Concepts in Ecological Risk Assessment

Abstract

Assessing the risk of impact to natural ecosystems from xenobiotic compounds requires an accurate characterization of the threatened ecosystem, direct measures or estimates of environmental exposure, and a comprehensive evaluation of the biological effects from actual and potential contamination. Field and laboratory methods have been developed to obtain direct measures of environmental health. These methods have been implemented in monitoring programs to assess and verify the ecological risks of contamination from past events, such as hazardous waste disposal sites, as well as future scenarios, such as the environmental consequences from the use of biocides in antifouling bottom paints for ships.
