Assessing the toxicity of environmental samples

Our multi-disciplinary ecotoxicology team of biologists, ecologists and chemists analyse toxic substances present in groundwater, shellfish, fish, sediment, leachate and wastewater. They can also identify what the ecological risks are for plants, invertebrates and biological communities exposed to those toxins.

Their expertise can be applied to both commercial and research situations.

Our ecotoxicology services include:

  • acute and chronic tests for direct toxicity assessment (DTA) of individual contaminants, or more complex mixtures and samples (soil, water and sediments) from various sources (e.g. industrial, municipal effluent, outflows)
  • assessing the efficacy of treatment technologies and remedial activities that mitigate the negative effects of contaminants
  • assessing the long-term multi-generational risk of multiple stressors (a combination of physical and chemical stress resulting from human activities) using genetics and biochemical methods in plant and microinvertebrates models
  • tests using a wide range of methods to cover all integration levels (i.e. cellular (in vitro), physiological (in vivo), and whole organism responses) and at least three taxa and trophic levels (e.g. algae, mussel, copepod, fish)
  • chemical and product testing following the standards and guidelines established by organisations such as the OECD, Environmental Protection Authority (EPA), and American Society for Testing and Materials (ASTM). This means the results will also fulfil the requirements of the Australian and New Zealand Environment Conservation Council (ANZECC) Guidelines for Fresh and Marine Water Quality and Maritime New Zealand recommendations.
