“…Detailed information for the BCR procedure is provided in Table S1 . With respect to the BCR method, the exchangeable fraction was considered as the bioavailable fraction (Bielicka-Giełdo n et al, 2013; Rosado et al, 2016). Concentrations of Cu and Zn were determined by atomic absorption spectrometry (PinAAcle 900, Perkin Elmer; detection limit, Cu ¼ 0.01, Zn ¼ 0.01 mg L À1 ) and Pb, Cd, and Cr were quantified by inductively coupled plasma mass spectrometry (Agilent 8800 ICP-MS, Agilent Technologies; detection limit, Pb ¼ 0.005,…”

“…Sediment characteristics (e.g., organic matter, redox status and pH) have a strong effect on distribution of metal fractions and their bioavailability, such as the positive correlation observed between organic matter and the oxidizable fraction of Cu and Pb in Tasik Chini, Malaysia (Ebrahimpour and Mushrifah, 2008). Thus, multistep sequential extraction schemes have been used to estimate the bioavailability of metals in sediments and their potential risk to aquatic ecosystems and humans (Sakan et al, 2016).…”

TitleDistribution and source analysis of heavy metal pollutants in sediments of a rapid developing urban river system. Heavy metal pollution of aquatic environments in rapidly developing industrial regions is of considerable global concern due to its potential to cause serious harm to aquatic ecosystems and human health. This study assessed heavy metal contamination of sediments in a highly industrialized urban watershed of eastern China containing several historically unregulated manufacturing enterprises. Total concentrations and solid-phase fractionation of Cu, Zn, Pb, Cr and Cd were investigated for 39 river sediments using multivariate statistical analysis and geographically weighted regression (GWR) methods to quantitatively examine the relationship between land use and heavy metal pollution at the watershed scale. Results showed distinct spatial patterns of heavy metal contamination within the watershed, such as higher concentrations of Zn, Pb and Cd in the southwest and higher Cu concentration in the east, indicating links to specific pollution sources within the watershed. Correlation and PCA analyses revealed that Zn, Pb and Cd were dominantly contributed by anthropogenic activities; Cu originated from both industrial and agricultural sources; and Cr has been altered by recent pollution control strategies. The GWR model indicated that several heavy metal fractions were strongly correlated with industrial land proportion and this correlation varied with the level of industrialization as demonstrated by variations in Chemosphere 207 (2018) 218e228 local GWR R 2 values. This study provides important information for assessing heavy metal contaminated areas, identifying heavy metal pollutant sources, and developing regional-scale remediation strategies.

“…Total contents of heavy metals were detected using national standards [28,29]. Studied metals fractions using a sequential extraction scheme and procedure proposed by Tessier et al was used to partition the toxic metals, which was widely applied in various studies of heavy metal [30][31][32] [33]. Metal concentrations were determined using a PerkinElmer NexION300X inductively coupled plasma mass spectrometer (ICP-MS) and reported on a dry weight basis (mg•kg -1 ).…”

The potential ecological risks of cobalt (Co) and (Sb) in the sediments of the black-necked crane habitats in Caohai Lake, Guizhou Province were assessed based on total concentration and speciation via Tessier sequential extraction procedure. The results showed that the concentration of Co in the study region is in the range of 4.29-23.79 mg•kg-1 , with an average of 15.41±3.4 mg•kg-1 , which is lower than the soil background concentration in Guizhou Province. The concentration of Sb is in the range of 1.4-1.69 mg•kg-1 , with an average of 1.51±0.3 mg•kg-1 , which is 13.7 times higher than the soil background value of Sb in Guizhou Province. The concentrations of Sb in the west and southeast regions were greater than those in the other parts of the habitats. Co mainly existed in residual and Fe-Mn oxides forms, which account for 68.73-89.14% of total Co. However, Sb mainly existed in residual forms, which account for 79.84-93.11% of the total Sb. The carbonate and organic forms of the two elements and the Fe-Mn oxides of Sb decreased along with decreased water depth. The exchangeable fractions of the two elements were lower than 1% and do not exhibit obvious changes with water depth. The potential ecological risk index of Co (E Co) shows that Co in the five habitats (Liujiaxiang, Zhujiawan, Wangjiayuanzi, Huyelin, and Yangguanshan) was at a moderate risk level. The potential ecological risk index of Sb (E Sb) shows that Sb in the five habitats was at a considerable risk level. All of the RI indexes were at mild and moderate risk levels, which Sb makes a large contributor. According to an assessment of the ratio of the secondary phase to the primary phase, Co and Sb present little pollution and potential ecological risk in the study regions. It can be seen that the evaluation of the ecological impact by the total

Sequential extractions, in particular, are simple low cost methods, that can be applied to different soil types (Rosado et al, 2016), and can help understanding HMs and metalloids leachability, solubility, and mobility (Kaakinen et al, 2015), providing the most information about the fate, transport, and behaviour of HMs in soil. However, most studies focus on (1) assessing effects and toxicity of one contaminant in isolation (Cui et al, 2005),…”

Mobility of heavy metals at contaminated sites is mainly influenced by the soil physicochemical properties and environmental conditions, therefore assessing heavy metals (HMs) and metalloids fractionation can provide insights into their potential risk and the mechanisms that regulate bioavailability. A 12-months mesocosms experiment was setup to investigate the effect of physicochemical factors (pH, moisture, and temperature) and weathering (time) on HMs and metalloids fractionation in three different multi-contaminated soil matrices (low, medium, and high contamination) collected from a soil treatment facility located in the United Kingdom, and two rural contaminated soil samples. The study demonstrates that even though Pb and Zn were found associated with the exchangeable fraction in the soil with the highest contamination (total average Pb 3400 mg/kg, and total average Zn 2100 mg/kg in Soil C), neither the condition applied nor the weathering caused an increase in their mobility. Although it was expected that lower pH (4.5) would favours the dissociation of HMs and metalloids, no significant differences were observed, potentially due to the initial alkaline pH of the genuine-contaminated soil samples. The results show that even though total concentration of Pb, Cu, and Zn exceed the soil standards and guideline values, HMs were predominantly associated with the non-exchangeable fraction, while only 5% were dissolved in the pore water fraction (potentially bioavailable). In addition, the mobility and bioavailability of HMs remained constant over the 12 months monitoring, suggesting that these soils pose negligible risk to the environment.
