Comparison of Three Lipid Extraction Methods

摘要

Organism lipid content is a critical component of both theoretical bioaccumulation potential, currently recommended in the 'Green Book' (U.S. Environmental Protection Agency/U.S. Army Corps of Engineers 1991), and the sediment quality criteria (SQC) proposed by the USEFA. Since no standard extraction method exists for quantitating lipids, many different methods are used, leading to questions concerning the comparability of lipid data obtained using different extraction methods. Research examining the relationship between various extraction methodologies can help reduce uncertainty in interpreting and utilizing data obtained from different studies, leading to better environmental assessments concerning the long-term effects of dredging.
