| Abstract | With Swedish summary.. The objectives of the study were to produce reliable 'background' data of phthalate concentrations in sediments, and to assess the relative importance of phthalate input from both diffuse sources and from point-sources. Much effort was first concentrated on adopting new laboratory and sampling practices with a minimum of contamination risks. Thereafter, surface sediments (0-2 cm) from different types of environments were sampled and analysed for the following nine substances and mixtures: DMP, DEP, DEHP, DBP, BBP, DnOP, DnNP, DINP and DIDP. The sampling stations were selected in order to represent: * 'background' concentrations from different parts of Sweden (remote lakes), * a gradient of increasing anthropogenic influence, downstream of a river system and * water-bodies acting as recipients of 'points-sources' (plastic industries). One sediment core was also analysed for depth profiles of phthalates. DEHP varied between 0.01 and 0.4 (mu)g/g dw in the remote lakes. The concentrations of DBP and BBP were 0-0.9 (mu)g/g dw while the other phthalates were mostly undetectable. In the gradient with increasing anthropogenic influence, DEHP concentrations (normalised to organic content in the sediments), increased downstream. The DEHP-concentrations at the two points sources were 33 and 47 (mu)g/g dw respectively, which represent more than a ten-fold decrease compared to concentrations measured in 1983. Comparatively high concentrations of the phthalate mixture DINP was measured in the sediments at one of the points sources. 17 refs, 7 figs, 4 tabs |
