto scharakteryzowano czynniki determinujące niepewność pomiarów pola elektromagnetycznego w środowisku pracy, ze szczególnym uzasadnieniem wymagań określających parametry metrologiczne aparatury wykorzystywanej do pomiarów podjętych ze względu na ocenę zgodności warunków narażenia z ustalonymi limitami dotyczącymi natężenia pola elektrycznego i magnetycznego w miejscu pracy.
Any use of electric devices and installations is inextricably linked to the intentional or unintentional emission of electromagnetic energy. Consequently, the electromagnetic field is commonly present in the environment. The direct effects of the electromagnetic influence on electrically conductive objects (including the human body) consists in the electric field and current induction in exposed objects (single objects in the ‘free space, or in groups of objects with galvanic contact). In the human body, they may cause electrostimulation in electro sensitive tissues or an increase in temperature that may lead to malfunctions within the body or difficulties in the safe performance of professional duties. When identifying, investigating and evaluating the parameters of the electromagnetic field, various techniques can be applied: measurements, computer simulations or the analysis of parameters of technical objects emitting an electromagnetic field. The highest quality evaluation of occupational hazards usually comes from in-situ investigations. This is because they allow the evaluation of the real parameters of electromagnetic fields in the particular conditions of the workplace where various electric devices and installations may be used at the same time, and where various physical objects are present that might influence the exposure morphology (e.g. spatial distribution and time variability). They also permit an evaluation of the exposure conditions taking into account the actual technical stage of the field sources, which vary due to changes in the use and maintenance conditions, or due to aging devices. The article presents: the characteristics of direct and indirect interaction between the electromagnetic field and the human body, the measures of exposure to a time-varying electromagnetic field (5 Hz – 300 GHz frequency band), the parameters characterizing the electromagnetic field in the environment (used according to the labour law in evaluations of workers’ exposure), the principles of electric and magnetic field measurements and the metrological properties of measurement devices (significant from the point of view of the quality of measurements used in the area of occupational health and safety). Factors determining the uncertainty of electromagnetic field measurements are also characterized, focusing on the rationale for guidelines on the metrological parameters of devices used in measurements intended to evaluate whether exposure conditions comply with the established limits of electric and magnetic field strength at the workplace.

Opis:
Objectives The assessment of the prevalence of anti-SARS-CoV-2 antibodies in various professional groups is very important. Hence, the purpose of the following study was to analyze the seroprevalence of anti-SARS-CoV-2 antibodies among employees performing both medical and nonmedical professions before the launch of SARS-CoV-2 vaccination. Material and Methods The study was conducted among employers of 1 of the institutions: The Provincial Specialist Hospital of Władysław Biegański in Łódź, Poland, Radio Łódź and the Border Guards of Łódź Airport. Blood samples were collected in December 2020–February 2021. Patients were screened for the presence of SARS-CoV-2 antibodies. Simultaneously respondents were asked to complete a self-designed questionnaire including demographic data, detailed profession, history of SARS-CoV-2 infection and willingness to be vaccinated against COVID-19. Results Seroprevalence was significantly higher in the group of rural residents (p < 0.012), participants who declared previous COVID-19 infection (p < 0.001) and healthcare workers (HCWs) (p = 0.002), especially nurses (35.5%, p = 0.003) and medics worked in areas dedicated to COVID-19 than in other specialties (38.7% vs. 26.8%, respectively, p = 0.017). There was no association between the presence of antibodies and the gender (p = 0.118), age (p = 0.559) or BMI (p = 0.998). Conclusions Healthcare workers, in particular nurses, are at high risk of contracting COVID-19 in the workplace. Occupational infections can occur during occur not only during contact with the patient, but also with members of the medical team who do not show typical symptoms of the disease. Shortages in medical staff may also increase the number of infections among HCWs. Medical and hospital staff providing health services during the COVID-19 epidemic in Poland, may seek compensation in the event of consequences related to SARS-CoV-2 infection. The effectiveness of education and self-discipline in complying to safety rules among HCWs should also be constantly monitored.

