REVIEW OF AQUATIC ECOLOGICAL RISK ASSESSMENT: PAST, PRESENT AND FUTURE.
 
Ecological risk assessment is a methodology for quantifying the likely adverse response of a system or systems to some form of human impact. In principle it ought to be expressed in terms of likely reduction in population density, species extinctions and impairment of ecosystem processes, but very often is expressed as more naive indices that are based upon laboratory ecotoxicological observations. This paper will critically review these approaches and compare and contrast how they are being used in North American and European risk management legislation. The historical precursors of these kinds of approaches in terms of both suspicion-based and hazard-based methods of evaluating adverse ecological impacts will be briefly described. Likely future trends, taking into account pressure from environmental groups and the need for stakeholder involvement, will be outlined.
