Harlan Laboratories has extensive experience in performing bacterial toxicity and biodegradation tests on industrial chemicals, agrochemicals, biocides, and more recently, on veterinary medicines and pharmaceutical products. Studies are performed according to the international test guidelines of OECD, EU, EPA/OPPTS, ISO and JMAFF.
With modern, purpose-built facilities Harlan Laboratories’ environmental science team offers a one-stop solution to all your ecotoxicological testing requirements.
Tests conducted within Harlan Laboratories include, but are not limited to:
Bacterial Toxicity
