Abstract
Residue data for samples taken in January 1969 from plots treated with water emulsions of the insecticides by plant or soil application regularly for fifteen years (1953-1968) have been previously reported. In the present work, samples of the plots were taken in September 1973 following fallowing and cropping. No significant decrease in dieldrin, o,p'DDT and p,p'-DDT residues had occurred. Lindane residues had significantly decreased while p,p'-DDE had doubled. Transport into lower layers was very limited. Concentrations in roots were 5-15 times higher than those in soil, but shoots of the final crop (Lolium perenne) contained little residues.
