Aquatic Ecotoxicology

All of our Aquatic Toxicology Testing is available with full GLP compliance.


Tier 1

  • Algal Growth Inhibition Tests (OECD 201) using green algae, diatoms and cyanobacteria.
  • Aquatic Plant Growth Inhibition Tests using Lemna sp. (OECD 221), Myriophyllum spicatum (OECD 238/239)
  • Invertebrate testing using Daphnia magna, acute(OECD 202) and reproduction (OECD 211) including male induction where necessary.
  • Invertebrate testing using Chironomus riparius (OECD 218/219), also acute (OECD 235) and full life cycle tests (OECD 233).
  • Fish testing with a range of species as listed in OECD guidelines, including acute (OECD 203), Early life stage (OECD 210) and Bioaccumulation (OECD 305).
  • Tests can be designed to meet EPA guidelines instead of, or as well as, the OECD guidelines.

Tier 2

  • Tests that address particular concerns or information gaps using additional aquatic plant, invertebrate or fish species to support the development of Species Sensitivity Distributions (SDD) or the Geomean approach.
  • Refined Tier 1 tests, adapted to resemble pulsed exposures reflecting realistic to worst case scenarios.
  • Expertise in testing to assess the potential for endocrine disruption in fish, e.g. biomarkers and/ or reproduction tests (OECD 229/230) and the sexual development test (OECD 234), should this be a consideration in your Environmental Risk Assessment.

Coming Soon - Tier 3 Environmental Risk Assessment using Model Ecosystems (Mesocosms).

  • Access to flexible flow-through ditch/stream/pond mesocosm facilities designed with the ability to simulate realistic to worst case pulsed exposures of aquatic communities.
  • Assessments can include the Ecological Threshold and Ecological Recovery Options.
