Phthalates in Swedish sediments

Technical Report:

Abstract

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  More>>
