Distribution of Siloxanes in sediment from Korean special management sea areas

摘要

Siloxanes are a polymeric organosilicon compound in which silicon atoms bonded to oxygen atoms [Si-O] and methyl groups. The individual substances of the siloxanes have a cyclic (D-cyclic siloxanes) or linear (L-linear siloxanes) morphology depending on the molecular structure, strongly volatile and hydrophobic. Siloxanes widely used in consumer product such as electronics, personal care products, cosmetics and medical instrument. However, their persistence, toxicity and bioaccumulation properties concern about environmental problems. Several studies of siloxane’s effects were reported but still shortage thoroughly researching into behavior and distribution of siloxanes in the marine environment. In this study, the distribution characteristics of siloxanes in the sediment of the special management areas in Korea including Gwangyang Bay, Masan Bay, and Busan Port were investigated.