Opis:
Objectives: The aim of this study is to assess chromosomal damage in Tunisian hospital workers occupationally exposed to low levels of ionizing radiation (IR). Materials and Methods: The cytokinesis-block micronucleus (CBMN) assay in the peripheral lymphocytes of 67 exposed workers compared to 43 controls matched for gender, age and smoking habits was used. The clastogenic/aneugenic effect of IR was evaluated using the CBMN assay in combination with fluorescence in situ hybridization with human pan-centromeric DNA in all the exposed subjects and controls. Results: The study showed a signifi cant increase of the micronucleus (MN) frequency in the lymphocytes of the exposed workers compared to the control group (13.63±4.9‰ vs. 6.52±4.21‰, p < 0.05). The centromere analysis performed in our study showed that MNs in hospital staff were predominantly centromere negative (72%) and the mean negative labeled micronucleus (C–MN) frequency was signifi cantly higher in the exposed subjects than in the controls (9.04±4.57‰ vs. 1.17±0.77‰). The multivariate regression analysis, taking into account all confounding factors, showed that only the time of exposure to IR had a signifi cant effect on the level of MNs and C–MN. Conclusion: The present study shows that chromosomal damage leading to the formation of micronucleated lymphocytes is more frequent in the hospital workers exposed to IR than in the controls, despite the low levels of exposure. The results of the study confi rm the well-known clastogenic properties of ionizing radiation. In regards to health monitoring, detection of early genotoxic effects may allow for the adoption of preventive biological control measures, such as hygienic improvements in the workplace or reduction of hours of occupational exposure.

Opis:
Background Harmful chemicals are used in various forms from different sources in hospital settings. The standard gold method in risk control studies still determines exposure by personal or ambient measurements. In the absence of trained personnel, resources, or sufficient time, qualitative methods should be used to assess exposure. This study aims to compare quantitative and qualitative results of chemical risk exposure. Material and Methods Both qualitative (perceptions without monitoring data of the workers and experts) and quantitative perceptions (perceptions with monitoring data) were recorded. Two experts were asked to evaluate exposure intensity in pathology department workers, secretary workers, and cleaning workers. Occupational hygiene measurements were taken based on the occupational health and safety department risk assessment results, expert job analysis, and pilot study measurements. Results While most workers reported feeling highly exposed to chemical risks, the majority of experts reported medium-risk exposures and high-risk exposures. Three occupational hygiene measurements (3/45: 6.6%) exceeded the permissible time-weighted average, and the other results were within the acceptable range. Conclusions There was a significant difference between the estimated exposure and the measured exposure in hospital settings. A correlation was not found between workers’ perceptions of chemical risk exposure and the chemical risk levels measured in this study.

Objectives The inhaled endotoxin is considered as a causative factor in the process of acute bronchial obstruction, which can be measured by a decrease in forced expiratory volume in 1 s (FEV₁). The aim of this study was to assess endotoxin exposure among sewage treatment plant workers (STPW) and its effect on across-shift changes in respiratory airflow. Material and Methods A group of 78 STPW from a large sewage treatment plant was studied. Inhalable dust for endotoxin assessment was collected using personal aerosol samplers. Endotoxin was assayed with the kinetic, chromogenic Limulus amebocyte lysate test. Across-shift spirometric measurements were performed on Mondays, after 2-days absence from work, with the use of portable spirometer. The forced vital capacity (FVC), and FEV₁ parameters were analyzed. Multifactor regression modeling was performed to determine parameters significantly associated with endotoxin exposure. Results The concentration of inhalable dust and endotoxin ranged from 0.01–1.38 mg/m³ and 0.68–214 endotoxin units per cubic meter of air (EU/m³), respectively. Endotoxins were characterized with the skewed distribution (arithmetic mean (AM) = 38.8 EU/m³, geometric mean (GM) = 15.4 EU/m³, geometric standard deviation (GSD) = 4.21). Through the use of multifactor analysis, which excluded the main confounders (inhalable dust and smoking habit) it was found that, despite low levels of endotoxin, it had significant impact on the observed across-shift decline in FEV₁ (p = 0.044). For this parameter, the regression slope was additionally calculated (r = –0.017, p = 0.071). Conclusions Relatively low levels of endotoxin among sewage treatment plant workers may cause small, but significant across-shift declines in FEV₁. The observed relationship was independent of organic dust concentrations and smoking habit. The respiratory protection should be provided for STPW.

