Aquatic Ecotoxicology



Fera offers a full package of studies to GLP on aquatic non-target organisms, on microorganisms and ready biodegradability tests. The potential toxic effects of Plant Protection Products (PPPs), chemicals and metabolites on algae and aquatic macrophytes are examined using different types of study designs in accordance with current OECD and EPA guidelines, covering the requirements for the registration of plant protection products (PPPs) and veterinary medicines. 

All studies are planned and performed by an experienced team of scientists and technical personnel, with the analytical dose verification and fate of the active ingredient(s) is performed as close as possible in parallel to the biological part of the study. We can also adapt our services to provide bespoke tests that meet your specific data requirements. 

"Our routine tests can be adapted to suit your particular data requirements"


Fera has the best people in the right place focussed on delivering the right solution. We continuously invest in our people and support them in delivering the best science to our partners.
Gordon Turnball

Gordon Turnbull

Gordon works on the detection and measurement of herbicide, pesticide, veterinary medicine and other chemical residues.  As a GLP study director, Gordon has conducted a wide range of studies including method development and validation, the analysis of crops and animal tissues, and environmental risk assessment studies using both radiolabelled and non-radiolabelled chemical substances.

Steve Mattock

Steve is the Head of the Ecotoxicology group at Fera. Steve has over 22 years practical experience of conducting ecotoxicology studies in both industry and contract research laboratories. In addition, he has also spent over 15 years working as an environmental risk assessor preparing ecotoxicology risk assessments for plant protection products, biocides and REACH related registrations.

Karen Thorpe

Karen Thorpe

Karen is an aquatic biologist based in the Ecotoxicology group at Fera. Her role is to deliver high-quality aquatic ecotoxicology studies and she has over 20 years practical experience of working with aquatic organisms in an ecotoxicological setting. Karen has been involved in the development of methodologies for assessing the effects of chemicals on reproductive physiology and will be responsible for expansion of the science capabilities within the group to evaluate chemicals for endocrine disruption.

By Sector : Environmental Risk Assessments

Plant protection products

Plant Protection Products (PPP)

Fera has over 30 years’ experience working with international partners, helping them develop effective, sustainable, and safe chemical products that minimise ecosystem impact and pollution. Our goal is to provide you with high quality endpoints for the registration of your crop protection product. As your partner we offer you access to state-of-the-art facilities and a leading team of expert ecotoxicologists who can deliver studies appropriate to your needs, across global regulatory frameworks. Find out more.

Veterinary medicines

Veterinary Medicines & Feed Additives

Ecotoxicology studies are required by most of the major regulatory authorities to assess the potential hazards posed by veterinary medicines when released into the environment. Consideration must be given to whether the veterinary medicine is a natural substance, the use of which will not alter the concentration or distribution of the substance in the environment. Will the it be used only in non-food animals, etc. Fera offers a full package of studies to GLP on aquatic non-target organisms tests and are planned and performed by an experienced team of scientists and technical personnel. Find out more.

Bespoke Aquatic Studies

Bespoke Studies

We can also adapt our services to provide bespoke tests that meet your specific data requirements.  

Using our state of the art new aquatic laboratory which provides 13 test rigs housed in three holding rooms with programmable temperatures and lighting regimes.

All studies are planned and performed by an experienced team of scientists and technical personnel, with the analytical dose verification and fate of the active ingredient(s) is performed as close as possible in parallel to the biological part of the study. Why not get in touch to discuss your specific requirements.
