Abstract

Soils from DDT-sprayed forest stands in New Brunswick and Maine contained DDT residues. The residues increased in successive samplings between 1958 and 1961, although no new spray was applied. The increase suggests that DDT residues may persist for several years in tree canopies but are ultimately carried into the soil