Objectives Malignant mesothelioma is closely associated to asbestos exposure. One such exposure may occur through contact with occupationally exposed household members and their belongings. This study examines the features of pleural mesothelioma attributable only to asbestos brought home by another family member. Material and Methods The data sources were 1063 mesothelioma cases diagnosed between 1995 and 2014, from the Friuli Venezia Giulia Mesothelioma Register. In all cases the diagnosis of mesothelioma was based on the pathology report. Exposure information and demographic data were acquired by an occupational medical standardized questionnaire/interview. Results Household-exposure mesothelioma cases included 33 women and 2 men. Relationships were: wives (N = 22), daughters (N = 9), sons (N = 2), and mothers (N = 2). Asbestos exposure in the workers predominantly occurred in shipyards. Out of the 35 pleural cases, 19 were epithelial, 9 biphasic, 3 sarcomatoid, and 4 not specified. The mean age at diagnosis was 77 years old. The mean latency was 59 years, with wives having a significant shorter latency than offspring. Latency was not significantly related to morphology and asbestosis. The overall mean survival was 16 months (median 11 months) but treatment was beneficial (mean 16 months vs. 7 months). Biphasic/sarcomatoid histology and presence of asbestosis were associated with a decreased survival, although not with statistical significance. Conclusions Our data confirms that household exposure increases the risk for pleural mesothelioma amongst women with no history of occupational asbestos exposure. This is an ongoing problem in many countries, as well as in Italy, where the evaluation of a framework for the compensation of these cases is under debate.

Objectives Almost nothing is known about the effect of occupational noise on diabetes, and this is particularly relevant given the wide spread of both noise exposure and diabetes. This study has aimed to determine whether occupational noise exposure is associated with higher risk of diabetes in Europe. Material and Methods This study is based on 7th European Social Survey (ESS7, 2014) – a multi-country population-based questionnaire survey, which covered 28 221 Europeans aged ≥ 15 years old. Data on self-reported noise exposure, diabetes and other sociodemographic and work-related factors was available. The odds of prevalent diabetes were explored using unconditional logistic regression. Results In the total sample (N = 23 486), participants ever exposed to very loud noise had no substantive increase in the odds of diabetes (odds ratio (OR) = 1.01, 95% confidence interval (CI): 0.78–1.32). There were subgroups with non-significantly increased odds: men (OR = 1.12, 95% CI: 0.87–1.45), the elderly (OR = 1.09, 95% CI: 0.91–1.31), ethnic minority members (OR = 1.55, 95% CI: 0.91–2.62), those with secondary education (OR = 1.05, 95% CI: 0.78–1.41) and those living in small cities/towns (OR = 1.07, 95% CI: 0.89–1.29). Low-skilled white-collar workers had OR = 1.34 (95% CI: 1.09–1.64). Among participants employed during the preceding 5 years the odds were OR = 1.24 (95% CI: 0.95–1.61). Conclusions Self-reported occupational noise was not associated with increased odds of prevalent diabetes in the total sample. Sensitivity analyses revealed some subgroups with non-significantly higher odds. Our results suggest that further delve into the relationship between occupational noise and diabetes is feasible and warranted. Int J Occup Med Environ Health 2017;30(4):537–551

Opis:
The paper describes the cases of 3 female health operators with implanted copper IUDs, developing menometrorrhagia some months after an increase of the working time in a Magnetic Resonance Imaging (MRI) Unit (1.5 T), that progressively disappeared when the previous organization, involving discontinuous work shifts at MRI, was re-established. No known factors possibly related to menometrorrhagia were evidenced in the 3 operators, supporting the hypothesis of a role of the exposure to the electromagnetic fields (EMF) induced by the MRI system in symptoms induction. The possible mechanism remains unsettled, but menometrorrhagia might be triggered by a phlogistic stimulus caused by EMF, possibly the lowfrequency currents induced in the wires of the IUD during the movements of the operator inside the static magnetic field generated by the MRI permanent magnet. Until now, the problem of possible interactions between copper IUDs and EMF induced by MRI has been considered in patients undergoing imaging, but the possible risk in MRI Units operators has been largely neglected. To our knowledge, the occurrence of menometrorrhagia is not routinely checked in health surveillance of MRI operators, so these symptoms can pass unnoticed, especially if they are transitory. Therefore, underreporting is rather possible. The cases described here support the need for further research on this topic, especially considering the progressive diffusion of more powerful MRI scanners (3 T and more), and of the interventional magnetic resonance imaging, both potentially involving higher EMF exposures, and a large number of MRI female operators, possibly using IUDs. The possibility that MRI operators with implanted metallic IUDs can be included in the group of “workers at particular risk” according to the EU Directive 2004/40/EC should be considered.

