Ecotoxicology & Risk Assessment

Our ecotoxicologists support a wide range of services to determine risks to wildlife and the environment including aquatic and terrestrial study design, ecological modeling and risk assessment, endangered species strategy and risk assessment, placement and monitoring of regulatory studies, and expert advice on product registration packages. Members of our team have served as study directors on laboratory, semi-field and field ecotoxicology studies, having direct experience with research and risk assessments involving non-target aquatic and terrestrial organisms.

In North America, we have significant organism-specific expertise and work closely with clients on diverse projects dealing with pollinator issues, avian & other vertebrate wildlife topics, and aquatic vertebrate & invertebrate topics.

In Europe, we have extensive experience of ecological risk assessments to support plant protection products, biocidal products and industrial chemicals (REACH) registrations.
