For the purpose of investigating the effect of occupational health service in terms of environmental control and health provision of workers on the improvement of worker´s health, authors analysed the data of environmental measurement and health check-up of one lead using industry who started his investment to environmental improvement from 1980.
Six hundred million won was invested for environmental improvement from 1980 to 1986. This investment brought about apparent improvement of working conditions of all of the workplaces from mean concentration of lead in air over 0.15㎎/㎥.
Environmental control reduced mean blood lead level from 51.2±11.5ug/㎗ in 1983 to 39.2±16.0ug/㎗ in 1986, and delta-aminolevulinic acid concentration 3.15±2.1㎎/ℓ in 1982 to 1.96±1.7㎎/ℓ in 1986, respectively. Blood ZPP levels were decreased from 76.1±58.9ug/㎗ in 1983 to 42.23±30.3ug/㎗ in 1986.
If 150ug/㎗ of blood ZPP is considered as unacceptable limit of lead intoxication, more than 10 percent of workers belonged to this category in 1983, but only 0.5 of workers showed their blood ZPP level over the 15ug/㎗ in 1986.
It was observed that no workers whose work duration were less than one year showed their blood ZPP level over 100ug/㎗, but there were high percentages of lead workers with high blood ZPP(over 150ug/㎗)who were working in uncontrolled had working condition and whose work duration were less than one year.
