“…The speciation results corroborated the high As levels in sediments previously recorded from intertidal mudflats of Sundarban (Chatterjee et al, 2009b), mainly derived from untreated or semi-treated municipal and industrial discharges from multifarious industries located upstream of the Hugli (Ganges) River (Fig. 1) as endorsed by previous workers (Luoma and Cloern, 1982;Moore and Ramamoorthy, 1984).…”

“…A strong association of Fe and Mn in Sundarban sediments was previously recorded by Chatterjee et al (2009b) and the precipitated Fe in the form of oxyhydroxides has the affinity to scavenge other metals including As as they pass through the water to the sediments (Waldichuk, 1985). Only limited information is available on arsenic compounds in marine sediments, the major compounds in the pore water of marine sediments are usually As III and As V , although methylated arsenicals (Reimer & Thompson, 1988) and arsenoribosides (Ellwood and Maher, 2003) have also been reported as minor constituents in sediments.…”

Arsenic concentrations reported by Chatterjee et al (2009b) were 3 to 18 mg kg -1 , exceeding the ERL of 8 mg kg -1 . Therefore, the speciation of arsenic in sediments is of great significance because it may provide information about the cycling of arsenic in the wetland ecosystem.…”

Abstract:This paper documents the concentration of total arsenic and individual arsenic species in four soft-bottom benthic polychaetes (Perenereis cultifera, Ganganereis sootai, Lumbrinereis notocirrata and Dendronereis arborifera) along with host sediments from Sundarban mangrove wetland, India. An additional six sites were considered exclusively for surface sediments for this purpose. Polychaetes were collected along with the host sediments and measured for their total arsenic using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Arsenic concentrations in polychaete body tissues varied greatly, suggesting speciesspecific characteristics and inherent peculiarities in arsenic metabolism. Arsenic was generally present in polychaetes as arsenate (As V ranges from 0.16 -0.50 mg kg -1 ) or arsenite (As III ranges from 0.10 -0.41 mg kg -1 ) (30 to 53% as inorganic As) and dimethylarsinic acid (DMA V ; <1 to 25%). Arsenobetaine (AB; <16%), and PO 4 -arsenoriboside (8 to 48%) were also detected as minor constituents, whilst monomethylarsonic acid (MA V ) was not detected in any of the polychaetes. The highest total As (14.7 mg kg -1 dry wt) was observed in the polychaete D. arborifera collected from the vicinity of a sewage outfall in which the majority of As was present as an uncharacterized compound (10.3 mg kg -1 dry wt) eluted prior to AB. Host sediments ranged from 2.5 to 10.4 mg kg -1 total As. This work supports the importance of speciation analysis of As, because of the ubiquitous occurrence of this metalloid in the environment, and its variable toxicity depending on chemical form. It is also the first work to report the composition of As species in polychaetes from the Indian Sundarban wetlands.

“…4). In these cases, metal concentrations higher than background levels indicated mild starting levels of pollution due to the use of fertilizers in agricultural fields [36,37]. Moreover, we could observe complex pollution of multi-heavy metals in reclaimed field (Sites 5-6) and adjacent wetlands (Sites 2-4).…”

