Aquatic Ecotoxicology
CEMAS carries out a range of GLP-compliant aquatic studies, using species including plants and invertebrates to evaluate ecotoxicological effects in support of the registration of substances. The Aquatic Ecotoxicology Unit has recently constructed laboratories and all studies are carried out with stringent environmental control where temperature, humidity and photoperiod can be regulated. In-house culturing and holding facilities provide quality organisms for a range of tests.
CEMAS has a fully equipped analytical facility, with dedicated analysts providing support to aquatic studies, including method development, method validation and water and tissue sample analysis.
The complete acute package of aquatic toxicity studies conducted to OECD (201, 202 and 203), EPA (OPPTS), EEC and JMAFF Guidelines are available on site, in a suite of modern facilities. Many test species are available including:
- Daphnia magna (water flea)

- Chironomus riparius (non-biting midge)
- Algal species including:
- Pseudokirchneriella subcapitata
- Skeletonema costatum
- Navicula pelliculosa
- Anabaena flos-aquae
- Lemna gibba and Lemna minor (duckweed)
Many prolonged tests are also regularly conducted including reproduction and growth tests. Other species and Study types are available on request.
CEMAS has over 15 years of experience of conducting ecotoxicology studies. CEMAS staff members are highly motivated individuals with a raft of experience in conducting a range of studies to internationally recognised testing guidelines. Study Directors are dedicated to developing and maintaining relationships with clients throughout the life of projects to ensure delivery of quality data on time.
