The presence of chemicals in the environment is often used as a measure of environmental impact. A drawback of this is that new or unknown environmental risks are overlooked. A possible alternative to measuring concentrations of chemical substances is to use biomarkers to examine the well-being of animals. Physiological and biochemical changes in organisms are often linked to the chemicals present in the environment. The Norwegian Environment Agency, in co-operation with EnviroPlanning, is studying which biomarkers are most suitable for environmental monitoring in different ecosystems.
The report for this study is available on the Norwegian Environment Agency’s homepage:
