Understanding the risks of chemicals to the environment and human health often requires data on “exposure” to be either directly measured or estimated using an appropriate model. We have extensive experience with a range of environmental models, including those required to • Assess the bioavailability of metals • Develop exposure assessments for substances entering the environment from various sources
