Environmental Effects of Dredging. A Comparison of Three Lipid Extraction Methods.

Abstract

The role of lipids as the major compartment for neutral organic chemical partitioning in organism tissues has been well documented (Connell 1988; Esser 1986; Roberts, de Frietas, and Gidney 1977; Schneider 1982). Lipid normalization is used in the calculation of accumulation factors, which express the equilibrium distribution of neutral chemicals between sediments and aquatic biota (Ankley and others 1992; Ferraro and others 1990, 1991; Lake and others 1990; McFarland and others 1994; Young, Mearns, and Gossett 1991). A screening test used to estimate the bioaccumulation potential of neutral chemicals associated with dredged sediments relies on equilibrium partitioning to organism lipids (USEPA/USACE 1991). Additionally, the USEPA seeks to promulgate SQC that will require lipid normalization of data (USEPA 1993).
