Abstract

Rapid development in the past few decades accompanied by enormous population growth and increasing numbers of vehicles has caused severe environmental pollution, with organic micropollutant being one of the results. Concerns have been raised about organic micropollutants such as polycyclic aromatic hydrocarbons (PAHs) due to their toxicities, mutagenic, carcinogenic and persistence. This study investigated on the distribution and source identification of sedimentary polycyclic aromatic hydrocarbons (PAHs) in the aquatic urban environment in Jakarta. Freeze-dried sediment sample was extracted by pressurized fluid extraction, purified by two-step of column chromatography, and concentrated by rotary evaporator. Extract was identified and quantified by gas chromatography-spectrometry mass (GC-MS). Polycyclic aromatic hydrocarbons (PAHs) were analysed from sediments collected of 13 rivers that run through Jakarta City. High concentrations of PAHs (1992-17635 ng/g-dw) were observed at all sampling locations. Ratios of alkylated PAHs to parent PAHs exhibited both petrogenic and pyrogenic signatures with predominantly petrogenic inputs. High hopanoid concentrations (4238-40375 ng/g dry sediment) supported the petrogenic input to Jakarta’s rivers. The high concentration of PAHs is indicator for organic pollutant in the aquatic urban environment in Jakarta.
