The OEHSA uses a conceptual site model to describe potential exposure pathways
which serve as the basis for developing the site surveillance and analysis plan.
Six publications evaluated the impact of specific tasks on the paraoccupational exposure pathway
In vitro bioaccessibility assessments (IVBA) were performed on a subset of processed ores, soils, and sweep samples to model toxicant bioaccessibility and bioavailability along ingestion exposure pathways
(Drexler and Brattin 2007; Morman et al.
MDH also looked at whether any completed exposure pathways
existed and whether any completed exposure pathways
might exist in the future.
This multimedia transport pathway evaluation must occur before addressing the other questions raised by the exposure pathway
Variable Baseline value Inhalation Dermal DEHP concentration in 2.
We used this analysis to assess the prospects for emissions reductions and to identify gaps in present understanding of the Hg exposure pathway
Is house dust the missing exposure pathway
Examples of neurobehaviorally active substances with multiple exposure pathways
The risk estimates by exposure pathway
remained elevated and in some cases increased after restricting the cases to those who responded to a follow-up survey and confirmed that they had a physician-diagnosed SAID or RA specifically.
For each exposure pathway
, we divided person-years of potential exposure into three categories: zero and below and above the 75th percentile of nonzero values.
Our recent articles provide new information regarding the dietary exposure pathway
for several OP pesticides.
An empirical comparison of lead exposure pathway
The importance of this additional exposure pathway
can be fully assessed when accurate estimates become available for a) soil physicochemical properties and contamination pattern beneath CCA-treated structures, b) children's daily soil intake values, and c) relative oral bioavailability of arsenic in CCA-contaminated soils.
Furthermore, Lioy's research resulted in more precise risk and policy calculations revealing heretofore unrecognized exposure pathways
such as dermal absorption during bathing and showering to disinfectant by-products found in tap water, and the uptake of sprayed indoor pesticides into children's toys, with resultant significant exposure.
