ObjectivesThe aim of this study is to conduct a quantitative assessment of the risk related to occupational exposure to wood dust and the occurrence of sinonasal epithelial cancer (SNEC) by histotype, depending on the duration of exposure, using mathematical models.Material and MethodsThe relationship between the occurrence of SNEC by histotype (adenocarcinoma [AR] and tumors of other histotypes) and exposure to wood dust has been studied using the values of the odds ratios for individual periods of employment involving exposure to wood dust, and their 95% confidence intervals. The dose-response curves were constructed (more precisely, the duration of exposure-response curves). The author attempted to match the linear, quadratic or exponential models.ResultsIn all SNEC cases, there is a relationship between the duration of occupational exposure to wood dust and the relative risk of developing cancer. The estimated relative risk of developing AR after 35 years of exposure to wood dust is about 300, and the estimated risk of developing SNEC is 50, compared to non-exposed people for whom the relative risk is equal to 1. However, the relative risk of developing other types of cancer is <20, also in comparison with non-exposed people.ConclusionsThe author has identified a relationship between the duration of occupational exposure to wood dust and the relative risk of developing cancer in all SNEC cases.

Background The respiratory system is the most vulnerable system in the cement industry. This study was conducted to determine the effects of occupational exposure to cement dust on the respiratory system more thoroughly. Material and Methods In this cross sectional study an interviewer-administered questionnaire on socio-demographic characteristics and respiratory symptoms was completed and pulmonary function tests were carried out on 100 exposed and 120 non-exposed workers at the cement factory in Mashhad, Iran. The data was statistically analyzed by SPSS 16. Results The mean of age and work duration in the exposed group was 37.5±6.3 and 10.7±5.4 years compared with the non-exposed group that was 36.1±7.1 and 10.1±5.7 years, respectively. Levels of exposure to inhalable cement dust in the exposed group were 23.13 mg/m³ (higher than national occupational exposure limits for such particles). Among the exposed group, respiratory symptoms as cough (6% vs. 0.8% of the non-exposed) and sputum (7% vs. 0.8% of the nonexposed) were significantly more prevalent (p < 0.05). Forced expiratory flow 25–75% (FEF25–75%) was significantly lower in the exposed workers compared with non-exposed ones (p < 0.05). Also forced expiratory volume in 1 s / forced vital capacity (FEV₁/FVC) and FEF25–75% had a reverse correlation with the length of employment (p = 0.000 and p = 0.003, respectively). Conclusions The findings of this study showed that occupational exposure to cement dust could be a significant factor of respiratory system dysfunction. Strict implementation of a respiratory protection program is recommended in cement industries. Med Pr 2015;66(4):471–477
Wstęp Układ oddechowy jest tym najbardziej narażonym w przypadku pracy w przemyśle cementowym. Poniższe badanie miało na celu precyzyjne określenie wpływu na układ oddechowy narażenia zawodowego na pył cementowy. Materiał i metody W ramach analizy przekrojowej 100 narażonych oraz 120 nienarażonych na pył pracowników fabryki cementu w Mashhad w Iranie wypełniło kwestionariusz na temat cech społeczno-demograficznych oraz objawów oddechowych, a także poddało się testom wydolności płuc. Otrzymane dane zostały przeanalizowane statystycznie za pomocą SPSS 16. Wyniki Średnia wieku oraz czas zatrudnienia dla grupy badanej wyniosły odpowiednio 37,5±6,3 roku oraz 10,7±5,4 roku, a dla grupy porównawczej 36,1±7,1 roku oraz 10,1±5,7 roku. Poziom narażenia na działanie wdychanego pyłu cementowego w grupie badanej wyniósł 23,13 mg/m³ i przekraczał dozwoloną krajową normę narażenia zawodowego na te cząstki. W grupie badanej takie objawy oddechowe, jak kaszel (6% vs 0,8% w grupie porównawczej) i plwocina (7% vs 0,8%) znacznie przeważały nad innymi (p < 0,05). Wymuszony przepływ wydechowy 25–75% (FEF25–75%) odnotowano na znacznie niższym poziomie w przypadku narażonych pracowników w porównaniu do tych nienarażonych (p < 0,05). Także stosunek natężonej objętości wydechowej pierwszosekundowej do natężonej pojemności życiowej (FEV₁/FVC) oraz FEF25–75% wskazywały na odwrotną korelację z długością zatrudnienia (odpowiednio: p = 0,000 i p = 0,003). Wnioski Narażenie zawodowe na pył cementowy może być ważnym czynnikiem powodującym dysfunkcję układu oddechowego. Ścisłe przestrzeganie programu ochrony układu oddechowego jest zalecane w przemyśle cementowym. Med. Pr. 2015;66(4):471–477

