title: Proteomics as a route to identification of toxicity targets in environmental toxicology.
abstract: Ecotoxicology describes a three-way relationship between ecosystems, chemical pollutants and living organisms. It is predicated on the fact that chemical pollution can exert toxic effects on organisms at the individual and population levels. These toxic effects may provide important information to supplement chemical analysis of environmental samples and aid in assessing the environmental quality of specific ecosystems. Traditionally, effects have been detected by means of biomarkers which, of necessity, were often molecules or processes known to be affected by pollutants. Proteomics provides a means of achieving high-throughput analysis of effects on protein populations and sub-populations with the potential to identify novel biomarkers. This review summarises the main approaches currently used in this area and assesses the potential of proteomics for identification of novel toxicity targets.
