REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals)

  • Work with a partner who has extensive experience of undertaking laboratory studies to support the registration of chemicals under REACH. Our capabilities range from acute toxicity and biodegradation testing to performing complex higher tier studies.

REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals)


The REACH regulation was adopted by the EU (EC 1907/2006) to improve the protection of human health and the environment from the risks posed by chemicals. As such, the regulation covers the manufacture, import and use of chemicals. In principle, REACH applies to all chemical substances, and therefore not only covers industrial chemicals but also household chemicals, such as cleaning products, as well as substances used in clothes, furniture and electrical appliances. All chemicals manufactured or imported in quantities greater than 1 tonne per year must be registered.

In the EU, REACH is administered by ECHA (European Chemicals Agency), whilst in the UK, REACH submissions under the UK REACH regulation are regulated by CRD (Chemicals Regulation Division) within the Health and Safety Executive. 

REACH places the responsibility for managing chemical safety on industry and companies must therefore identify and manage the risks of substances they manufacture and market in the EU and UK. As part of the REACH process, registrants must demonstrate how their substances can be used safely and if the risks cannot be managed, then the use of the substance can be restricted. REACH targets the progressive substitution of the most dangerous chemicals ("substances of very high concern") with suitable, less hazardous, alternatives. Additionally, REACH aims to minimise testing on animals by requiring companies to share data and promoting alternative, in-vitro (non-animal) methods for exploring chemical properties. 

How can we help?

Under REACH, chemical manufacturers and importers are required to gather information on the properties and hazards of their chemical substances. If the substance is imported or manufactured in quantities greater than 10 tonnes, then a chemical safety report is also required as part of the registration. A key aspect of this assessment is understanding the potential effects of the chemical substance on the environment.

Fera is vastly experienced at assessing the impact of chemicals on the environment. Our expertise can therefore support REACH compliance by undertaking studies that explore the following properties of chemical substances:

Environmental Fate and Behaviour in the Environment

  • Degradation
  • Environmental distribution
  • Bioaccumulation


  • Effects on Aquatic Organisms (including sediment)
  • Effects on Terrestrial Organisms
  • Microbiological Activity in Sewage Treatment Systems

Endocrine Disruptors (EDs)

Endocrine disruptors (EDs) are chemical compounds which can alter the normal functioning of the endocrine system and cause developmental and reproductive effects in humans and animals. As both the exposed individual and its offspring can be affected by endocrine disruption there are concerns about the longer-term impacts of endocrine disrupting chemicals for populations and ecosystems.

A diverse array of organic chemicals have been shown to exhibit endocrine disrupting effects, including polychlorinated biphenyls (PCBs), organochlorine pesticides, plasticizers, surfactants, pharmaceuticals, natural and synthetic estrogens as well as phyto- and mycoestrogens. Many of these compounds can alter activity of the endocrine system at orders of magnitude below concentrations previously thought to be harmful to humans and animals, therefore posing a major challenge to the regulation and use of many classes of chemical.

Our Study Director and Aquatic Ecotoxicologist, Karen Thorpe, is an applied biologist who has worked in the field of endocrine disruption for over 20 years. Karen understands the impacts of endocrine disrupting chemicals on stress physiology and the reproductive success of invertebrates and vertebrates, particularly fish, and has extensive experience of performing laboratory studies to explore the effects of chemicals on the endocrine system.
