Abstract

BPA mass fractions were determined in the sediments of 35 sites in the Adriatic Sea (channels, bays, open sea and city harbours) as well as in the suspended matter at the Kaštela Bay during 1999 to 2014 period. Sediment granulometric composition and content of organic matter and organic carbon were also analyzed. Mass fractions of BPA in sediments ranged between 1,05 μg kg-1 and 69,99 μg kg-1, and in suspended matter between 1,84 μg kg-1 and 103,06 μg kg-1. The highest BPA mass fractions were found in areas under anthropogenic impacts: in Kaštela Bay, Split city harbour, Bakar Bay and Krka River estuary. Monthly analysis of BPA distribution indicated no seasonal oscilations of BPA mass fractions in sediments and suspended matter. Comparison of results of BPA analysis during a longer period indicated an increase in BPA mass fractions in sediments at the majority of sampling sites. The research revealed the lack of a direct link between the fine grain fractions in the sediment and the mass fractions of BPA, as has been assumed in the hypothesis of the dissertation following the usual relationship between the proportion of organic matter, organic carbon, phosphorus and fractions of silt or clay. The reason is probably completely different origin of BPA and its chemistry in the sediment that is significantly different from the cycle of biogenic elements in the marine ecosystem.