Surface soils were collected in the aquatic-terrestrial ecotone (ATE) of Yongnianwa wetland, downstream of Haihe River basin of North China in June of 2007. Samples were subjected to a total digestion technique before they were analyzed for total concentrations of Cr, Cu, Ni, Pb, and Zn to investigate their pollution levels in the ATE. The contamination index, integrated contamination index, geoaccumulation index, toxic units, and sum of toxic units were adopted to assess the heavy metal contamination levels and ecotoxicity, respectively. The results showed all the selected element concentrations in upland soils of the ecotone were relatively higher than those in the lowland soils. No Cr pollution was observed in all soil samples, but almost all samples were slightly polluted by Cu, Ni, Pb, and Zn except for Site 1. The contamination indexes and geoaccumulation indexes consistently presented no contamination for Site 1 and slight contamination for other sites. The STUs increased from lowland to upland, but the whole level of toxicity in this ecotone was relatively low. IntroductionAquatic-terrestrial ecotone (ATE) is an important functional interface zone between the aquatic and terrestrial ecosystems, owing to the protection to water body from harmful impacts of land use practices on the terrestrial ecosystem [1,2]. The soils in these ATEs have been widely researched due to their functions and capacities of retaining nutrients, i.e., carbon, nitrogen, and phosphorous [3][4][5][6]. However, few studies have focused on the ecological functions of ATE in reducing pollution risks of heavy metals from the reclaimed upper wetland to adjacent aquatic ecosystems, especially in a typical water-shortage inland plain [7].Yongnianwa is the third largest lacustrine wetland located in the North China Plain. Large number of lakeshore wetlands has been cultivated in the past decades, which led to some heavy metal (e.g., Cu and Ni) contamination of water body in the lake due to extensive agriculture activities [8]. However, little information is available on spatial variations of soil heavy metal concentrations and contamination levels along the distances far from the farmland and the effect of aquatic-terrestrial buffer zone in water-quality protection and lake management. There appears to be a direct conflict between need for large buffer widths to reduce perimeter/area of buffers for ecologic purposes and the need for small widths to reduce perimeter/ unit area of non-buffer area for economic and agricultural purposes [9][10][11]. Thus, the utility and efficiency of vegetated buffer strips with a certain width need to be detected and studied in order to protect water quality of rivers or lakes. Most researchers have widely used the contamination indexes, integrated contamination index, and geoaccumulation index, etc. to assess heavy metal contamination [12][13][14][15][16]. The primary objectives of this study were (1) to study spatial variations of heavy metal concentrations in wetland soils along the ATE of Yongnianwa wetl...

“…Many previous studies have reported that heavy metal contamination has occurred in river basins or estuaries due to the cause-effect relationship between human effects and the soil quality (Xiao et al 2011;Karim et al 2013). Therefore, it is necessary to investigate distributions and the extent of heavy metal pollution in coastal wetlands and to provide scientific suggestions for coastal management (Chatterjee et al 2009;Liu et al 2014).…”

Coastal and estuarine areas are often polluted by heavy metals that result from industrial production and agricultural activities. In this study, we investigated the concentration trait and vertical pattern of trace elements, such as As, Cd, Ni, Zn, Pb, Cu, and Cr, and the relationship between those trace elements and the soil properties in coastal wetlands using 28 profiles that were surveyed across the Diaokouhe Nature Reserve (DKHNR). The goal of this study is to investigate profile distribution characteristics of heavy metals in different wetland types and their variations with the soil depth to assess heavy metal pollution using pollution indices and to identify the pollution sources using multivariate analysis and sediment quality guidelines. Principal component analysis, cluster analysis, and pollution level indices were applied to evaluate the contamination conditions due to wetland degradation. The findings indicated that the concentration of trace elements decreased with the soil depth, while Cd increases with soil depth. The As concentrations in reed swamps and Suaeda heteroptera surface layers were slightly higher than those in other land use types. All six heavy metals, i.e., Ni, Cu, As, Zn, Cr, and Pb, were strongly associated with PC1 (positive loading) and could reflect the contribution of natural geological sources of metals into the coastal sediments. PC2 is highly associated with Cd and could represent anthropogenic sources of metal pollution. Most of the heavy metals exhibited significant positive correlations with total concentrations; however, no significant correlations were observed between them and the soil salt and soil organic carbon. Soil organic carbon exhibited a positive linear relationship with Cu, Pb, and Zn in the first soil layer (0-20 cm); As, Cr, Cu, Ni, Pb, and Zn in the second layer (20-40 cm); and As, Cr, Cu, Ni, Pb, and Zn in the third layer (40-60 cm). Soil organic carbon exhibited only a negative correlation with Cd (P<0.05), in the second and third layers. As, Cr, Cu, Ni, Pb, and Zn exhibited lower geoaccumulation index values (I geo values), which averaged less than 0 in the three soil layers, this finding indicates that the soils have remained unpolluted by these heavy metals. The mean concentrations of these trace elements were lower than Class I criteria. The degradation wetland restoration suggestions have also been provided in such a way as to restore the reserved flow path of the Yellow River. The results that are associated with trace element contamination would be helpful in providing scientific directions to restore wetlands across the world.
