• W83752761 abstract "An experimental plot has been established on a calcareous soil in southern England to investigatethe fate and transport of diuron (N`-[3,4-dichlorophenyl]-N,N-dimethylurea), a commonly usedphenylurea herbicide. In early January 2001 an agricultural grade of diuron was applied to thesoil surface at a rate of 6.7 kg/ha along with a potassium bromide conservative tracer applied at200 kg/ha. Hand augured samples were taken at regular intervals over the next 50 days, and thenagain after 338 days, with samples collected down to 54 cm. Porewaters were extracted from thesoil cores by using high speed centrifugation and the supernatant fluids were retained foranalysis by HPLC for diuron and three of its metabolites, N`-[3,4-dichlorophenyl]-N,Nmethylurea(DCPMU), N`-3,4-dichlorophenylurea (DCPU) and 3,4-dichloroaniline (DCA). Thecentrifuged soil was retained and then extracted with methanol prior to HPLC analysis for thesame suite of phenylureas. A mass balance approach showed large variations in diurondistribution but on average accounted for 104% of the diuron applied. Concentrations of diuronand its metabolites were roughly five times higher in the soil than in the soil porewaters. After 50days metabolites comprised 10% of the total diuron present in the porewater and 20% of the totaldiuron sorbed to the soil matrix. After 36 days a large pulse of diuron and DCPMU appeared inthe porewaters and soil matrix at a depth of 54 cm, travelling an average of 0.15 cm/d faster thanBr. A preferential route for diuron transport is suggested. There is evidence to suggest thatdegradation occurs at depth as well as at the soil surface. Metabolites generally appear to movemore slowly than the parent compound. All metabolites were encountered but interpretingtransport and degradation processes simultaneously proved beyond the capability of the study.Diuron was detected once in a shallow (5 m) observation well situated on the experimental plot.High concentrations of diuron and metabolites were still present in the soil and soil solutionsafter 50 days. After 338 days diuron was absent from the porewaters but still resided in the solidphase. The metabolite DCPU became the dominant compound in the soil solution whereasDCPMU was dominant in the sorbed phase. Both compounds remained as a source of potentialgroundwater contamination." @default.
