摘要: This study presents the result of sewage pollution monitoring in sediments collected from 13 rivers that run through Jakarta city 2010 using linear alkyl benzenes (LABs) as molecular marker contamination. The surface samples were extracted by pressure liquid extraction, purified two-step silica gel column chromatography, and analyzed gas chromatograph (GC)-mass spectrometer (MS). clearly revealed high total LABs concentrations (6171-1559373 ng/g-dry weight) all sampling locations. I/E ratios (a ratio internal to external isomers LABs) ranged 0.9- 1.3, close raw sewage. with low showed are heavily affected untreated highlights urgently needed water treatment system Jakarta. Keywords : (LABs), marker,
