“…Several studies have been conducted on heavy metal contamination throughout the world, including Iran (e.g., Baptista Neto et al, 2001;Secrierus and Secrierus, 2002;Moreno et al, 2009;Yap and Pang, 2011;Bastami et al, 2012Bastami et al, , 2014Bramha et al, 2014;Wang et al, 2015). The concentrations of the heavy metals studied in this study were markedly higher than those of other regions, in most cases.…”

“…Thus, these three elements should be selected as priority indicators and paid special attention (Chen et al 2015). It has been reported that Cu, Cr, and Zn may originate from anthropogenic sources such as the development of aquaculture and fossil oil (Grosbois et al 2009;Wang et al 2015b). In our study, the extra metal input from traffic pollution when plants are harvested every winter and from the feedstuffs in the fish ponds nearby might be responsible for the significantly higher concentration of Cu, Cr, and Zn in the reclamation area.…”

Owing to accelerating reclamation activities in the coastal wetland reserves, it is of great importance to analyze the effects of wetland reclamation on heavy metal pollution in these areas. Soil samples were collected from reclamation and natural habitats in Yancheng National Nature Reserve for Coastal Rare Birds in Jiangsu, China to investigate the effects of reclamation on the total amounts, availability, and vertical distribution of seven elemental heavy-metal pollutants. In general, the total amount and availability each element were relatively low in the two habitats and were classified as Bno pollution^. Reclamation was found to significantly increase the total amount of As, Cu, and Zn as well as the pollution degrees of As, Cr, and Zn. The availability of Cu, Pb, Cd, and Cr can also be significantly affected by reclamation. Furthermore, surface-accumulation patterns of the total amounts of these heavy metals could be observed in both habitats, and the availabilities of these elements were higher in deeper soils. Reclamation also had significant impacts on the vertical distribution of Cu, Pb, Cd, and Zn. It is essential to properly monitor nearby aquacultural activities, freshwater irrigation, and traffic pollution during plant harvest to alleviate the negative effects of these human activities.

“…These soils are under intense pressure from various anthropogenic sources of pollutants, which could contribute significantly to multiple stress conditions (Navarro-Ortega et al 2015;Wang et al 2015). In fact, as a complex and dynamic component of aquatic ecosystems, riparian soils are a suitable medium for monitoring heavy metal pollution.…”

Purpose Riparian zone contamination is a growing problem for several European catchments due to high anthropogenic pressures. This study investigates As, Cd, Cr, Cu, Ni, Pb, and Zn concentrations in the Sava River riparian zone, characterized by wide agricultural areas, various geological substrates, and different types of industrial pollution. The accumulation and mobility of these elements were studied because they are listed as priority substances in the Water Framework Directive and environmental objectives for surface waters. Materials and methods Sampling was performed during the sampling campaign of the EU 7th FW-funded GLOBAQUA project in September 2015 during a low-water event. Soil samples were collected along the Sava River at 12 selected sampling sites, from a depth of 0–30 cm, at a distance of 10–15 m from the river bank. The extent of pollution was estimated by determining total and readily soluble element concentrations in the soils. Potential ecological risk and the source of the selected elements in the soils was determined using the enrichment factor (EF), potential ecological risk index (RI), and statistical methods such as the principal component analysis (PCA) and multiple linear regression analysis (MLRA). Results and discussion This study showed that concentrations of the selected elements increase along the Sava. In terms of origin, PCA and MLRA indicated that Cr and Ni in soils are predominantly lithogenic, while As, Cd, Pb, and Zn are both lithogenic and anthropogenic (ore deposits, industry, and agriculture). PCA singled out Cu since its origin in soil is most probably from specific point-source pollution. EF was generally minor to moderate for most of the examined elements, apart from Cu, for which the EF was significant at one sampling site. Overall ecological risk (RI) fell within the low-risk category for most sites, apart from Belgrade sampling site (BEO), where high total Cd content affected individual and overall ecological risk indicators, indicating Cd could represent a considerable ecological risk for the downstream riparian zone. Conclusions At downstream sites, there was a noticeable increase in PTE content, with Cd, Cr, Ni, and Zn exceeding the proposed threshold values for European soils, indicating rising contamination in riparian soils. In terms of the ecological risk, only Cd could pose a potential ecological threat for the downstream riparian zone.
