“…The sedimentation leads to an accumulation of contaminants in the pond sediments. However, contaminants trapped in sediments can under certain physicochemical conditions be released and contaminate overlaying and surrounding waters (Salomons et al 1987). Ponds are very important for biological diversity (Williams et al 2004).…”

Sediments from 18 different road runoff detention systems, located on the Swedish West Coast, were assessed for their ecological hazard potential. Thirteen of the sites were detention ponds, three were manholes within the same sedimentation construction, and two were detention basins handling wash water from road tunnels. Sediments from all sites were analysed for a range of physico-chemical parameters and contaminants, and screened for acute toxicity using Hyalella azteca (sediment), Daphnia magna (elutriate), and Ceriodaphnia dubia (elutriate) as the test organisms, and for chronic toxicity using C. dubia as the test organism. The benthic fauna of the thirteen detention ponds was also studied. Sediment quality guidelines probable effect levels were exceeded for one or several contaminants at half of the sites, and one third revealed toxicity in some of the bioassays. Most of the detention ponds were dominated by tolerant taxa indicating low biological quality. Relationships between contaminant concentrations, toxicity in bioassays, and benthic fauna were, however, found to be weak. Extractable organic Zn, which was used as a tire wear marker, correlated with Zn, Cu, presumably from brake linings, and W, a common component of tire studs. The highest concentration, which was found in the manholes (14 mg kg −1 ds), corresponds to a tire wear concentration of 11 g kg −1 ds. The results of the present study have shown that traffic related contaminants accumulate in the studied runoff treatment systems, and, therefore, the maintenance of them is crucial in order to prevent contamination of surrounding waters.

“…Also, increased oxygen in deeper portions of the sediment may promote the formation of metal hydroxides and metal precipitates (F6rstner 1984) which are more mobile or are readily converted to cation form, but which are still associated with the solid phase of the sediment. Any of these changes to solid phases of cadmium would be orders of magnitude less than the overall sediment concentration ~g1-1 versus /~gg-a) (see Swartz et al 1985, Salomons et al 1987) and would not create detectable differences in sediment analyses but could be biologically significant.…”

Sublethal effects of cadmium on arm regeneration in the burrowing brittlestar, Microphiopholis gracillima

1996

: To assess the sublethal effects of sediment-bound cadmium on arm regeneration of Microphiopholis gracillima, a burrowing brittlestar, experiments were conducted to quantify the tissue and morphology of regenerating arms, the uptake of cadmium in various tissues and the effect M. gracillima had on the cadmium pools in muddy sediments. Regenerated arms of cadmium-exposed M. gracillima are thinner, with proportionally less soft and skeletal tissue and a greater number of developing ossicles than animals held in sediment without cadmium. Microphiopholis gracillima decreased pore water cadmium concentrations in muddy sediments. Uptake of cadmium in tissues dominated by the calcium carbonate endoskeleton was proportional to the measured sediment cadmium concentration, while concentrations in whole regenerating arms were more closely related to the pore water concentration. Both calcium and cadmium are accumulated in the early stages of arm regeneration with an apparent interaction which interferes with ossicle construction. Sediment-bound cadmium has a negative effect on the organism's recovery from sublethal tissue loss and, ultimately, its long-term survival.

“…Due to oxidative processes that occur during suspension of anoxic sediment layers, redox potential and pH value can increase and decrease, respectively. These changes can be of toxicological relevance because the variation of redox and pH values has been shown to influence the release or bioavailability of former sedimentbound toxic substances (Koelling 1986;Salomons et al 1987;Calmano et al 1992Calmano et al , 1993Stumm 1992;Zoumis et al 2001;Cantwell et al 2002), e.g. a decrease of the pH value increases the freely dissolved heavy metal concentration.…”
