Abstract

To know a degree of pollution in agricultural products cultivated around 4 unworked mines located in Chollanam-Do, we investigated a concentration of heavy metal and trace metal to provide the basic data for its residual limits. 28 samples of seven kinds of agricultural products(lettuce, onion, potato, radish, pepper, pumpkin, bean) collected from 4 unworked mines located in Chollanam-Do in 2001 were analyzed by Mercury Analyzer for mercury and Atomic Absorption spectrophotometer for Pb, As, Cd, Cu, Mn, and Zn. Hg contents were detected N.D. ∼trace level(0.01 ppm and less) and As content were detected N.D. ∼ 0.029 lpm but most of same)leE were not detected. Cd contents were detected N.D∼0.124 ppm. The results of Hg, As, Pb and Cd content showed that for all the 7 species of agricultural products studied, none have accumulated levels dangerous enough to Pose health problems. The average contents of Cu were 3.070 ∼ 7.825 ppm in bean, the Mn were 3.688 ∼23.935 ppm in lettuce ailed the Zn were 5.690 ∼21.171 ppm in bean, respectively.
