Abstract
This study has been carried out to manage effectively 3 unregulated hazardous organic chemicals (PCBs, PAHs, HCB) in Korea. Total content characteristics of the organic chemicals have been investigated from 16 major hazardous industrial categories such as sludges, waste and mechanical oils, etc. The ranges of concentration of 7 PCBs isomers (IUPAC No. 28, 52, 101, 118, 138, 153, 180) and 7 PAHs substances in sludges, which can be dumped into a marine, are N.D ~ 0.429 mg/kg (dry base) and N.D ~ 82.75 mg/kg (dry base), respectively. Among PAHs, naphthalene concentration is detected the highest at coke/petrochemical industry and phenanthrene concentration exceeded 5 times on the 1st standard of Korean Ocean Dumping Act at primary metal industry. The range of HCB concentration, which is regulated in Stockholm Convention, is N.D ~ 0.274 mg/kg (dry base) and detected at chemical manufacturing industry, primary metal industry and the others equipment manufacturing industry.
