Abstract
ABSTRACT: Octachlorostyrene(OCS) has been persisted in environment because it has not been decomposed easily. And, it has been known as highly toxic compounds to the environment and human as well as accumulated as high concentrations in a biota through a food chain. Therefore, OCS was monitored for water, soil and fish sampled from the areas where were able to be contaminated with OCS. The recoveries of octachlorostyrene were 93.1 ∼ 98.6% in water, 90.4 ∼ 94.8% in soil and 81.5 ∼ 90.2% in fish and detection limits were 0.0004 mg L -1 for water, and 0.002 mg kg -1 for soil and fish, respectively. OCS was not detected in water, sediment, soil and fish samples from Ulsan, Yeosu, Daejeon and Sihwa industrial complex and in soil sampled nearby incineration plants in all parts of the country. Accordingly, we estimated that there is no risk from exposure of OCS.Key Words: Octachlorostyrene, recovery, risk, exposure 209 * 연락저자:Tel: +82-42-821-6735, Fax: +82-42-821-5781E-mail: kslee@cnu.ac.kr
