摘要: Trace organic contaminants in deep-sea sediments near Dokdo were analyzed. Total PAMs concentration ranged 14.8-314 ng/g dry weight and high molecular PAHs dominant. The highest was detected at A19 which located Ulleung Basin. Most of organochlorines under detection limit. Among the organochlorines, DDT compounds dominant followed by HCHs HCB. Butyltin most organophosphorus pesticides not detected. Vertical distribution showed typical sub-surface maximum decreasing trends depending on depth. reached 454ng/g. Some DDT, HCH also trends. Other target pollutants core sediments. Abnormally level discussed input sources inferred to be transport sludge derived pollutant dumped dumping site 'Byung' deep current.
