Epidemiological significance of determination of lead cadmium copper and zinc in hair and permanent teeth in persons living in the vicinity of a lead smelter

Content of Pb, Cd, Cu and Zn was analyzed by atomic absorption spectrophotometry (model Unicam SP 90) in hair of 200 persons residing in immediate vicinity (within a distance of 5 km) of a Pb smelter and in a control group of 200 persons living at a distance greater than 10 km from main air pollution source. Statistically significant differences in content of metals were found (probability range 0.05-0.01). Concentration of Pb, Cd, Cu and Zn in permanent teeth was also analyzed in relation to distance of residence from Pb smeltery in 111 persons living 1-5 km from it and in 23 persons living in the area 20-30 km away. Established differences were statistically significant for all analyzed metals with exception of Zn.
