Heavy metal pollution is one of the negative impacts deriving from municipal solid waste landfills. Due to the multiple pollution transport pathways (including leachate, runoff, and waste gas) and complex and co-existing potential pollution sources (such as agricultural activities) around landfills, a combination of different pollution assessment methods and source identification tools are required to address pollution distribution and potential risks. In this study, the distribution of eight heavy metals (chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), zinc (Zn), arsenic (As), cadmium (Cd), and mercury (Hg)) around a landfill were analyzed using 60 topsoil samples. There are no environmental pollution and human carcinogenic risk posed by the heavy metals for the time being. However, high concentration of Cr in soil would cause non-carcinogenic risk for adults in the study area. Besides, the geoaccumulation indices of Cr, Cu, Ni, Zn, As, and Hg confirmed anthropogenic accumulation of these heavy metals in soils. Additionally, the potential ecological risk index indicated that Hg posed considerable risk to the eco-environment around the landfill. Sources of the heavy metals in the study area were attributed to natural sources (22.1%), agricultural activities (27.6%), and the landfill (50.3%). As the greatest contributor, the landfill affected heavy metal distribution in nearby surface soils mainly via surface runoff and waste gas. The continuous accumulation of heavy metals and non-carcinogenic risk for adults suggests the necessity for continuous monitoring of heavy metal content and migration around the landfill. This study provides a reference for local authorities in the study area.

Aquatic environments (e.g., lakes [5], rivers [6], reservoirs [7], and wetlands [8]) receive heavy metals in untreated or inadequately treated wastewater from domestic, industrial, and agricultural sources. Pollution from heavy metals is inflicting rivers worldwide [9,10], especially in developing countries [11,12].…”

Risk assessment of heavy metals in the surface sediment at the drinking water source of the Xiangjiang River in South China

et al. 2020

Background: The Xiangjiang River is an important drinking water resource for the Hunan Province of China. It is crucial to ascertain the pollution status, influencing factors, ecological risks, and possible sources of heavy metals in the sediments of the Xiangjiang River. Sediment is both a source and a sink of heavy metals in aquatic ecosystems. In this study, surface sediment was collected from the Zhuzhou Reach of the Xiangjiang River and eight heavy metals were investigated. Results:In all sediment samples, all eight heavy metals were detected and their average concentration fell in the order of Zn > Pb > As > Cu > Cr > Ni > Cd > Co. Assessment shows extremely serious Cd pollution and a very high potential ecological risk from Cd. According to correlation analysis and principal component analysis (PCA), As, Cu, Ni, Pb, and Zn originate from industrial wastewater and mineral smelting activities, whereas Co, Cr, and Ni come from natural sources. Redundancy analysis (RDA) reveals that the organic matter content and the particle size of the sediment have a certain influence on the enrichment of heavy metals. Conclusion:Among all eight examined heavy metals in the surveyed area, the content of Zn, Pb, and As is the highest, and that of Cd and Co is the lowest. Despite a low level of absolute content, the Cd in sediment already renders a high ecological risk and thus calls for urgent attention. Anthropogenic activities are the main source of heavy metals in the sediment. The distribution of heavy metals may also be influenced by sediment properties. The results provide guidance for controlling heavy metal pollution and protecting drinking water sources in the Xiangjiang River.

The primary focus of this research was the chemical fractionation of potentially toxic elements (PTEs) and their presence in several industrialised cities in Serbia. Furthermore, their origin, contamination levels, and environmental and human health risks were assessed. The results indicated that the examined soils were characterised by slightly higher Cu, Ni, Pb, and Zn levels than those set by European and national regulations. These elevated Cu, Pb, and Zn concentrations were caused by intensive traffic and proximity to industry, whereas the higher Ni levels were a result of the specific geological substrate of the soil in the study area. The environmental risk was found to be low and there was no enrichment/contamination of the soil with these elements, except in the case of Pb, for which moderate to significant enrichment was found. Lead also poses a potential non-carcinogenic risk to children through ingestion and requires special attention due to the fact that a significant proportion of this element was present in the tested soil samples in a potentially available form. Analysis of the health risks showed that children are more at risk than adults from contaminants and that ingestion is the riskiest exposure route. The carcinogenic risk was within the acceptable limits.
