Occurrence of Azoxystrobin, Propiconazole, and Selected Other Fungicides in US Streams, 2005–2006

TL;DR: Fungicide occurrence appears to be related to fungicide use in the associated drainage basins; however, current use information is generally lacking and more detailed occurrence data are needed to accurately quantify such a relation.
Journal ArticleDOI

Glyphosate, other herbicides, and transformation products in midwestern streams, 20021

TL;DR: In this article, the authors document the occurrence of glyphosate and the transformation product aminomethylphosphonic acid (AMPA) in Midwestern streams and compare their occurrence with that of more commonly measured herbicides such as acetochlor, atrazine, and metolachlor.
Journal ArticleDOI

Is there a risk associated with the insect repellent DEET (N,N-diethyl-m-toluamide) commonly found in aquatic environments?

TL;DR: Risks to aquatic biota at observed environmental concentrations is minimal and data available was not sufficient to conduct a full risk assessment due to data deficiencies in source characterisation, transport mechanisms, fate, and ecotoxicity studies, warrant further investigation.

Glyphosate, Other Herbicides, And TransformationProducts In Midwestern Streams, 2002

TL;DR: The use of glyphosate has increased rapidly, and there is limited understanding of its environmental fate as mentioned in this paper, and there are limited understand of glyphosate's environmental fate, as it is highly water soluble and could be mobile in aquatic systems.
