Abstract A study on the management and improvement of the work environment was conducted from 1990 to 2000 at 259 lead-handling factories in Japan. Data were obtained by means of questionnaires addressed to employers. Various factors affecting blood lead levels (PbBs), including gender, age, employment duration, factory size, work environment control and job categories were analyzed. The PbB of men was found to be higher than that of women, and may be due to the differences in job distribution. PbB increased along with increasing age and employment duration. PbB declined as the factory size increased. The odds ratio (OR) of PbB higher than 20µg/dL according to factory size was significantly high even after adjusting for work environment control class. This demonstrates that not only the working environment but also safety management was poorer among small-scale factories than among large-scale factories. Smelting or refining lead had the highest risk for lead exposure while painting had the lowest risk. Other findings are discussed.
