Workers' health on the new "long march": occupational health in the People's Republic of China.

China's drive to modernize its economy will produce new occupational health problems even as it resolves earlier ones. Well aware of this, Chinese occupational health experts are intensifying efforts to improve workers' health and establish a modern occupational health program. Occupational lung disease, occupational cancer, heavy metal poisoning, industrial chemical poisoning, and physical factor-induced diseases (noise and heat) have all been targeted for expanded research which will serve as a basis for standard setting. Hazard control efforts include engineering controls, particularly in new construction, limited use of personal protective equipment, and expansion of environmental and medical monitoring. Worker education and professional activities have been expanded. International exchanges have been initiated and will prove occupational health a promising area of scientific cooperation.
