“…Although phosphates and phthalates are well known technical constituents released in major amounts into the aquatic environment (e.g. Huhn 1978, Bohlen et al 1990), the diversity of individual compounds as described in this study has been reported rarely. On the other hand further more specific technical additives were detected including TMDD used as dispersing additives in pigment paints, the organic solvent NMP, triacetine used as plasticizer with fungistatic activities, and an isomeric mixture of di-iso-propylnaphthalenes (DIPNs) which are utilized as constituents of coating agents, adhesives, PCB substitutes, as well as heat transfer and insulating oils.…”
