• Ecotoxicology Testing

    The ecotoxicology portfolio offers a comprehensive range of marine and freshwater acute and chronic toxicity tests, bioaccumulation and biodegradation studies, which assess environmental risk of chemicals and waste water discharges. This can be performed as Whole Effluent Toxicity (WET) testing or as an individual chemical component to determine the specific chemical toxicity profile. Our tests operate at 3 trophic levels.

    All testing is conducted to the principles of Good Laboratory Practice (GLP) and ISO 9001 accreditation. We pride ourselves on rigorous quality control, assuring you our results are trust-worthy and reliable. Our portfolio of tests follow standardized protocols according to OSPAR, OECD, ISO, ASTM.

    Description

    We uniquely culture our own algae, crustaceans and fish stocks, ensuring we always have a constant supply of healthy organisms. Our water system incoming from a local site, Scapa Flow, undergoes a stringent treatment process. Therefore, we have a continual supply of clean water which creates optimal conditions to conduct tests.
