Comprehensive GLP-regulated Ecotoxicology Services

Environmental toxicity studies play a critical role in understanding the potential risks and hazards associated with various compounds. It also facilitates protection and preservation of ecosystems, promote sustainable practices, and safeguard human and environmental health. At Intox, we provide a comprehensive range of environmental toxicology and ecotoxicology studies to determine threshold toxicity concentrations of a range of test compounds. Our teams of qualified and experienced environmental chemists provide integrated approach to ecotoxicity and environmental risk assessments, delivering high quality reliable results to meet the needs of the global industry and environmental regulators. With end-to-end capabilities to support advance ecotoxicology and analytical chemistry techniques using a wide variety of species and a track record of successful regulatory submissions, we can offer customized study protocols to meet the clients’ requirements.

Comprehensive array of ecotoxicology services at Intox:


In order to meet the regulatory requirements for agrochemicals, industrial chemicals, and human and veterinary pharmaceuticals, comprehensive aquatic ecotoxicology data plays a vital role in Environmental Risk/Impact Assessments (ERA and EIA). Intox provides a diverse range of aquatic ecotoxicology tests, encompassing the following:

  • Growth Inhibition Test (Algae: OECD-201)
  • Acute Immobilisation Test (Daphnia magna:
  • Fish, Acute (Guppy,carp, Zebrafish: OECD-203)


Diversity of terrestrial organisms – plants, invertebrates, and vertebrates – living in and on the soil makes hazard assessment of a chemical on a terrestrial environment critical and more complex. Our terrestrial ecotoxicology tests include

  • Avian (Dietary, Acute oral: OECD-205/223)
  • Earthworm (Acute: OECD-207, Reproduction:
  • Subchronic Toxicity Test (Earthworm:
  • Honeybee Acute Toxicity (Oral: OECD-213,
    Contact: OECD-214)
  • Nitrogen Transformation Test (Soil Microorganisms: OECD-216)
  • Carbon Transformation Test (Soil Microorganisms: OECD-217)