Case description. Five workers (2 males and 3 females) employed in a furniture factory located in eastern Poland developed hypersensitivity pneumonitis (HP) after the pine wood used for furniture production was replaced by birch wood. All of them reported onset of respiratory and general symptoms (cough, shortness of breath, general malaise) after inhalation exposure to birch dust, showed crackles at auscultation, ground-glass attenuations in HRCT examination, and lymphocytosis in the BAL examination. The diagnosis of acute HP was set in 4 persons and the diagnosis of subacute HP in one. Identification of specific allergen. Samples of birch wood associated with evoking disease symptoms were subjected to microbiological analysis with the conventional and molecular methods. Two bacterial isolates were found to occur in large quantities (of the order 108 CFU/g) in examined samples: Gram-negative bacterium of the species Pantoea agglomerans and a non-filamentous Gram-positive actinobacterium of the species Microbacterium barkeri. In the test for inhibition of leukocyte migration, 4 out of 5 examined patients showed a positive reaction in the presence of P. agglomerans and 2 in the presence of M. barkeri. Only one person showed the presence of precipitins to P. agglomerans and none to M. barkeri. In the inhalation challenge, which is the most relevant allergological test in the HP diagnostics, all patients reacted positively to P. agglomerans and only one to M. barkeri. The results indicate that P. agglomerans developing in birch wood was the main agent causing HP in the workers exposed to the inhalation of dust from this wood, while the etiologic role of M. barkeri is probably secondary. Conclusion. The results demonstrate that apart from fungi and filamentous actinobacteria, regarded until recently as causative agents of HP in woodworkers, Gram-negative bacteria and non-filamentous actinobacteria may also elicit disease symptoms in the workers processing wood infected with large amounts of these microorganisms. The results obtained also seem to indicate that cellular-mediated reactions are more significant for causing disease symptoms compared to those that are precipitin-mediated.

Introduction. Workers of pellet production facilities (WPPF) are exposed to high concentrations of wood dust and microbial pollutants. Such stimulation may lead to numerous allergic and toxic reactions, infections, and other non-specific syndromes. Objective. To check the influence of individual traits of workers and characteristic features / factors of their living and working environments on the probability of adverse outcomes’ appearance. Materials and Method. The questionnaire study assessing adverse health effects resulting from individual exposure was conducted among 28 workers of 10 Polish WPPF. The logistic regression (for dichotomous variables) was used to determine the appearance probability (given as odds ratio) of adverse symptoms or diseases. Results and Conclusions. WPPF workers may have an increased risk of developing work-related adverse health outcomes. Both the individual traits and environmental exposure factors significantly influence the probability of their occurrence.

Baza wiedzy o zagrożeniach chemicznych i pyłowych Chem- Pył, została opracowana w Zakładzie Zagrożeń Chemicznych, Pyłowych i Biologicznych Centralnego Instytutu Ochrony Pracy - Państwowego Instytutu Badawczego. Celem tej bazy jest stworzenie użytecznego narzędzia wspomagającego zadania związane z oceną narażenia i ryzyka zawodowego spowodowanego występowaniem czynników chemicznych i pyłowych na stanowiskach pracy, zarówno dla specjalistów zarządzających bezpieczeństwem i higieną pracy w przedsiębiorstwach, jak również pracodawców i pracowników tych zakładów. W bazie ChemPył, dostępnej na stronach portalu internetowego CIOP-PIB, zgromadzone są w jednym miejscu najbardziej przydatne materiały z zakresu narażenia na czynniki chemiczne i pyły w środowisku pracy. Przygotowano zbiór informacji na temat substancji chemicznych o ustalonych wartościach normatywów higienicznych, metod ich oznaczania na stanowiskach pracy, jak również ich właściwości fizykochemicznych, toksykologicznych, czy informacji z zakresu pierwszej pomocy. Nowym elementem bazy jest także zbiór praktycznych informacji dotyczących narażenia zawodowego na szkodliwe substancje chemiczne, wyników badań jakościowych i ilościowych tych substancji na przykładowych stanowiskach pracy lub w przykładowych procesach technologicznych z różnych działów gospodarki oraz oceny związanego z nimi ryzyka zawodowego, tzw. "Baza wyników pomiarów i oceny ryzyka".
The ChemPył chemical and dust risk knowledge base has been developed in the Department of Chemical, Dust and Biological Risks of the Central Institute for Labour Protection - National Research Institute (CIOP-PIB). The purpose of the base is to create a useful tool for assisting the assessment of exposure and occupational risk caused by chemical and dust agents in working environments, both for work health and safety management specialists in enterprises and for employers and employees of the enterprises. The ChemPył base, available at the CIOP-PIB website, gathers the most useful materials regarding exposure to chemical agents and dust in the occupational environment. A set of information on chemical substances with established hygienic standards, methods for measuring them at workplaces, and their physical and chemical, as well as toxicological properties or first aid information has been prepared there. A new item of the base includes also a set of practical information on occupational exposure to harmful substances, the results of qualitative and quantitative tests for the selected instances of workplaces or in selected technological processes from various economic sectors and the assessment of related occupational risk, the so-called "Database of risk assessment and test results".

