Abstract : The success of laboratory bioassays as diagnostic tools for assessing the effects of environmental perturbations has been limited. It is proposed that the adenylate energy charge coupled with analysis of selected metabolic enzymes may overcome some of these limitations. The adenylate energy charge can be calculated from concentrations of three adenine nucleotides: ATP + 0.5 ADP/ATP + ADP + AMP. Several studies demonstrate that the energy charge can be a gauge of environmental impact of importance to the survival of particular species. Insights as to the cause of impacts on the biota from complex mixtures such as dredged material may be gained from analysis of test organisms for selected metabolic enzymes.
