Abstract

The behaviour of DDT and its analogues in ensiled grass was studied in the laboratory in containers of 1 dm³ volume. After a storage period of 60 days at 20 and 35°C, no significant decrease in the contents of p, p′-DDT, p, p′-TDE, p, p′-DDE and o, p′-DDT was found. The results suggest that ensilage with desirable fermentations is not practical to reduce DDT residues in pasture grass. Grass and alfalfa contaminated with low contents of DDT and its analogues, resulting from uptake from soil and traces of spray drift, were field-dried to hay. This drying did not result in significant changes in the contents of p, p′-DDT, p, p′-DDE, p, p′-TDE and o, p′-DDT.
