Quantifying toxic effects of chemicals on biological populations and communities

An understanding of toxic effects on biological populations is crucial for determining the long-term consequences of chemical pollution in the natural environment. But toxicity to organisms is usually expressed in terms of a short term ‘observable’ effect on individuals from which a summary endpoint is derived for risk assessment and environmental quality standards. Such estimates are therefore typically subject to high uncertainty. In this talk I provide recent illustrations of quantitative approaches and extrapolations made from laboratory studies to determine longer term toxic effects at population, community and intergeneration levels.
