Opis:
The aim of the study was to evaluate the combined effect of noise exposure and additional risk factors on permanent hearing threshold shift. Three additional risk factors were: exposure to organic solvents, smoking and elevated blood pressure. The data on exposure and health status of employees were collected in 24 factories. The study group comprised of 3741 noise male exposed workers of: mean age 39§8 years, mean tenure 16§7 years and LEX;8h = 86 § 5 dB. For each subject, hearing level was measured with pure tone audiometry, blood pressure and noise exposure were assessed from the records of local occupational health care and obligatory noise measurements performed by employers. Smoking and solvent exposure were assessed with questionnaire. The study group was divided into subgroups with respect to the considered risk factors. In the analysis, the distribution of hearing level of each subgroup was compared to the predicted one which the standard calculation method described in ISO 1999:1990. For each of the considered risk factors, the difference between measured and calculated hearing level distribution was used to establish, by the least square method, a noise dose related correction square function for the standard method. The considered risk factors: solvent exposure, smoking and elevated blood pressure combined with noise exposure, may increase degree of hearing loss.

Opis:
Background: Physical activity (PA) has a positive effect on human health at all ages and it is especially important in older people. When insufficient, it may lead to the deterioration of a person’s health status. Aim of the study: The aim of the study was to assess the declared PA of the Universities of the Third Age (U3A) students and to examine the relationship between the level of PA, physical performance, and quality of life in this population. Material and methods: The study included 99 subjects, aged ≥60 years, with a Mini Mental State Examination score ≥24. Participants were examined using the International Physical Activity Questionnaire (IPAQ), the Short Form Health Survey (SF-36) questionnaire, the Short Physical Performance Battery (SPPB), the Activities of Daily Living scale (ADL), the Lawton Instrumental Activities of Daily Living scale (IADL), and the short form of the geriatric depression scale (GDS). Handgrip strength (HS) was measured using the baseline hydraulic dynamometer. Results: Statistically significant differences in the results of women and men were demonstrated in 5 variables: the level of PA measured with the IPAQ, physical component summary of the SF-36 questionnaire, the total SPPB score, HS of the dominant hand and the non-dominant hand. In all examinations, men obtained higher scores than women. Positive correlations between PA and the result of the ADL, IADL, SPPB, HS and physical component summary of the SF-36 questionnaire were shown. Conclusions: The study confirmed that the participants of the U3A classes mostly meet the recommendations regarding minimum PA and they willingly undertake regular PA. It translates into high functional and physical fitness, stronger muscles and a good QoL.

Opis:
In this work, scanning electron microscopy with energy dispersive X-ray spectrometry (SEM-EDS) and the time-of-flight secondary ion mass spectrometry (TOF-SIMS) were used to study the particles present on the hair surface of the inhabitants of Wislinka (people environmentally exposed due to the closeness of a dump) in order to obtain the information about the possible influence of dusting from a phosphate waste deposal place. Additionally, the morphology and the composition of fresh phosphogypsum were analyzed. Waste phosphogypsum is formed in the process of a wet phosphoric acid production and there is still a problem with its storage. A thorough understanding of the composition and chemistry of phosphogypsum seems to be necessary to evaluate its environmental impact comprehensively. The results obtained from these two techniques turned out to be complementary and revealed the information expected.

Opis:
Determination of trace elements in combusted materials has always been an interesting field of environmental studies. Particulate matter, in particular, is a serious problem which, can lead to air pollution especially by heavy metals emissions in urban and industrial areas. There is a considerable concern about the elevated level of mercury released during combustion and the proportion of anthropogenic mercury in the environment. Nowadays, small-scale installations have been identified as a significant source-pathway for mercury pollution, particularly those that use coal. A total amount of mercury was determined using Mercury Analyzer. The investigated material consists of bottom ash, fly ash, slag, soot or dust. The obtained results varied according to the type of the material and plant. The developed methodology was checked by carrying out the analysis of certificate material of Soil NCS ZC 73001 and the reference material of Soil-7.

Opis:
The aim of the study was to assess the hearing threshold levels (HTLs) in employees exposed to noise generated by low-frequency ultrasonic technological equipment in comparison with the HTLs of workers exposed to audible noise at the similar A-weighted equivalent-continuous sound pressure level. The study includes measurements of ultrasonic and audible noise at workplaces and hearing tests, i.e. conventional pure-tone audiometry and extended high-frequency audiometry. The study group comprised 90 workers, aged 41.4 ± 10.0 years (mean±SD), exposed for 17.3 ± 9.8 years to noise generated by ultrasonic devices at mean daily noise exposure level (‹LEX,8h›) of 80.6 ± 2.9 dB. The reference group consists of 156 subjects, exposed to industrial noise (without ultrasonic components) at similar A-weighted equivalent-continuous sound pressure level (‹LEX,8h› = 81.8 ± 2.7 dB), adjusted according to age (39.8 ± 7.7 years), gender and job seniority (14.0 ± 7.0 years). This group was selected from database collected in the Nofer Institute of Occupational Medicine. Audiometric hearing threshold levels in the frequency range of 0.5–6 kHz were similar in both groups, but in the frequency range of 8–12.5 kHz they were higher in the group of employees exposed to ultrasonic noise. The findings suggest that differences in the hearing threshold (at high frequencies) in analyzed groups may be due to differences in spectral composition of noise and show the need to continue the undertaken studies.
