A draft Scientific Criteria Document for the Development of Canadian Water Quality Guidelines for the Protection of Aquatic Life: Neonicotinoid insecticides for acetamiprid, clothianidin, imidacloprid, thiamethoxam and thiacloprid is available for public review and comment until May 28, 2020. The scientific criteria document is available in English and French.
Neonicotinoid insecticides (NNIs) are a group of pesticides commonly used in agriculture. Due to their high water solubility, NNIs are transported from agricultural lands to surface waters, where they have been detected with high frequency. The NNI mode of action has been shown to cause lethality as well as sub-lethal behavioural, growth and reproductive effects in aquatic life. Toxicity varies greatly, with invertebrate taxa, and particularly insects, showing higher sensitivity to NNIs than vertebrates.
