Both dermal patch loadings of chlorpyrifos and measurements of a chlorpyrifos-specific metabolite (TCPy) in urine confirmed substantial exposure to and skin absorption of chlorpyrifos that varied according to job category; and dermal patch loading was significantly higher on the thighs than on the forearms.
In this report, researchers describe evidence of substantial exposure to BPA and other potential endocrine disruptors through medical treatment of premature infants [ EHP 117:639–644; Calafat et al.].
Our study was restricted to drugs with substantial exposure in THIN, and the scope of the structured assessment was adapted to the available data.
We recommend that testing for CAL (and specifically for JCV) infection should be strongly considered in the setting of severe sepsis in adults with substantial exposure to mosquitoes and no other identifiable source of sepsis.
Univariate analyses of domestic and neighbourhood exposures and work with other asbestos products (heat-protection materials, gaskets and brake linings) were restricted to cases who had only done low-risk industrial or non-industrial work not involving substantial exposure (groups 7 and 8).
We show results corresponding to ever exposure and to substantial exposure, as defined above.
Pesch et al. (2000) observed odds ratios (ORs) of 1.0, 1.2, and 1.8 for the medium, high, and substantial exposure categories, respectively; however, the pattern was more variable in the nested case control study by Lynge et al. (2006), in which duration of dry-cleaning work was used as the exposure measure.
Geographically diverse from coast to coast across 30 states - and substantial exposure to the East Coast - Monmouth focuses on major seaports, intermodal ports, and airports.
Dr. Cecile Rose, director of the occupational and environmental medicine clinic at National Jewish Health, said that while investigation of these exposures are in their infancy, she is seeing a number of returning troops who suffer from respiratory diseases -- virtually all of whom say they experienced substantial exposure to dust storms and burn pits while overseas.
