Popis:	Bioassay and residue analysis data on termiticide-treated soils revealed that after 7 years of exposure in the field there were wide differences among the soils treated with the termiticides both in toxicity, or the availability of the toxicants to the test termites, and residues, and the toxicities and residues were not closely related. On the basis of the 7th-year toxicity to test termites, soils treated with 7 termiticides ranked in the following order: dieldrin> aldrin> heptachlor> chlordane > DDT> lindane > sodium arsenite. In relation to residues present the order was DDT > chlordane > heptachlor and heptachlor epoxide > aldrin and converted dieldrin> dieldrin > lindane > sodium arsenite. A further ranking on the basis of percentage of termiticide remaining was DDT> dieldrin > chlordane > aldrin and converted dieldrin > heptachlor and heptachlor epoxide > lindane > sodium arsenite. Additional bioassay data were obtained at the end of the 8th and 9th years, and from the standpoint of toxicity, after 9 years dieldrin and aldrin were clearly superior to the other termiticides in the tests.
