Toxicity studies and environmental impact assessment. [Effects of mercury pollution on crab populations in estuarine ecosystems]
There is abundant evidence that many factors can influence the toxicity of a particular pollutant including environmental fluctuations, season of the year, stage in life cycle, size, and sex. All of these factors should be assessed before making a judgment of the effect on natural populations. Such an assessment can be conceptualized using a simple population model through which control gates operate as functions of 1) the direct self-maintainance feedback from existing adult population biomass and 2) the recruitment of new individuals due to the maturation of larvae. By extracting general principles of organismic response to pollutants it is possible to incorporate the information into large-scale ecosystem models which would serve as working tools for answering environmental decision-making problems.
