Abstract

Ciliwung is one of important and big rivers running from West Java Province to Jakarta Bay. Rapid development accompanied by high industrialization, enormous population growth, and increasing number of vehicle has increased hydrocarbon pollution risk. Polycyclic aromatic hydrocarbons (PAHs), one class of hydrocarbons, have an adverse effect on human health due to their high toxicity, mutagenic, carcinogenic and persistent in the environment. The main objectives of this study were to identify and quantify of sedimentary PAHs of Ciliwung River in Jakarta. Freeze-dried sediment sample was extracted with a pressurized fluid extraction, purified by two-step of column chromatography, and concentrated by rotary evaporator. Extract was identified and quantified by gas chromatography-mass spectrometry (GC-MS). The result showed relatively abundant alkyl PAHs, and a considerable amount of high molecular weight PAHs, suggesting the input of both petrogenic and pyrogenic sources. Concentration of PAHs detected ranged from 69,6 to 1415 ng/g where a total concentration of PAHs was 10.196 ng/g. The high concentration of PAHs is one indicator of organic pollutants in Ciliwung River.
