Risk assessments have included environmental pollutants such as PFOS, PFOA and perchlorate as well as substances produced via drinking water treatment such as disinfection by-productsThe National Centre for Environmental Toxicology (NCET), a specialised team within WRc, includes a group of dedicated toxicologists experienced in human hazard and risk assessment. It offers expert opinions on the likely and potential health risks posed by the exposure to chemicals in the environment and the work place.

Much of the work of the toxicologists involves the assessment of data, the maintenance of a rolling database of over 580 chemical Toxicity Datasheets for the water industry, and the derivation of environmental toxicological limit values (e.g. Human Health Criteria Values).

NCET has direct experience of R&D and regulatory toxicology relevant to the pharmaceutical, chemical, agrochemical, water, environmental health and retail industries.
