Industrial hygienists use personal samplers to estimate mean breathing zone concentrations of contaminants. The sampling inlet typically is suspended from the worker's lapel. Lapel concentrations are not proven representatives of inhaled concentrations. Researchers have found differences between concentrations at the lapel and at other sites closer to the nose and mouth.
Asthma development in aluminum smelter workers has been attributed to fluoride exposures in the potroom environment. This work focused on the relationship between air and urinary fluoride concentrations to determine if urinary fluoride concentrations could be used as a reliable measure of an individuals dose.
This study validated a linear regression model describing lead exposure in the demolition industry. A previous lead study (Phase 1) of the demolition industry described lead exposure for many common demolition tasks by use of a multiple regression model. In this study 38 samples were obtained to validate the Phase 1 regression model.
