environmental risk assessment 

Charles River’s Environmental Risk Assessment (ERA) service is based on European guidelines; however, it can be applied to other submissions in differing countries and regulatory agencies.

A Marketing Authorisation Application (MAA) for a new human pharmaceutical substance should be accompanied by an ERA, as outlined in European Union Directive 2001/83/EC. An ERA is conducted in two phases. 

Phase I calculates the Predicted Environmental Concentration in surface water (PECSURFACEWATER) of the active substance and relevant metabolites. If PECSURFACEWATER exceeds a set action limit, or if an expert evaluation of preclinical safety and ecotoxic potential suggests a possible environmental concern, then a Phase II environmental fate and effects analysis should be performed.

Phase II comprises two tiers:

  • Tier A – generation of a base set of laboratory data to assess physical-chemical properties, environmental fate, and aquatic effects of the substance
  • Tier B – extended evaluation of environmental fate and effects, triggered if Tier A results indicate a risk to the environment and may include bioaccumulation, sediment, and soil organism testing


We have experience in ERA for all industry product sectors, including human pharmaceuticals, comprising:

  • Full understanding of regulatory requirements from initial consultation and Phase I evaluation to the final ERA report
  • Tailored program and study design development to meet Phase II requirements
  • Liaison with appropriate regulatory authorities regarding detailed design on any applicable higher tier tests
  • Modern, flexible facilities capable of accommodating long-term tests, coupled with the latest analytical equipment to ensure the highest quality for all in-life and analytical study components
  • Capability to assess active substances with specific modes of action, such as endocrine disruptors, with on-site expertise in fish pathology and endocrinology
  • 20-year proven track record in environmental testing
