Standard Guide for Determination of the Bioaccumulation of Sediment-Associated Contaminants by Benthic Invertebrates

Importancia y uso:

5.1 Sediment exposure evaluations are a critical component for both ecological and human health risk assessments. Credible, cost-effective methods are required to determine the rate and extent of bioaccumulation given the potential importance of bioaccumulation by benthic organisms. Standardized test methods to assess the bioavailability of sediment-associated contaminants are required to assist in the development of sediment quality guidelines (1, 2, 3)5 and to assess the potential impacts of disposal of dredge materials (4).

5.2 The extent to which sediment-associated contaminants are biologically available and bioaccumulated is important in order to assess their direct effects on sediment-dwelling organisms and assess their transport to higher trophic levels. Controlled studies are required to determine the potential for bioaccumulation that can be interpreted and modeled for predicting the impact of accumulated chemicals. The data collected by these methods should be correlated with the current understanding of toxicity or human health risks to augment the hazard interpretation for contaminated sediments.
