We analyzed blood lead (PbB) level from the 2003 health surveillance results of 13,043 lead workers from 1,217 total lead industries to evaluate lead intoxication at low level in Korea. Geometric mean of PbB was 6.08 μg/dl and 56.6% and 7.9% of total lead workers had PbB level over than 5 μg/dl and 25 μg/dl, respectively. Male showed relatively higher PbB level compared to women, but "Manufacture of Other Electronic Valves, Tubes and Electronic Components n.e.c." had more women than male in risk of low level lead exposure. While conventional high-risk industry such as "Manufacture of Accumulators" and "Other Basic Non-ferrous Metal Industries" were remained in high-risk group in lead exposure, there were high risks in other industries such as plastic, chemical and part manufacturing. Non-production tasks such as fork lift truck driving, maintenance, lab testing, and supporting function showed high blood lead level in addition to routine manufacturing processes such as smelting and soldering.
