Soil residues in a tobacco field yearly treated with a soil insecticide, Heptachlor, was analyzed by GLC equipped with electron capture detector(ECD). In addition, translocation of the heptachlor residues into two staple vegetables, radish and chinese cabbage was also studied under field conditions. The results were summarized as follows; 1. The Heptachlor residues in the soil of tobacco plots were less than 0.010 ppm. 2. The Heptachlor residues in radish and chinese cabbages cultivated in the tobacco plot were also below 0.010 ppm. 3. Amount of Heptachlor residues translocated into the vegetables were not related to the concentrations of the residues in the soil.
