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.

wca are experts in the design and realisation of environmental and workplace monitoring programmes, as well as computation modelling approaches. We can advise clients on an appropriate cost-effective approach to meet their chemical exposure data requirements. We are also experts in the development and implementation of approaches for accounting for metal bioavailability during environment standard development and implementation.

Bioavailability of Metals

Metals are naturally present in the environment, but releases as a consequence of abandoned metals mines, industrial manufacturing, consumer uses, and recycling can pose risk to ecological quality.

Chemical Exposure Assessment and Modelling

Risk assessment is based on comparing a predicted exposure concentration to a predicted no effect concentration.
