This study presented data about concentrations of BTEX (benzene, toluene, ethylbenzene and o-, m-, p-xylenes) and PAH (poly aromatic hydrocarbons) in water samples of Patoku Lagoon. Fifteen water samples were taken in different stations of lagoon in October 2013. Headspace solid phase micro extraction (HS-SPME) technique was used to trace BTEX in water samples. For isolation of PAH liquid-liquid extraction assisted with Dichloromethane as extraction solvent were used. 1 L water samples were taken for each stations of Patoku Lagoon for PAH analyze. The analysis of BTEX and PAH in water samples was performed by gas chromatography technique using flame ionization detector (GC/FID). Injections of BTEX were done in injector PTV directly by using Head-Space mode of Polydimethyl Siloxane fiber. 1 ul extract in Dichloromethane (extracting solvent) were injected for PAH analyses. VF-1ms capillary column (30 m x 0.33 mm x 0.25 um) was used for separation of BTEX and PAH compounds. Relatively high concentrations of BTEX and more volatile PAH compounds were detected in water samples of water samples of Patoku Lagoon. The presence of volatile organic pollutants could be mostly of automobilist transport near the lagoon, water currents and discharge of industrial wastes in Mati River. [ABSTRACT FROM AUTHOR] |
