Tea leaves grown in a field that had been treated in the nearby top soil with 75% DDT 1 kg per hectare, 50% Dieldrin 10 kg per hectare, or 2.5% Heptachlor 50 kg per hectare were analyzed separately. Dieldrin residues accumulated to a maximum of over 0.20ppm. DDT and both Heptachlor and its metabolite, Heptachlor Epoxide, were much lower than that of Dieldrin, with only a few samples detectable.
