Fresh Water Fish


Ecotoxicology is the study of the effects of toxic chemicals on biological organisms, and is essential for evaluating the effects of industrial processes on the environment. Bureau Veritas operates three dedicated ecotoxicology laboratories in Canada. Our team of experts has experience conducting toxicity testing using more than 25 different species of bacteria, algae, plants, invertebrates and fish. Our goal is to be your first choice for both routine and customized toxicity testing programs for evaluating effluents, sediment, soil, and chemical substances.

Effluent Discharge from a Factory Pipe

Acute & Sublethal Tests

Bureau Veritas offers fresh water and marine toxicity tests for effluent discharge compliance as well as monitoring programs for environmental effects. Toxicity tests are conducted in accordance with the relevant Environment Canada, US EPA, or OECD/OCSPP methods.

Fresh Water Lake

Fresh Water & Marine Testing

Bureau Veritas provides effective tools for assessing toxicity sources associated with marine and fresh water sediments. We have considerable experience in testing sediments from contaminated sites, dredged sediments slated for disposal at sea, and determining the bioaccumulation potential in dredged sediments.



Toxicity Identification Evaluation (TIE) and Toxicity Reduction Evaluation (TRE) are used when clients need to identify and remove the toxic components in a chemical mixture such as an effluent. Analyzing and eliminating these toxins ensures a healthier ecosystem for fish and other aquatic species, as well as preventing these from being passed down the food chain.
