Abstract

The species sensitivity distribution (SSD) has been an important development in ecotoxicology and, despite numerous concerns having been raised over many years, it remains the preferred (and often-times mandated) technique for establishing 'safe' concentrations of contaminants in receiving water bodies by jurisdictions around the world. Although universally recognised as a crucial pre-requisite for the statistical validity of the procedure, the assumption of random selection of species for SSD modelling is invariably violated. It has been shown in the present study that under very minimal assumptions, non-random species selection can result in HCx estimation errors of a factor of 20 or more...
