Accumulation of aromatic hydrocarbons and their derivatives in large water bodies generally occurs through processes, such as atmospheric deposition, surface runoff, etc. One of the anthropogenic sources might be drainage waters, especially in a city where city dwellers use various aromatic compounds in different forms for their comfort. This study proves the utility of liquid-liquid extraction through longtime mechanical agitation in order to extract aromatic compounds from water of a city drainage basin. The efficiency of this process of extraction was determined with the help of high performance liquid chromatography, which is found to be as high as 90.75% in case of selected hydrocarbon-fluoranthene. Gas chromatography mass spectrometry has shown that experimental water sample from various spots of waterbody contains a good number of identical aromatic compounds. Some of them are esters of phthalic acid. Apart from being petroleum and coal origin, there are lots of modern amenities used by city residents of which these aromatic substances are either constituents or derivatives.
