Abstract:
|
Despite more than 20 years of severe criticism, the No Observed Effect Concentration (NOEC) is the most widely used measure of toxicity in ecotoxicology. Coupled with the equally problematic concept of a Species Sensitivity Distribution (SSD), the NOEC is used to determine a 'safe' concentration for toxicants in animals and the receiving environment. These 'safe' concentrations are used in regulatory contexts as well as underpinning critical design decisions associated with major infrastructure projects such as de-salination plants, off-shore oil rigs and ocean outfalls. The core of the criticisms of contemporary ecotoxicological practice focus on the inadequacies and inappropriate use of classical modes of statistical inference. In this talk I describe an alternative Bayesian framework for estimating the No Effect Concentration (NEC) and inference for the Hazardous Concentration (HCx).
