Our capabilities

The purpose of ecotoxicology testing is to predict the effects of pollution, so that the most efficient and effective actions can be identified to prevent or remediate any detrimental effects.

Our multidisciplinary team of scientists have substantial experience across multiple vertebrate and invertebrate species and in a variety of test systems, (static, flow through, pulsed dose, in marine and freshwater environments). The team comprises proven experts in testing routine and problematic (hydrolytically unstable, highly sorptive, volatile, low solubility) materials and regularly develop novel methodologies, exposure systems and culture techniques to support bespoke testing strategies. We operate in modern GLP-compliant facilities striving to provide the highest quality service possible.

Our facilities

We have state of the art facilities including in-house freshwater and seawater processing and management systems, controlled temperature rooms, high flow through rates. Direct access to clean seawater provides highly flexible and customizable resources for your research project.

Flow through system design

-Most longer term fish studies are run under flow through conditions, to maintain optimum oxygen levels and to maintain the stability of dose concentrations.
-Daphnia magna and invertebrate studies can be run using a flow through design.
-The semi static design refers to solution renewals typically daily where the compound is unstable.
