Partitioning and short-term persistence of fenitrothion in New Brunswick (Canada) headwater streams [Pesticides, water pollution, aquatic life]

Two streams were sprayed with fenitrothion, one with an aqueous formulation and the second with an oil-base formulation, and water, sediment, plant and invertebrate samples were taken downstream to examine the partitioning and persistence of the insecticide. There were no differences in fenitrothion...

More Information
Summary:Two streams were sprayed with fenitrothion, one with an aqueous formulation and the second with an oil-base formulation, and water, sediment, plant and invertebrate samples were taken downstream to examine the partitioning and persistence of the insecticide. There were no differences in fenitrothion concentration with depth or between midstream and slow water for either formulation. Fenitrothion was rapidly taken up by suspended matter and the organic fraction of sediments. High concentrations were found in most plants and insects sampled with the highest persistent levels being found in the leafy liverwort Jungermannia sp.
