To quantify risk of ambient exposure to airborne particulates around industrial silica sand operations, this study used EPA-certified federal reference method monitors to measure the levels of PM10 and PM2.5 particulate matter. The monitoring sites were chosen based upon EPA siting criteria, dichotomous samplers were calibrated before and after sampling, and pre- and post-weight filter weights were recorded. PM2.5 levels were significantly higher (paired t-tests) at both sites - averages of 7.70 ± 6.15 and 22...

OBJECTIVES: The incidence of ODs is below expectations. The approaches of family physicians is very important. In this study, we aimed to evaluate attitudes and behaviors of family physicians about ODs. METHODS: The questionnaire was first sent to family physicians via e-mail. Of 3663 responders, 3090 replies were included to study. RESULTS: 44.1% of them stated they obtained detailed occupational history. In logistic regression analysis, physicians who obtained detailed occupational history, discussed with occupational physician about their patients' health, had education about ODs and those who stated that they wanted to receive training in ODs were more likely to refer their patient...

We examined the association between acute exposure to sulfur dioxide (SO2) and mortality, using historical data from 1972-1991 in Yokkaichi, Japan. We used a time-stratified case-crossover study design. We included all causes of death, excluding external causes, between 1972 and 1991 in Yokkaichi and the neighboring town, Kusu of the Mie Prefecture (N = 29,839). We obtained daily estimations of SO2 concentrations during the study period. We then conducted conditional logistic regression analysis to examine association between SO2 exposure and all-cause and cause-specific mortality...

Oxidative stress and DNA damage are considered as possible mechanism involved in lead toxicity. To test this hypothesis, DNA damage and expression variations of ALAD, SOD2 and OGG1-2░a genes was studied in a cohort of 100 exposed workers and 100 controls with comet assay and real-time PCR. Results indicated that increased number of comets was observed in exposed workers versus controls (p<0.001). After qPCR analysis, significant down-regulation in ALAD (p<0.0001), SOD2 (p<0.0001) and OGG1-2░a (p<0...

Few studies have evaluated airborne exposures to benzene, toluene, ethylbenzene, and xylenes (BTEX) during operation of two-stroke and four-stroke small engines, such as those in lawn maintenance equipment. Full-shift, 8-hour personal samples were collected during a simulation study to characterize yard maintenance activities including mowing, trimming, and fueling. Short-term, 15-minute personal samples were collected to separately evaluate mowing and trimming exposures. Mean 8-hour time weighted average (TWA) BTEX concentrations were 2...

BACKGROUND: Though there is extensive research on occupational exposure in production mines, there is limited information on exposure during the exploration phase of mining. METHODS: Air samples were collected in a core processing facility in Northern Ontario, Canada. All samples were analyzed for respirable dust (NIOSH 0600) and respirable crystalline silica (NIOSH 7602). Mean exposure levels were estimated and differences in exposure between work areas were investigated...

As mental health goes beyond the simple absence of mental disorders, this paper characterized mental health components in 89 underground coal miners in southern Brazil. This is a cross-sectional study, that detected a low prevalence of depression; light or moderate anxiety in 13% of the workers; self-perception of good health; life quality and good psychological capacity in most of the participants; poor sleep quality in half of them; reverse correlations between anxiety and life quality, and anxiety and psychological capital; positive correlations between psychological capital and life quality; associations between self-perception of health, time, and sleep quality; associations between anxiety and sleep duration and quality; and between alcohol consumption and location at work (front, rear, or variable)...

Previous studies report high respirable silica exposures among clay brick workers globally; however, there are little data on exposures among workers in fixed chimney Bull's trench kilns, the predominant kiln type in Kathmandu valley, Nepal. We investigated respirable silica exposures among workers (N = 46) in five similar exposure groups (SEGs). Mean exposures were highest for red brick loading/carrying (331 μg/m3), followed by green brick stacking (223 μg/m3), fireman (102 μg/m3), coal crushing/carrying (92 μg/m3), and green brick molding (71 μg/m3)...

Metal contamination was studied in locally rearing chicken and eggs in the environs of mining areas of Singhbhum copper belt. Concentrations of metals were below Indian standards except for Cu, Ni and Zn in the case of chicken at some locations. Estimated daily intake (EDI) and target hazard quotient (THQ) suggested that the metals did not pose risk individually. However, considering the geometric mean of the metals, hazard index (HI) was above unity. Cu, Pb and Co were the key components contributing to a potential noncarcinogenic risk...

The purpose of this study was to measure the concentration of carbon black and BTEXs at three photocopy centers and to assess the health risk following exposure. Air samples were collected by sampling in the breathing zone of workers during the class and examination periods. The results found that the concentration of carbon black before operation was higher than morning and afternoon in both class and examination periods. These levels are considerably lower than the suggested limited value set by OSHA. Toluene had the highest concentration but did not exceed of recommended exposure limit by NIOSH...

The Part 90 program was designed to prevent progression of pneumoconiosis in U.S. coal miners by establishing their right to transfer to a less dusty job in the mine. We calculated the proportion of Part 90-eligible miners who participated during 1986-2016, examined participation by region, and compared characteristics of miners by participation status. Of the 3,547 eligible miners, 14.4% exercised their Part 90 option. Miners working in states outside central Appalachia, and those with more severe pneumoconiosis, were more likely to participate...

Recent studies suggest that heat exposure degrades work productivity, but such studies have not considered individual- and workplace-level factors. Forty-six tree-fruit harvesters (98% Latino/a) from 6 orchards participated in a cross-sectional study in central/eastern Washington in 2015. The association between maximum measured work-shift wet-bulb globe temperature (WBGTmax) and productivity (total weight of fruit bins collected per time worked) was estimated using linear mixed-effects models, adjusting for relevant confounders...

Today, we can see a trend toward increased psychosocial strain at work among home-care managers and staff. The aim of this study is to describe home care managers' views on their own psychosocial working conditions and on how to promote workplace health and safety in a municipality in northern Sweden. A mixed-methods design was used, including questionnaire and qualitative focus group data. The qualitative data were analyzed by manifest content analysis. The results indicate that most managers perceived increased variety in work and opportunities for development at work, but at the same time increased demands...
