“…Sediment environmental conditions (e.g., dissolved O 2 , conductivity, E h ) for each sampling location can be found in Luo et al (2008), save for the Xinjiang river site, which can be characterized as a fast-moving, sandy tributary. Prior to this study, researchers had shown the presence of toxic heavy metals (Cd, Cu, Ni, Pb, and Zn) associated with Poyang Lake's sediment due to anthropogenic activity in the watershed basin (Chen et al 1989;Luo et al 2008;Yuan et al 2011).…”

Heavy metal concentrations within freshwater systems can increase as a result of anthropogenic inputs, which in turn can influence microbial community composition and community function. In this study, lake sediments collected from two historically heavy metal impacted geographical regions [Poyang Lake, People's Republic of China (PRC), and sites adjacent to the Muskegon Watershed, MI (USA)] were analyzed for total and available heavy metals (Cd, Cr, Cu, Pb, and Zn), as well as microbial community structure using highthroughput sequencing technology. In PRC tributaries leading into Poyang Lake, Zn was found to be the most available metal species. In USA sites, available Cd was higher in Mona Lake sites than alternate USA sites. In both regions, results indicate a weak influence of metals on microbial alpha and beta diversity, but strong positive and negative correlations of available heavy metals with specific taxonomic groups of bacteria and archaea. Further, individual metal species impacted microbial groups and operational taxonomic units differently, suggesting that individual metal species are important in determining which microbial groups and species prevail under heavy metal stress, particularly in the case of bioavailable metals. In PRC, several taxonomic groups were correlated positively with Zn, including Actinobacteria, Bacteroidetes, Proteobacteria, and Verrucomicrobia. Geobacter and Pedosphaerales were both correlated positively to Cr in the same sites, while other correlations with microbial groups were negative. In sites from the USA, Deltaproteobacteria were correlated positively with Cd, while Betaproteobacteria were negatively correlated, suggesting that Cd resistance may differ at the level of Class within Proteobacteria. This study highlights the importance of analyzing available metals when examining the impact of this disturbance on microbial community structure within aquatic sediments.

“…Of the four heavy metals analysed, zinc and lead were present in relatively greater amounts. For copper, the lower levels were possibly a reflection of the importance of organic matter in accumulating copper (Chen et al 1989; Pardo et al 1990; Chen et al 1996). Cadmium was detected very rarely at all three sites.…”

Sediments of three streams draining sandstone catchments in Sydney, Australia, were sampled under low flow conditions over a 2-year period. Two streams receive urban contaminants, one (the reference creek) has an undeveloped catchment. Levels of sediment copper, zinc, cadmium and lead (total and speciated) and phosphorus (total and organic) were determined, as well as total organic carbon, particle size fractionation and cation exchange capacity. A range of quality parameters were also measured for interstitial waters. Sediments were characterized by very low organic matter (< 2% by weight) and low cation exchange capacity (< 3 mmol Na 100 g Ϫ1 ), due to high contents of coarse and fine sands (> 95%). Despite a low accumulation of heavy metals and phosphorus in the long term, the sediments were nevertheless a sink for these constituents. Greatest proportions of sediment zinc and lead were associated with hydrous metal oxide coatings, or coarse waste particles. Apart from a substantial residual component, copper was preferentially associated with organic matter. Cadmium was rarely detected in any stream. Multidimensional scaling showed that under low flow conditions the three sites had distinct sediment chemistries. However, high levels of temporal and spatial variability were apparent within the urbanized sites, consistent with those streams regularly receiving discharges of diverse composition. Poor sediment and interstitial water qualities were often observed in the two urban sites, although such conditions did not occur continuously. Poor interstitial water quality was also seen on occasion in the reference stream; however, poor sediment quality was never detected at this site. Considering surficial sediments of Hawkesbury Sandstone streams may be suspended during high flow conditions, it was concluded that surface waters were a more reliable indicator of stream condition for short-term monitoring studies.

“…Internationally, there is some controversy over which fractions represent a hazard to the environment, although a number of workers (e.g. Gibbs, 1977;Chen et al, 1989;Stone and Droppo, 1996) have suggested that the first four fractions removed by the Tessier et al (1979) method represent potentially 'available' fractions. Conversely, metals in the residual fraction will only be released by long-term weathering of the sediment.…”

Abstract:In recent years, there has been an increasing awareness of the important role of fine sediment in the transport and storage of metals in fluvial systems. However, there has been little research on the behaviour of contaminated sediment in industrial rivers in the UK. This paper examines spatial and temporal variations in the concentration and speciation of lead, copper and chromium associated with suspended sediment in the River Aire in Yorkshire, UK. An increase in the total concentration of all three metals in sediment was identified in the lower reaches, which reflected inputs of road dust, sewage and industrial effluents. Spatial variations in the chemical speciation of the metals were also identified. The iron-manganese oxides and organic fractions were the most significant for the adsorption of metals by sediment. Both the concentrations and speciation of sediment-associated metals exhibited substantial temporal variation. Such variation reflected the accumulation of metals and organic matter on the river-bed during low flows, the subsequent remobilization of the sediment at high flows and the additional supply of sediment from uncontaminated and contaminated sources, including pulse inputs of road dust, sewage and industrial effluent. The findings presented have important implications for the development of effective catchment management strategies for the control of pointand diffuse-source pollution.
