Environmental Fate & Degradation Services
The Environmental Fate team at Brixham are a dedicated team of expert scientists who concentrate on evaluating the partitioning and degradation behaviour of test substances in environmental compartments.
We have a well-earned reputation for delivering high quality data in a variety of industry sectors, including; pharmaceutical, agrochemical and petrochemical companies. We regularly provide support for customers requiring guidance on REACh, EPA, FDA, EMEA and OECD regulations.
Our team has extensive experience in delivering a comprehensive range of studies to a variety of international test guidelines. Please see Our Services for more details. The team has a high-tech radiochemistry laboratory, and routinely performs studies with radio-labelled test substances.
We are eager to tackle novel or challenging studies, and have substantial knowledge of working with difficult test substances. We are keen to collaborate with our clients to provide innovative solutions to fulfil their more demanding testing requirements.
