Aquatic Ecotoxicology Testing

Comprehensive aquatic ecotoxicology data is necessary for regulatory submissions in a range of industries, including agrochemicals and industrial chemicals. They may also be required in the submission of Environmental Risk/Impact Assessments (ERA and EIA) for both human and veterinary pharmaceuticals.

Blue and silver zebrafish used in aquatic toxicity studies.Our scientists have a deep and extensive knowledge of not only the regulatory aspects but also the design and conduct of aquatic ecotoxicology studies and programs.

Our comprehensive portfolio includes studies to assess the toxicity of test articles to a range of species and all our aquatic ecotoxicology testing is fully supported by our integrated analytical services for the method validation and routine analysis.

Aquatic Ecotoxicology Studies

  • Activated sludge respiration inhibition (OECD 209)
  • Algal growth inhibition (freshwater and marine) (OECD 201)
  • Acute and prolonged toxicity to Daphnia magna (OECD 202, OECD 211)
  • Acute (96-hour) and prolonged toxicity to cold- and warm-water fish (e.g., rainbow trout, bluegill sunfish, carp, fathead minnow, and zebrafish) (OECD 203)
  • Fish embryo toxicity test (FET test) (OECD 236)
  • Fish, toxicity test on egg and sac-fry stage (OECD 212)
  • Fish early life stage (OECD 210)
  • Radiolabeled (or cold) bioaccumulation and/or metabolism in fish (OECD 305)
  • Lemna sp. growth inhibition (OECD 221)
  • Acute and prolonged sediment water toxicity test to Chironomus riparius (OECD 235, OECD 218, OECD 219)
  • Sediment-water toxicity test with Lumbriculus (OECD 225)

Frequently Asked Questions (FAQs) about Ecotoxicology Testing

  • What aquatic ecotoxicology studies are required to register an agrochemical product?

    You may need a range of aquatic ecotoxicology studies in your program to assess the general adverse effects of your product (AI and formulations) on ecosystems, depending on the registered uses of your product and the type of active (e.g., pesticide or chemical). The studies will include assessing the effects on aquatic organisms (algae and higher plants) and the potential for groundwater contamination by the active or its metabolites.

  • How should I assess the ecotoxicity of my pesticide?

    You may need to perform a range of different studies. The exact program design will depend on several factors, including the class of active substance, the stability of the formulation, and the metabolites formed, amongst others.
