Short description: |
The report illustrates a scientific framework for assessing the risk of significant harm to an organism, animal or whole ecosystem on potentially contaminated sites. The framework demonstrates best practice in Ecological Risk Assessment (ERA), which plays an increasingly important part of the decision-making process for managing environmental problems.
|
Long description: |
The framework has four tiers of increasing complexity. The preliminary tiers help identify sites with potentially significant risks. The proposed framework has defined entry and exit points at each tier so that successive tiers are only used when necessary. To make a defensible decision about the potential risk of a site to the ecoreceptors present, the following data should be collated and assessed:
· chemical data on contaminants present, their form and concentration;
· biological data such as microbial, plant and invertebrate tests;
· ecological survey data on the extent and condition of populations and individual organisms of concern.
This combination of chemical, biological and ecological data (often referred to as a triad approach) provides a sound basis for decision making and site management
