Water-solubility studies were made with aldrin, dieldrin, heptachlor, and heptachlor epoxide. The solubility curves indicate an initial drop followed by a significant increase in solubility occurring during the first 3 or 4 days before a plateau is r

Data are presented to delineate (1) the rate and extent of aldrin conversion to dieldrin and (2) the rate of residue (aldrin + dieldrin) dissipation in Illinois soils. Formulae were developed to estimate with reasonable accuracy accumulated residues
