Abstract

We conducted this study, to obtain basic data of lead concentrations in children of Ulsan industrial area and to evaluate the difference in blood lead levels between industrial area and suburban area. The study subjects were composed of 348 school children residing in industrial area and 100 school children of suburban area. There is no difference in age and sex distribution of study participants between industrial and suburban area. The obtained results were as follows: l. The geometric means of blood lead levels of study participants were 4.90 ng/dl, which is lower than current acceptable value 10 ng/dl. 2. The children residing in industrial area had the higher blood lead levels(5.26 ng/dl) than suburban children(3.81 ng/dl) with statistical significance(P<0.001).
