Respiratory tract depositions
|Abstract:||This paper estimates personal exposure to particulate matter (PM), deposition and status of selected toxic metals in respiratory tract washout samples obtained from 20 humans residing in township of an industrial environment in central India. All humans samples for personal PM exposure and respiratory tract depositions, collected during winter season, were analyzed for selected toxic elements (Pb, Cr, Cd, Co and Ni). Personal PM₅ exposure levels were found between 2.6-48.6 µg/m³ for various categories. Chemical analysis of PM samples shows that higher risk is associated with housewives who spend their time (> 85%) indoors. Good positive correlation coefficient value is found for PM concentrations and respiratory tract depositions.|
