Accounting for Metal Bioavailability in Assessing Water Quality: A Step Change?
Leading peer-reviewed journal in the field of environmental science, Environmental Toxicology and Chemistry (ET&C) has published a paper that argues the case for bio-availability based environmental risk assessment approaches. The paper is authored by Dr. Chris Schlekat (from the Nickel Institute’s science arm, NiPERA) and Graham Merrington and Adam Peters (wca environment ltd) who are recognised experts in the field.
The paper illustrates the fundamental need for bioavailability normalization in environmental risk assessment of metals, tracks the evolution of global regulatory approaches for performing bioavailability normalization, and presents approaches for the implementation of these approaches that are both scientifically robust and practical. The emphasis of the paper is on multi-metal concepts and approaches, and includes a case study on the derivation of the Nickel Environmental Quality Standard under the Water Framework directive as an example of the normalization process.
