Along with changing technology, new regulations, socio-economic impacts, occupational lead exposure in Taiwan in recent years has been modifined. By examining lead-related industries, including battery recycling, lead powder, lead stabilizing agents, cable, printing, glaze, leaded glass, drifting net, petroleum, ship demolition, electronic soldering, it was found that most occupational exposure has been significantly reduced. Factors such as automation, granulation, new technology with little or no lead, stringent environment and occupational health regulations, the shutdown of obsolete and polluted factories, societal changes (including labor shortages & changes in human value concepts), and international trade factors unfavorable to leadrelated businesses, are the driving forces in the lowering of occupational lead exposure.
