In order to investigate the harmful trace elements in Korean common food, the contents of copper, lead, cadmium, mercury, arsenic, manganese and zinc are studied.
As shown in the table Ⅱ, the following food samples collected from the agricultural field were used;
cereals-rice, barley, soybean, corn
vegetable-raddish, chines cabbage, tomato, cucumber, potato
Fruits-grape, peach, pear, melon, watermelon, Apple.
Contents of copper, lead, cadmium manganes and zinc were determined by means of atomic absorption spectrophotometry (Jarrell-Ash Atomic Absorption Spectrophotometer) and the mercury and arsenic were determined by spectrophotometry (Beckman model DU Spectrophotometer).
The results obtained are shown in table Ⅲ.
1. The ued samples and species in this study were similler with those of previous reprot(1972). But much more samples had collected from the are as where the comparatively less containated and country widely.
2. The results were shown that the contents of harmful trace elements (Cu, Cd. Pb, Hg, As.) of Korean food were significantly lower than the foreign standards.
3. This studies were conducted as a continuation of the first report (1972).
