Abstract

Surface sediments from 35 sampling sites of the Sea of Marmara were analyzed for 6 phthalate acid esters (PAEs), namely diethyl phthalate (DEP), dimethyl phthalate (DMP) di-n-butyl phthalate (DBP), benzylbutyl phthalate (BBP), di-(2-ethylhexyl) phthalate (DEHP) and di-n-octylphthalate (DnOP). In all samples, concentrations of the DBP and DEHP were found to be higher than the other four PAEs. DBP and DEHP concentrations in sediment samples ranged from <MDL to 1.18 μg/g dry weight (dw), and 0.01 to 4.52μg/g dw, respectively. The analytical results showed a direct relation of PAEs levels with the input of urban and industrial treated waste waters near the sampling point. As compared to the results from other studies, the Sea of Marmara exhibited relatively low pollution by the PAEs.
