Objective:
This study investigated the relationship between personal breathing zone air samples and associated biological monitoring urine samples collected in the US Department of Energy Operations.
Methods:
We performed standard descriptive analyses of the air sample and Biological Exposure Index monitoring data. We also provide a list of direct-reading instruments used in mercury field assessments.
Results:
A total of 2330 air samples and 265 Biological Exposure Index data were analyzed. These data were grouped into 16 job titles, excluding categories with fewer than 10 samples, which resulted in 11 job titles.
Conclusions:
We conclude that industrial hygiene airborne sample data alone may not provide a complete assessment in exposure determination. We suggested the necessity of incorporating biological monitoring to determine the exposure.
