Enrichment of the agricultural herbicide atrazine in the microsurface water of an estuary

The authors have used a microsurface water sampling technique, with a 16 mesh stainless steel screen collecting bulk samples from the top 100-150 um of the surface, to study the enrichment of atrazine in a river in Maryland, U.S.A. The sampling periods were June-December 1977 and 1978 and the maximu...

Description
Summary:The authors have used a microsurface water sampling technique, with a 16 mesh stainless steel screen collecting bulk samples from the top 100-150 um of the surface, to study the enrichment of atrazine in a river in Maryland, U.S.A. The sampling periods were June-December 1977 and 1978 and the maximum concentration, 3.3 ug per litre, was detected in August, 1977. Concentrations decreased at the end of October, in both microsurface and bulk surface water. The enrichment of atrazine in the microsurface varied from none to 110 times, with the highest enrichment between mid-September and late October. Atrazine concentration in the actual microsurface is estimated to vary in the range 150-8850 ug per litre.
