What is ecotoxicology?

Ecotoxicology is the study of the effects of chemicals on biological organisms, particularly at the ecosystem level. The goal 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.

If you are a company developing veterinary products or plant protection products (PPPs), it’s essential that you fully assess the risks posed by your products to the wider environment and natural ecosystems. In the face of ever-tightening regulation and restrictions on the chemical options available, Fera can help you to develop effective, sustainable products that minimise ecosystem impacts and pollution, while maximising the beneficial effects for crops, plants and animals.  With a heritage dating back decades and a combined wealth of experience of over 500 years, Fera has some of the industry's most reputable names in ecotoxicology,  evaluating the environmental safety of plant protection products, pharmaceutical and veterinary products on behalf of companies seeking registration. This includes investigating the selectivity of products against a range of pests and their usual enemies in the laboratory and the field. Specialising in the fate and effects of substances in the environment, our ecotoxicology specialists are able to respond rapidly to requests for complex, in-depth environmental studies, whether laboratory, field or semi field studies.

Regulatory Risk Assessment

Access to experienced senior scientists across all scientific disciplines, we understand the relevant legislative frameworks and are uniquely positioned to assist you meet the regulatory requirements for crop protection registrations.

As an internationally renowned centre of excellence, Fera is uniquely positioned to assess the biological effect of chemicals and effluent discharges on the  environment. In addition to working for and with government departments, Fera's ecotoxicology service provides services to a range of industrial sectors, including veterinary medicine, chemical manufacturers/suppliers, water industry and pharmaceutical. Working within the multi-disciplinary environment of Fera, our ecotoxicology team have the experience and expertise to offer a broad range of acute, chronic and bespoke ecotoxicology studies and related services. We have a proven track record of providing regulatory testing to Good Laboratory Practice (GLP) compliancy. 

 Fera's well-equipped laboratories house facilities to test a wide variety of species ranging from microbes to large fish, and include modern laboratories designed for performing flow-through experiments on freshwater and marine species. Our scientists have broad research experience and capabilities, and have been involved in setting up new international test guidelines for ISO and OECD. Our scientists use their expertise, combined with advanced resources and GLP-compliant laboratories, to assess the impact of your products on aquatic plants and animals, terrestrial non-target plants, insects and microorganisms, bees and other pollinators. We work in partnership with you to devise and conduct the appropriate tests to provide the essential data you need for robust environmental risk assessments.
