The relationship between the fate of clomeprop in soil and its phytotoxic activity on the growth of radish (Raphanus sativus) seedlings was investigated in the laboratory. The phytotoxic activity of clomeprop in sea sand was much higher than in non-autoclaved soil, and the phytotoxic activity in non

## Abstract The removal of hydrocarbons from contaminated soil is an essential practice because of environmental concerns, and in order to avoid surface and groundwater contamination. There are different methods applied to remove the hydrocarbons from the soil environment. However, the efficiency o
Triazole fungicides are now widely used commercially and several are known to be persistent in soil. The degradation rates of ยฎve such fungicides were measured in laboratory tests with two soils over 720 days, with analysis of soil extracts by high-pressure liquid chromatography. Behaviour in a sand
The criteria for registering pesticides persistent in soil are still a matter of debate. Amongst modern pesticides, several triazole fungicides are very persistent, though no deleterious effects on soil microbial processes have been reported. The behaviour of ยฎve such compounds (ยฏutriafol, epoxicona
