Abstract/Summary

Globally pesticide use has been associated with negative impacts on riverine invertebrate communities, but chronic exposure effects to most specific groups of pesticides are not well understood. In this paper, we sought to identify invertebrate species most vulnerable to effects of AChE-acting pesticides in UK rivers for potential application in environmental monitoring. We did this using a combination of the conservation of molecular target for AChE-acting pesticides (identified using the SeqAPass tool), laboratory-based toxicity data, and both biological traits and life history information. We then applied this information to assess for evidence of impacts on these riverine invertebrate communities in the Anglian region of England where there is high pesticide use. Sensitive genera to AChE-acting pesticides included Aedes, Anopheles, Cloeon, Ischnura, and the tolerant genera were Culex, Daphnia, Lymnaea. Using the UK Environment Agency's biota monitoring data spanning over period of 28 years (1984–2011) we evidence absence of the taxa most sensitive to AChE-acting pesticides (Ischnura, Aedes and Anopheles) but presence of AChE pesticide tolerant taxa (Lymnaea) at riverine sites in the Anglian region with high AChE pesticide use.
