Pesticides, biocides and medicines are important tools in crop protection, facility maintenance and disease control.

The Pesticides and Biocides Directives both aim to harmonise the European market and provide a high level of protection for humans, animals and the environment.

Recent EMEA and VICH guidance on environmental risk assessment of human and veterinary medicines now includes increased environmental data requirements when bringing medicines to market.

We have expertise in the environmental risk assessment of pesticides, biocides and medicines, including interpretation of higher tier tests (e.g. mesocosms) and use of probabilistic approaches. We have developed prioritisation frameworks for human and veterinary medicines and advised on environmental toxicology, monitoring and modelling strategies for government clients. We advise commercial clients when dealing with regulatory agencies and when preparing dossiers for marketing authorisation applications.

We have also advised UK Government on appropriate test frameworks for engineered nanoparticles.
