“…They are byproducts of the paper, wood, and herbicide industries and are formed in the incineration of some chlorinated organic compounds (280 (282). Although 31% of total PCBs manufactured are currently estimated to be present in the global environment, only 4% of cumulative world production can be accounted for as degraded or incinerated.…”

“…Much interest has been devoted to the interactions among benthic fauna, sediment and pore water for toxic organic chemicals, particularly for poly-chlorinated biphenyls (PCBs), whose ecotoxicological significance has been recognized (Jensen et al, 1969;Peakall & Lincer, 1970). Based on field and laboratory tests, the following factors have been shown to affect the bioaccumulation of PCBs in benthic organisms (Allan, 1984): -toxic chemical structure (Goerke & Ernst, 1977;Langston, 1978;Duinker & Hillebrand, 1983;Shaw & Connell, 1984); -organism size (McCrea, 1982); -duration of exposure (Tatem, 1982); -chemical concentration in the sediment (Fowler et al, 1978;Elder et al, 1979;Stainken & Rollwagen, 1979); and -sediment characteristics, especially organic content and particle size (Engler, 1979;Tofflemire et al, 1979;Lynch & Johnson, 1982).…”

The review article covers three major aspects of scientific research on sediment-associated contaminants during the last 20 years: (i) identification and monitoring of sources and distribution (sampling; sample preparation; analyses, mainly of non-residual fractions; estimation of pollution potential); (ii) study of processes and mechanisms of pollutant transfer (interactions between dissolved and particulate element species; particle environments; transport and diagenesis: colloids; surface microlayers; particle related processes; bioturbation; dredging operations; remobilization of toxic elements; bioaccumulation of organic chemicals: solid/dissolved distribution of contaminants); (iii) assessment of the environmental impact of particle-bound pollutations (chemical extraction sequence; sediment bioassay; combined chemical/biological test procedures). Enstead, empirical tests developed from multi-disciplinary research on biological, chemical and physical factors are applied for assessing the reactivity, mobility and bioavailability of sediment-bound pollutations and for estimating the validity of remedial measures.
