The load of various hydrophobic organic compounds (HOCs) on the Baltic Sea aquatic environment is considerable. This investigation samples the water area around Stockholm, of special concern since it is one of the most densely populated urban areas in the Baltic region. Stockholm also houses several power plants, municipal waste incinerators, waste water treatment plants, ports and oil terminals. The runoff from a large lake also passes through the estuarine-like archipelago of Stockholm. Due to the high particulate-water partition coefficients (K[sub p]) of most ecotoxicologically relevant HOCs, particulate matter (PM) becomes very important for occurrence and distribution in the aquatic environment. This PM is the basic food source for important organisms in the benthic, pelagic and littoral parts of the aquatic ecosystem. The load of various HOCs such as petrogenic hydrocarbons (PHCs), various polynuclear aromatic compounds (PACs), and chlorinated hydrocarbons such as polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in association with PM in the aquatic environment of the Stockholm area is well documented. However, the ecotoxicological relevance of organic extracts of PM, including the above identified compounds and various unidentified HOCs, is not fully evaluated. To evaluate the genotoxic potential of extracts of PM, collected with sediment traps in the Stockholm water area and in the open northern Baltic, we used the Ames test on Salmonella typhimurium strain TA100, with and without a metabolizing system. After extraction and before the mutagenicity tests all PM samples were fractionated on an HPLC-system into three fractions containing aliphatic/monoaromatic-, diaromatic, (containing, e.g., PCDD/Fs and PCBs) and polyaromatic compounds (containing various PACs). The relative mutagenic potential of these fractions at the different sediment trap sampling stations are discussed and evaluated. 13 refs., 1 tab.