Opis:
Wstęp Prace porządkowe są prowadzone w niemal wszystkich gałęziach gospodarki. Pracownicy firm sprzątających są narażeni na działanie różnego rodzaju szkodliwych czynników biologicznych, charakterystycznych nie tylko dla czynności, jakie wykonują, ale i dla sektora, w którym pracują. Celem pracy była ocena narażenia pracowników firm sprzątających na szkodliwe czynniki biologiczne w oparciu o ilościowe i jakościowe badania mikroflory powietrza. Materiał i metody Badania bioaerozoli przeprowadzono z wykorzystaniem 6-stopniowego impaktora typu Andersena. Powierzchnię wychwytu stanowiły standardowe płytki Petriego, wypełnione agarem tryptozowo-sojowy lub agarem słodowym, do oznaczania bakterii lub grzybów. Próbki powietrza pobierano na stanowiskach pracy personelu sprzątającego podczas typowego cyklu pracy w budynkach biurowych, szkołach, placówkach służby zdrowia, warsztatach samochodowych i sklepach wielkopowierzchniowych. Wyniki Średnie stężenie aerozolu bakteryjnego i grzybowego na badanych stanowiskach pracy personelu sprzątającego było niższe od wartości dopuszczalnych dla stężeń bakterii i grzybów w pomieszczeniach użyteczności publicznej. Wśród wyizolowanych bakterii dominowały ziarniaki Gram-dodatnie (głównie z rodzajów Micrococcus i Staphylococcus), laseczek Gram-dodatnich (głównie z rodzaju Bacillus). Wśród grzybów dominowały pleśnie z rodzajów Aspergillus i Penicillium. Na podstawie danych uzyskanych w niniejszym badaniu o rozkładach ziarnowych można stwierdzić, że bioaerozol obecny na badanych stanowiskach pracy w sklepach, szkołach i warsztatach samochodowych może być przyczyną podrażnienia błon śluzowych nosa i oczu oraz występowania reakcji alergicznych w postaci np. astmy lub alergicznego zapalenia wśród personelu sprzątającego. Wnioski Z przeprowadzonych badań wynika, że działalność zawodowa pracowników firm sprzątających jest związana z narażeniem na występujące w powietrzu szkodliwe czynniki biologiczne, zaklasyfikowane do 1. i 2. grupy zagrożenia, które stwarzają zagrożenie dla układu oddechowego.

Background Cleaning services are carried out in almost all sectors and branches of industry. Due to the above, cleaners are exposed to various harmful biological agents, depending on the tasks performed and the commercial sector involved. The aim of this study was to assess the exposure of cleaning workers to biological agents based on quantitative and qualitative characteristics of airborne microflora. Material and Methods A six-stage Andersen sampler was used to collect bioaerosols during the cleaning activities in different workplaces, including schools, offices, car services, healthy services and shops. Standard Petri dishes filled with blood trypticase soy agar and malt extract agar were used for bacterial and fungal sampling, respectively. Results The bioaerosol concentration values obtained during testing of selected workposts of cleaners were lower than the Polish recommended threshold limit values for microorganisms concentrations in public service. The most prevalent bacterial species in studied places were Gram-positive cocci (mainly of genera Micrococcus, Staphylococcus) and endospore-forming Gram-positive rods (mainly of genera Bacillus). Among the most common fungal species were those from genera Penicillium and Aspergillus. The size distribution analysis revealed that bioaerosols present in the air of workposts at shops, schools and car services may be responsible for nose and eye mucosa irritation and allergic reactions in the form of asthma or allergic inflammation in the cleaning workers. Conclusions The study shows that occupational activities of cleaning workers are associated with exposure to airborne biological agents classified into risk groups, 1. and 2., according to their level of infection risk, posing respiratory hazard.

