| 제목 | Contemporary organic contamination levels in digested sludge from industrial wastewater treatment plants : Polycyclic aromatic hydrocarbon |
| 초록 | The 16 priority PAHs(Polycyclic aromatic hydrocarbons) designated by US Environmental Protection Agency were analyzed for some digested sludge from industrial wastewater treatment plants in Korea. PAHs are an important group of organic contaminants present in the sludge due to their persistence and toxic potential. Therefore, characterization of PAHs in the sludge is required to develop environmentally sound management. PAHs were extracted from freeze-dried sludges using methylene chloride : methanol (2 : 1) mixture in a soxhlet extractor. The extracts were cleaned-up by silica gel/alumina combination column and subsequently were fed into Gas Chromatograph/Mass Spectrometer(GC/MS) for determination PAH contents. PAHs contents of sludge in Korea were compared with those in other countries. |
