“…Urban stormwater and drainage systems provide pathways for contaminants to enter receiving waters, including metals bound to soils and consequently sediments of urban waterways frequently exhibit elevated metal concentrations (Ruiz 2001;Liu et al 2006;Ip et al 2007). A strong increase in heavy metal concentrations towards stormwater canal discharge points and high dissolved and particulate phase metal concentrations in fluvial systems (Barry et al 1999;Davis and Birch, in press) suggest landderived metals make an important contribution to contamination of Sydney estuary.…”

Total topsoil 50th percentile Cu, Pb and Zn concentrations (n=491) in the Sydney estuary catchment were 23 μgg −1 , 60 μgg −1 and 108 μgg −1 , respectively. Nine percent, 6% and 25% of samples were above soil quality guidelines, respectively and mean enrichment was 14, 35 and 29 times above background, respectively. Soils in the south-eastern region of the catchment exhibited highest metal concentrations. The close relationship between soil metal and road network distributions and outcomes of vehicular emissions modelling, strongly suggested vehicular traffic was the primary source of metals to catchment soils. Catchment soil and road dust probably make an important contribution to contamination of the adjacent estuary. The concentration of soil metals followed the land use trend: industrial> urban>undeveloped areas. A high proportion (mean 45%, 62% and 42%, for Cu, Pb and Zn, respectively) of metals in the soils may be bioavailable.

“…Soils can be fractionated into a series of particle size ranges with various chemical and physical properties that play different roles in metal bioavailability. Fine particles have high specific surface areas, producing much more net negative charges on the soil surfaces and larger amounts of silicates, organic matter, and hydroxides of Fe/Al/Mn/Si than coarse particles (Liu et al 2006). These different properties will result in different metal adsorption and immobilization capacities when metals enter the soil (Minkina et al 2011) and will also confer different desorption abilities (Gray et al 1999).…”

Aims Phytoextration of metal polluted soils using hyperaccumulators is a promising technology but requires long term successive cropping. This study investigated the dynamics of plant metal uptake and changes in soil metals over a long remediation time. Methods A soil slightly polluted with metals (S1) was mixed with highly polluted soil (S4) to give two intermediate pollution levels (S2, S3). The four resulting soils were repeatedly phyto-extracted using nine successive crops of Cd/Zn-hyperaccumulator Sedum plumbizincicola over a period of 4 years.Results Shoot Cd concentration decreased with harvest time in all soils but shoot Zn declined in S1 only. Similar shoot Zn concentrations were found in S2, S3 and S4 although these soils differed markedly in metal availability, and their available metals decreased during phytoextraction. A possible explanation is that plant active acquisition ability served to maintain plant metal uptake. Plant uptake resulted in the largest decrease in the acid-soluble metal fraction followed by reducible metals. Oxidisable and residual fractions were less available to plants. The coarse soil particle fractions made the major contribution to metal decline overall than the fine fractions. Conclusion Sedum plumbizincicola maintained long term metal uptake and the coarse soil particles played the most important role in phytoextraction.

“…Research done by Liu et al (2006) has shown that heavy metals' concentrations are 2-4 times greater in fine deposits than in the sediments enriched with coarser grain-size fractions. Similar results were achieved in case of Pb, Zn, Cu, Ni, and Cr concentrations in the deposits of the Mekhna river, Bangladesh (Hawa Bibi et al 2006), where contents of these elements were much higher in silts than in sands.…”

Research concerning chemical constitution of alluvial sediments was done in the lower course of the Obra river (Western Poland). The fragment of vertical profile, which consisted of various alluvial sediments (fine sands, peats, and sandy silts) was chosen for detailed analysis. The main research problem was to determine if lithology and chemical constitution of alluvial deposits are interconnected in a distinct way within studied section of the Obra river valley, and, if changes of chemical elements' concentration could be used to illustrate depositional processes, which take place in riverbed and floodplain. Concentrations of Fe, Mn, Cu, Zn, Ca, Mg, and K were determined in collected sediment samples. Next, geochemical groups of alluvial sediments were distinguished using cluster analysis. Investigated changes of chemical elements' concentration show that there is a distinct border between the environment of organic sediments, which marks the place of former functioning of the Obra riverbed, and sandy silts, which were deposited within floodplain during floods. Besides, floodplain sediments, riverbed sediments, and reductive environment within peat deposits were singled out on the basis of the analysis.