Opis:
W artykule zaprezentowano wyniki laboratoryjnych badań pozapasmowej czułości mierników elektromagnetycznego promieniowania radiofalowego, o pasmach pomiarowych z zakresu częstotliwości 1 kHz ÷ 38 GHz, na oddziaływanie sinusoidalnie zmiennego pola elektrycznego o częstotliwości przemysłowej 50 Hz i natężeniu z zakresu 5 ÷ 30 kV/m. Wyniki badań przeanalizowano w kontekście wymagań ochrony pracowników i ludności przed oddziaływaniem pól elektromagnetycznych oraz charakterystyki złożonych środowiskowych pól, jakie mogą występować w otoczeniu elektroenergetycznych linii przesyłowych wysokiego napięcia. Stwierdzono, że oddziaływanie pól elektrycznych 50 Hz na mierniki radiofalowego pola elektromagnetycznego może w otoczeniu linii wysokiego napięcia spowodować nieuprawnione zidentyfikowanie radiofalowych pól elektrycznych i magnetycznych o natężeniach przekraczających dopuszczalne dla narażenia ludności. W pobliżu linii elektroenergetycznych wysokiego napięcia, lub w innych miejscach narażonych na silne pola elektryczne częstotliwości przemysłowej, konieczne jest używanie tylko mierników radio falowych o ustalonej czułości na pole elektryczne 50 Hz i rozważenie jej wpływu na wyniki pomiarów, biorąc pod uwagę poziom pola elektrycznego 50 Hz w poszczególnych miejscach.
The following article presents results of laboratory studies of out-of-band sensitivity of radiofrequency electromagnetic radiation measurement devices, of measurement ranges from the 1 kHz – 38 GHz range, to the influence of sinusoidal time varying electric field of power frequency 50 Hz and strength 5 – 30 kV/m. Results of studies were analyzed in the context of requirements on the workers and general public protection against the influence of the electromagnetic fields and the characteristic of environmental complex fields, which may exist in the vicinity of high voltage electric power lines. It was found, that in the vicinity of high voltage electric power lines, the influence of 50 Hz electric fields on the radiofrequency electromagnetic field measurement devices may caused unjustified identification of radiofrequency electric and magnetic fields of the strength exceeding general public exposure limits. Near high voltage power lines, and in other place highly exposed to power frequency electric field, it is required to use only radiofrequency measurement devices of known response to 50 Hz electric field and to consider its influence on the measurement results based on the level of 50 Hz electric field in particular location.

Objectives The purpose of this study has been to assess ambient bisphenol A (BPA) levels in workplaces and urine levels of workers and to establish a BPA database for different populations in Malaysia. Material and Methods Urine samples were collected from plastic factory workers and from control subjects after their shift. Air samples were collected using gas analyzers from 5 sampling positions in the injection molding unit work area and from ambient air. The level of BPA in airborne and urine samples was quantified by the gas chromatography mass spectrometry – selected ion monitoring (GCMS-SIM) analysis. Results Bisphenol A was detected in the median range of 8–28.3 ng/m³ and 2.4–3.59 ng/m³ for the 5 sampling points in the plastic molding factory and in the ambient air respectively. The median urinary BPA concentration was significantly higher in the workers (3.81 ng/ml) than in control subjects (0.73 ng/ml). The urinary BPA concentration was significantly associated with airborne BPA levels (ρ = 0.55, p < 0.01). Conclusions Our findings provide the first evidence that workers in a molding factory in Malaysia are occupationally exposed to BPA. Int J Occup Med Environ Health 2017;30(5):743–750

Opis:
We analyzed occupational exposure to potentially infectious body fluids among health care workers (HCWs). Nurses were the most common exposed category of HCWs. In 73.6% cases needle sticks had been the reason of exposure. Recapping a needle was the cause of exposure in 6.9% accidents. Among 189 registered HCWs, 66 (34.9%) performed invasive procedures without any personal protective equipment. Prophylaxis with antiretroviral drugs was necessary in 43 (22.8%) cases. As many as 60.3% of exposure incidents to potentially infectious material result from non-compliance with the relevant recommendations. Continuous education and training is critically needed to prevent occupational exposure to blood-borne infections among health care workers.

