Mechanisms of mercury disposition in the body Tập 50 Số 10 - Trang 757-764 - 2007
Thomas W. Clarkson, Jayesh Vyas, Nazzareno Ballatori
AbstractToday the most widespread human exposures to mercury are to mercury
vapor emitted from amalgam tooth fillings, to ethylmercury as a preservative in
vaccines, and to methylmercury in edible tissues of fish. This review will focus
on the mechanisms of transport of these three species of mercury. All three
species are freely moveable throughout the body. Inhaled vapor in view of its
physical ... hiện toàn bộ
Methodological issues regarding confounding and exposure misclassification in epidemiological studies of occupational exposures Tập 50 Số 3 - Trang 199-207 - 2007
Aaron Blair, Patricia A. Stewart, Jay H. Lubin, Francesco Forastiere
AbstractBackgroundConfounding and exposure misclassification are issues that
concern epidemiologists because of their potential to bias results of studies
and complicate interpretations. In occupational epidemiology both are routinely
raised to argue that an observed result is either a false positive or a false
negative finding. Although it is important to consider the potential for
limitations of... hiện toàn bộ
Obesity and other risk factors: The National Survey of U.S. Long‐Haul Truck Driver Health and Injury Tập 57 Số 6 - Trang 615-626 - 2014
William K. Sieber, Cynthia F. Robinson, Jan Birdsey, Guang X. Chen, Edward M. Hitchcock, Jennifer E. Lincoln, Akinori Nakata, Marie Haring Sweeney
BackgroundDrivers of heavy and tractor‐trailer trucks accounted for 56% of all
production and nonsupervisory employees in the truck transportation industry in
2011. There are limited data for illness and injury in long‐haul truck drivers,
which prompted a targeted national survey.MethodsInterviewers collected data
during 2010 from 1,670 long‐haul truck drivers at 32 truck stops across the 48

But they are not thresholds: A critical analysis of the documentation of threshold limit values Tập 17 Số 6 - Trang 727-753 - 1990
S. A. Roach, Stephen M. Rappaport
AbstractThreshold Limit Values (TLVs) represent conditions under which the TLV
Committee of the American Conference of Governmental Industrial Hygienists
(ACGIH) believes that nearly all workers may be repeatedly exposed without
adverse effect. A detailed research was made of the references in the 1976
Documentation to data on “industrial experience” and “experimental human
studies.” The reference... hiện toàn bộ
Cumulative arsenic exposure and lung cancer in smelter workers: A dose‐response study Tập 15 Số 1 - Trang 31-41 - 1989
Lars Järup, Göran Pershagen, Stig Wall
AbstractThe cause‐specific mortality was followed through 1981 in a cohort of
3,916 male Swedish smelter workers employed for at least 3 months from 1928
through 1967. Arsenic levels in the air of all workplaces within the smelter
were estimated for three different time periods. Using this exposure matrix and
detailed information of the work history, cumulative arsenic exposure could be
computed f... hiện toàn bộ
Agricultural injuries among a population‐based sample of farm operators in Alabama Tập 25 Số 3 - Trang 385-402 - 1994
Chun Zhou, Jeffrey M. Roseman
AbstractA population‐based study of the occurrence of agricultural injuries
during the previous year was conducted in a simple random sample of 1,000 farm
operators in Alabama in 1991. The participation rate was 86.2%. The cumulative
1‐year incidence was 9.9% (95% CI = 7.7–12.1), based on the number of injuries,
and 7.8% (95% CI = 5.8–9.8), based on the number of farmers injured. Limbs were
