“…The AVS model that included the f OC in the normalization procedure also was highly predictive. Burton et al predicting metals toxicity also was shown in marine systems by Hansen et al [6] and supported by others [1,[2][3][4][7][8][9][10][11][12][13][14][15]. Organic carbon is a potentially important partitioning phase for metals in sediment and in water.…”

A fields study was conducted to validateconcentrations of zinc in feshwater sediments that are tolerated by benthic macroinvertebrate communities and to determine whether a relationship exists with the acid volatile sulfide (AVS)–simultaneously extracted metal (SEM) model. In both the lake and riverine systems, one sediment type was high in AVS and one low in AVS, which resulted in zinc‐spiked sediments that ranged from low to high SEM to AVS ratios. The colonization trays were sampled seasonally, ranging from 6 to 37 weeks of exposure, and were evaluated using several appropriate benthic indices. Results of the field evaluations at the four test sites confirmed the validity of the AVS‐SEM model, predicting benthic macroinvertebrate effects correctly 92% of the time. In sediments where the SEM to AVS ratio or the AVS and organic (OC)–normalized fractions exceeded 8 and 583 μmol/g of OC, toxicity was observed from the zinc‐spiked sediments. Conversely, when the SEM to AVS ratio or OC‐normalized AVS fractions were less than 2 or 100 μmol/g of OC, no toxicity was observed. In the range of 148 to 154 μmol/g of OC, toxicity varied in two treatments. Total zinc concentrations in sediments showed no relationship to benthic effects. The most impaired benthic community occurred in the high‐gradient stream sediments, which had low OC and AVS concentrations and SEM to AVS ratios of 33 and 44 in the spiked sediments. Five to six benthic metrics were depressed at SEM to AVS ratios of 8.32 and 9.73. The no‐observed‐effect level appeared to be near a SEM to AVS ratio of 2, with slight to no effects between ratios of 2.34 and 2.94. No sites with ratios of less than 2 showed any adverse effects.

“…For several cationic metals, a number of studies have shown conclusively that, when acid‐volatile sulphide concentrations exceed those of metal simultaneously extracted, metal concentrations in the interstitial water are low and toxicity is not observed (e.g. Berry et al . 1996).…”

The impact of a sewage treatment plant's effluent on sediment quality in a small bay in Lake Geneva (Switzerland–France). Part 1: Spatial distribution of contaminants and the potential for biological impacts

The purpose of this study was to assess the quality of bottom sediment collected in the Bay of Vidy (Lake Geneva, Switzerland) which receives sewage treatment plant discharges from the city of Lausanne and its surroundings. Thirty-eight sediment samples were taken, forming a dense network. Samples of that portion of the sediment that has accumulated since phosphorus removal (via iron precipitation) was instituted at the plant in 1971 were analysed for heavy metals, nutrients and organic micropollutants and subjected to Microtox toxicity evaluation (organic extract). The distribution patterns of contaminants, as well as principal components analysis, demonstrated that the sewage treatment plant's effluent is the main source of local sediment contamination. This was not supported by the Microtox results. In close proximity to the outlet pipe of the sewage treatment plant, contaminants showed very high median concentrations for virtually all the parameters measured, at levels above those believed to elicit biological responses. A major environmental impact is clearly occurring in this coastal region of the lake and remediation of this situation is believed to be important in order to protect the Lake Geneva ecosystem

“…In the absence of compelling field data, one of the best ways to gain insight into the toxicity and bioavailability of a metal in sediment is to perform spiked‐sediment toxicity tests [3]. Relatively few studies have been performed with freshwater sediments spiked with silver, and none have been performed with marine sediments.…”

Abstract-Previous experiments conducted with freshwater sediments spiked with silver have shown that, when expressed on a dry weight basis, the toxicity of silver is sediment-specific and dependent on the form of silver added (e.g., AgNO 3 , Ag 2 S). This study was conducted to assess the usefulness of silver interstitial water toxic units (IWTU) and acid volatile sulfide (AVS) concentrations in predicting the biological effects of silver species across sediments, regardless of the species of silver present. Two saltwater sediments were spiked with a series of concentrations of silver. The amphipod, Ampelisca abdita, was then exposed to the sediments in ten-day toxicity tests. Amphipod mortality was sediment-specific when expressed on a dry weight basis, but not when based on IWTU or simultaneously extracted metal (SEM)-AVS. Sediments with an excess of AVS relative to SEM had IWTU Ͻ0.5, and were generally not toxic. Sediments with an excess of SEM relative to AVS had silver IWTU Ͼ0.5, but no measurable AVS, and were generally toxic. Sediments with measurable AVS were not toxic. Reanalysis of the previously published data from the freshwater sediments spiked with silver showed mortality to be correlated with nominal SEM-AVS and with silver IWTU. Taken together, these results support the use of AVS and silver IWTUs in predicting the toxicity of silver in sediments.