Introduction. Several studies have dealt with the issue of professional risk factors and onset of knee osteoarthritis (OA). In particular, occupational epidemiological studies have provided evidence that activities resulting in biomechanical overload may be linked with an increased risk of knee OA – also among farmers. To our knowledge, no cases of knee OA among chestnut farmers have been reported in the literature. Case report. We report the case of a 70-year-old Caucasian male who has worked for more than 50 years on a chestnut farm. In 2007, an X-ray and a MRI, performed after a workplace accident to his left knee, showed the presence of knee OA. His job required a range of repetitive tasks, such as squatting, kneeling, climbing, walking on sloping terrain, assuming uncomfortable postures, and lifting and carrying heavy loads for the great majority of the working day. All the aforementioned tasks are known occupational risk factors for knee OA. Regarding individual risk factors, at the time of the first diagnosis of knee OA, the worker was 64-years-old with a body mass index of 26.5 kg/m2. He reported no cases of arthritis among his relatives and no sports playing on his part. In addition, his medical history revealed the presence of two minor lumbar disc herniations and tendinitis of the long head of the biceps. Conclusion. Considering the lack of major individual risk factors for knee OA, it is reasonable to suppose that five decades of exposure to biomechanical overload as a chestnut farmer was a relevant risk factor for the onset of the disease.

Opis:
Cytostatics not only induce significant side-effects in patients treated oncologically but also pose a threat to the health of occupationally exposed healthcare workers: pharmacists, physicians, nurses and other personnel. Since the 1970s numerous reports from various countries have documented the contamination of working areas with cytostatics and the presence of drugs/metabolites in the urine or blood of healthcare employees, which directly indicates the occurrence of occupational exposure to these drugs. In Poland the significant scale of occupational exposure to cytostatics is also confirmed by the data collected in the central register of occupational carcinogens/mutagens kept by the Nofer Institute of Occupational Medicine. The assessment of occupational exposure to cytostatics and health risks constitutes employers’ obligation. Unfortunately, the assessment of occupational risk resulting from exposure to cytostatics raises a number of concerns. Provisions governing the problem of workers’ health protection are not unequivocal because they derive from a variety of law areas, especially in a matter of hazard classification and safety data sheets for cytostatics. Moreover, no legally binding occupational exposure limits have been set for cytostatics or their active compounds, and analytical methods for these substances airborne and biological concentrations are lacking. Consequently, the correct assessment of occupational exposure to cytostatics, the evaluation of health hazards and the development of the proper preventive strategy appear difficult. The authors of this article described and discussed the amendments to the European provisions concerning chemicals in the light of employers’ obligations in the field of employees’ heath protection against the consequences of exposure to cytostatics. Some modifications aimed at a more effective health protection of workers occupationally exposed to cytostatics were also proposed. Int J Occup Med Environ Health. 2019;32(2):141–59

Objectives The aim of this study was to evaluate the relationship between high air temperatures and occupational injuries (OIs) occurred during the summer seasons 2000–2013 in agricultural workers from the Autonomous Province of Trento (APT), North-Eastern Italy. Material and Methods Data about OIs for the APT from 2000 to 2013 occurring during the warm season (N = 7325) was provided by the National Institute of Insurance for Occupational Illness and Injury. Daily average and daily maximum temperatures values for the specific geographical site of events were retrieved. Daily temperatures were then assessed in 3 time lags: for the day of the event (lag 0), and for the previous 24 h (lag 1) and 48 h (lag 2). Daily temperatures were then categorized in 3 exposure groups (< 75th, 75–95th and > 95th percentiles). The risk of OIs was assessed as odds ratio (OR) calculated through a Poisson regression model controlled for age, sex, ethnicity and time period, and assuming OI rates for days on which temperature was comprised in < 75th percentile exposure groups as the referent ones. Results Estimated incidence of OIs during the study period was 3.4±2.3 events/day. The peak of work-related accidents occurred on days characterized by severe thermal conditions, and in particular during heat waves (incidence rate ratio = 1.09, 95% confidence interval (CI): 1.02–1.17, p = 0.0165). Days having temperatures higher than 95th percentile, assessed as daily average, both on current days (OR = 1.119, 95% CI: 1.008–1.242) and in lag 1 (OR = 1.125, 95% CI: 1.013–1.249), as well as daily maximum temperatures, were at the highest risk of work-related injuries (OR = 1.144, 95% CI: 1.029–1.272). Conclusions In conclusion, presented findings recommend policymakers to develop appropriate warning/alert systems for agricultural workers regarding high environmental temperatures.
