Persistence of Atrazine and Occurrence of Its Primary Metabolites in Three Soils

Atrazine (2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine) degradation in various soils under laboratory conditions was studied. Atrazine was depleted mostly through microbial degradation in alkaline soil and was degraded in acidic soil mainly through chemical transformation or both chemical a...

Description
Summary:Atrazine (2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine) degradation in various soils under laboratory conditions was studied. Atrazine was depleted mostly through microbial degradation in alkaline soil and was degraded in acidic soil mainly through chemical transformation or both chemical and microbial transformation. The microbial degradations of atrazine produced desethylatrazine and desisopropylatrazine as primary metabolites, while chemical degradation of atrazine yielded hydroxyatrazine. Atrazine decreased 3−4 times faster in soils at 25 °C than at 10 °C. Keywords: Atrazine; metabolite; degradation; soil; persistence
