Environmental Effects of Dredging. Lower Limits of Organic Carbon Normalization: Results of Fish/Sediment/Water Equilibrium Partitioning Studies,

Abstract

This technical note reports the initial results of studies measuring biota/ sediment/water equilibrium partitioning of a polychlorinated biphenyl (PCB) congener. The focus of this technical note is on the validity of normalizing concentrations of neutral organic chemicals on sediment total organic carbon (TOC) when sediment TOC concentrations are low. Over the past 10 years, the U.S. Environmental Protection Agency (EPA) has aggressively pursued development of single-chemical sediment quality criteria (SQC). Equilibrium partitioning of neutral organic chemicals between the organic carbon fraction of bedded sediments and the interstitial water of the sediments provides the theoretical basis for the most popular approach to development of SQC. The solution phase of the chemical in equilibrium with the sediment is considered to represent the bioavailable fraction and to enable the conversion of existing water quality criteria (WQC) into SQC or sediment quality standards. p1
