Abstract: Abstract Environmental fluctuations and biological variability affect the establishment of baseline data in studying the ecotoxic effects of pollutants. Since substantial fluctuations are recorded for various ecological indices, it becomes problematic to establish whether an observed change in some ecological parameters represents a variation caused by presence of a pollutant, or represents 'natural' fluctuations inherent in the ecosystem. Thus, ability to predict ecotoxic effect lies at the base of the diagnosis. Such diagnosis should employ characteristics that reflect the integrated response of component populations to perturbations and as well provide a comprehensive picture of ecosystem 'status'. Measurements become authentic and acceptable only when compared with normal values of the numerical parameter in question.
