||Worker exposure to airborne lead particles was evaluated for a total of 117 workers of four different industries in Korea. The particle sizes were measured using 8-stage cascade impactors worn by the workers. Mass median aerodynamic diameters and size distributions as a function of airborne lead (PbA) concentration were determined by type of industry. Blood lead (PbB) levels of workers were also examined. The results indicate PbB correlated better with respirable lead concentrations than with PbA which implies that the contribution of respirable lead particles to lead absorption is greater than that of PbA. This study concludes that the measurement of PbA only may not properly reflect a worker's exposure to lead particles with diverse characteristics. For the evaluation of a worker's exposure to various types of lead particles, it is recommended that respirable lead particles as well as PbA be measured.
