Journal of occupational and environmental hygiene, 12(5), 287-93.More infoNoise exposures and hearing loss in the mining industry continue to be a major problem, despite advances in noise control technologies. This study evaluated the effectiveness of engineering, administrative, and personal noise controls using both traditional and in-ear dosimetry by job task, work shift, and five types of earplug. The noise exposures of 22 miners performing deep shaft-sinking tasks were evaluated during 56 rotating shifts in an underground mine. Miners were earplug-insertion trained, earplug fit-tested, and monitored utilizing traditional and in-ear dosimetry. The mean TWA8 noise exposure via traditional dosimetry was 90.1 ± 8.2 dBA, while the mean in-ear TWA8 was 79.6 ± 13.8 dBA. The latter was significantly lower (p < 0.05) than the Mine Safety and Health Administration (MSHA) personal exposure limit (PEL) of 90 dBA. Dosimetry mean TWA8 noise exposures for bench blowing (103.5 ± 0.9 dBA), jumbo drill operation (103.0 ± 0.8 dBA), and mucking tasks (99.6 ± 4.7 dBA) were significantly higher (p < 0.05) than other tasks. For bench blowing, cable pulling, grinding, and jumbo drill operation tasks, the mean in-ear TWA8 was greater than 85 dBA. Those working swing shift had a significantly higher (p < 0.001) mean TWA8 noise exposure (95.4 ± 7.3 dBA) than those working day shift. For percent difference between traditional vs. in-ear dosimetry, there was no significant difference among types of earplug used. Reflective of occupational hearing loss rate trends across the mining industry, this study found that, despite existing engineering and administrative controls, noise exposure levels exceeded regulatory limits, while the addition of personal hearing protection limited excessive exposures.

Fire Technology, 50(5), 1043-1059.More infoFirefighting remains a dangerous profession. The objective of this study was to compare injury rates among career and volunteer fire departments internationally. Methods: Injury and staffing data were collected for 2004-2009. All reported, lost-time, and activity-specific injury rates were calculated for fireground, medical, training and physical exercise activities. Injury rates were also adjusted for number of fireground and medical responses, and average annual training hours. Injury rates were generally higher in the U.S. than in Commonwealth nation and Japanese fire departments. Lost-time injury rates varied markedly among fire departments, from 0.6 (95% CI 0.4-0.9) to 23.5 (95% CI 22.4-22.7) injuries per 100 firefighters per year. The greatest pair-wise differences in lost-time injury rates were seen in the fireground and medical call activities, and these differences persisted when the rates were adjusted by the number of firefighters responding to fireground and medical incidents, respectively. Injury rates vary substantially across fire departments, suggesting that substantial improvements could result from adoption of more optimal health and safety approaches.

Journal of exposure science & environmental epidemiology, 24(2), 150-155.More infoExposure to arsenic in drinking water is associated with increased respiratory disease. Alpha-1 antitrypsin (AAT) protects the lung against tissue destruction. The objective of this study was to determine whether arsenic exposure is associated with changes in airway AAT concentration and whether this relationship is modified by selenium. A total of 55 subjects were evaluated in Ajo and Tucson, Arizona. Tap water and first morning void urine were analyzed for arsenic species, induced sputum for AAT and toenails for selenium and arsenic. Household tap-water arsenic, toenail arsenic and urinary inorganic arsenic and metabolites were significantly higher in Ajo (20.6±3.5 μg/l, 0.54±0.77 μg/g and 27.7±21.2 μg/l, respectively) than in Tucson (3.9±2.5 μg/l, 0.16±0.20 μg/g and 13.0±13.8 μg/l, respectively). In multivariable models, urinary monomethylarsonic acid (MMA) was negatively, and toenail selenium positively associated with sputum AAT (P=0.004 and P=0.002, respectively). In analyses stratified by town, these relationships remained significant only in Ajo, with the higher arsenic exposure. Reduction in AAT may be a means by which arsenic induces respiratory disease, and selenium may protect against this adverse effect.Journal of Exposure Science and Environmental Epidemiology advance online publication, 10 July 2013; doi:10.1038/jes.2013.35.
