Abstract: Over the past few years, the "critical body residue" approach for assessing toxicity based on bioaccumulated chemicals has evolved into a more expansive consideration of tissue residues as the dose metric when defining doseresponse relationships, evaluating mixtures, developing protective guidelines, and conducting risk assessments. Hence, scientists refer to "tissue residue approach for toxicity assessment" or "tissue residue-effects approach" (TRA) when addressing ecotoxicology issues pertaining to tissue (or internal) concentrations. This introduction provides an overview of a SETAC Pellston Workshop held in 2007 to review the state of the science for using tissue residues as the dose metric in environmental toxicology. The key findings of the workshop are presented, along with recommendations for research to enhance understanding of toxic responses within and between species, and to advance the use of the TRA in assessment and management of chemicals in the environment.