Objectives: The study was aimed at assessment of exposure to endotoxins, (1→3)-β-D-glucans and mite, cockroach, cat, dog allergens present in settled dust in premises of children as agents which may be significantly correlated with the occurrence of allergic symptoms and diseases in children. Materials and Methods: The study covered 50 homes of one- or two-year-old children in Poland. Samples of settled dust were taken from the floor and the child's bed. The levels of (1→3)-β-D-glucans (floor), endotoxins (floor) and allergens of mite, cat, dog and cockroach (floor and bed) were analyzed. Results: Average geometric concentrations (geometric standard deviation) of endotoxins, (1→3)-β-D-glucans, Der p1, Fel d1, Can f1 and Bla g1 in children homes were on the floor 42 166.0 EU/g (3.2), 20 478.4 ng/g (2.38), 93.9 ng/g (6.58), 119.8 ng/g (13.0), 288.9 ng/g (3.4), 0.72 U/g (4.4) and in their beds (only allergens) 597.8 ng/g (14.2), 54.1 ng/g (4.4), 158.6 ng/g (3.1) 0.6 U/g (2.9), respectively. When the floor was covered with the carpet, higher concentrations of endotoxins, (1→3)-β-D-glucans and allergens (each type) were found in the settled dust (p < 0.05). The trend was opposite in case of allergens (except dog) analyzed from bed dust and significantly higher concentrations were found in the rooms with smooth floor (p < 0.05). Conclusions: Among the analyzed factors only the type of floor significantly modified both the level of biological indicators and allergens. The results of this study could be the base for verifying a hypothesis that carpeting may have a protective role against high levels of cockroach, dog and cat allergens.

Objectives. The airborne contaminant exposure levels experienced by poultry farmers have raised concerns about the possible health hazards associated with them. Thus, a longitudinal project was instituted in France to monitor these exposures in poultry workers and to evaluate the long-term effect on health. Method. Sixty-three workers in two different poultry housing systems were included (33 from floor-based systems and 30 from cage-based systems). Personal dust concentrations (over 2 days) and activity patterns (over 14 days) were collected and then modeled to obtain average long-term estimates. Health data were collected by questionnaire. Results. The mean daily time spent in the cage system was more than 2 hours longer than in the floor system. Two main common tasks accounted for ~70% of this time. Dust concentrations were higher in the floor system than in the cage system. The concentrations for the 14 days of known activity patterns estimated using the statistical model agreed well with the measured values. Several chronic respiratory symptoms were significantly associated with the high levels of long-term exposure estimated by the model. The highest risk was for chronic bronchitis symptoms (>4-fold higher for exposures of 0.1 mg/m3 of respirable dust). Conclusion. The presented modeling strategy can be used to estimate the long-term average personal exposure to respirable dust, and to study the association between dust exposure and chronic respiratory symptoms. This population of workers will be followed-up in subsequent examinations (3 years later) to determine whether the predictive model is valid, and whether long-term dust exposure is related to the incidence of respiratory symptoms and changes in pulmonary functions.

Opis:
In transposing Directive 2013/59/Euratom (European Basic Safety Standards or EU BSS) into national law, it was necessary to identify industrial sectors which involve naturally occurring radioactive materials (NORM) which may lead to public exposure that cannot be disregarded from a radiation protection point of view. A research project was implemented that resulted in a comprehensive survey of all potentially relevant industrial sectors operating in Germany. Major efforts were made to determine source terms of airborne discharges, atmospheric dispersion models, and dose calculations. The study arrived at the conclusion that the discharge and the settlement of dust in agricultural and horticultural areas is the most relevant dispersion and exposure pathway, while discharges of radon are of minor importance. The original study used a number of rather complex models that may distract from the fact that very few key parameters and assumptions determine the effective dose of members of the public. This paper revisits the study and identifies those parameters and assumptions and provides a simplified, generic, yet sufficiently reliable and robust assessment methodology to determine the radiological relevance of dust discharges from NORM industries under the typical geographical and meteorological conditions of Germany. This paper provides examples of dose estimates for members of the public for selected industries operating in Germany. Due to its simplicity and robustness, the methodology can also be used to assess effective doses resulting from discharges in other industries in Germany, and it can be adapted to conditions in other countries in a straightforward way.

Opis:
Objectives. The objectives of this cross-sectional study were to investigate dust exposure and respiratory health of workers in duck hatcheries in western France. Method. Ninety volunteer workers, who work in sorting rooms and/or incubation rooms, participated in exposure assessments and medical examinations. Medical examinations were performed by occupational health practitioners. They filled-in a questionnaire with the workers, followed by a lung function test on each worker. General characteristics and prevalence of chronic respiratory symptoms were described in each type of working rooms. Associations between symptoms and exposure (working room or dust level) were studied in GEE multivariate models. Results. Overall prevalence of chronic respiratory symptoms (cough, phlegm) and chronic bronchitis were similar or lower than in the reference population. However, prevalence of these symptoms was higher for those working in sorting rooms, that were associated with an increased risk of respiratory symptoms and decreased lung function. Respirable dust was also significantly associated with an increased risk of respiratory symptoms. The prevalence of asthma and rhinitis were well above those in the reference population, but did not vary among working rooms. Descriptive data suggested an occupational origin for some cases. Conclusion. Hatchery workers were at increased risk of compromised respiratory health due to dust exposure, particularly those who work in sorting rooms. Asthma and rhinitis were in excess in this population of workers. Thorough clinical examination of these workers should be performed and all exposures assessed.

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.
