Accumulation and ecological risk of heavy metals in soils along the coastal areas of the Bohai Sea and the Yellow Sea: A comparative study of China and South Korea

The Influence of Salinity on the Removal of Ni and Zn by Sorption onto Iron Oxide- and Manganese Oxide-Coated Sand

“…The health risks of Ni and Zn are categorized as high based on the cancer risk and hazard quotients evaluation above the Ni and Zn threshold concentration (>3000 µg L −1 ) [1,4,5]. Recently, Tian et al [6] and Liu et al [7] reported the significant contribution of industrialization to the increase in Ni and Zn contaminations in water sources in China and Korea, two heavily industrialized countries where 70-75% of major cities and industries are located in the coastal regions. Attempts to treat Ni and Zn contamination in coastal groundwater are crucial since the economic growth of these two countries, especially Korea, is highly dependent on industrial development alongside the coastal area.…”

Heavy Metals and Arsenic in Sediments of Xinfengjiang Reservoir in South China: Levels, Source Identification and Health Risk Assessment

“…The lowest and highest CVs, which were those for Zn and As, respectively. The high CVs found for some HMs indicated that the concentrations of these metals differed greatly at different sites, suggesting that they are likely affected by multiple anthropogenic activities (Liu et al, 2020). The I geo was calculated and is presented in Table 2.…”

“…With the acceleration of urbanization process and the increase of human activities, heavy metal (HMs) pollution has caused great environmental concern and become a risk to ecosystem and public health (Sun et al, 2019;. Human activities produce industrial emissions, municipal waste disposal, and abusive usage of chemical fertilizers and pesticides, leading to an accumulation and sink of HMs in various environmental media (Liu et al, 2020), including sediment which is commonly known to be the major source for HMs (Huang, 2019;Tian et al, 2020). Heavy metals can be released through a series of physical, chemical and biological processes and entered into interstitial and overlying water, resulting in "secondary contamination" (Zhang et al, 2018;Yang et al, 2016).…”

“…Previous studies show HMs in sediments mainly derive from the long-term effects of natural factors and human production activities including mining activities, agriculture fields, and atmospheric deposition (Chen et al, 2019;Kang et al, 2019). When environmental conditions change, these sediments can also be potential sources of HMs for various aquatic organisms, allowing HMs to enter the food chain (Liu et al, 2020;Zhuang et al, 2019), leading to serious health threat to benthos, aquatic plants and animals, and human (Chon et al, 2012;Yao et al, 2006), due to the high toxicity, non-degradability of HMs to organisms . Exposure to Cd mainly leads to kidney damage, chronic cadmium poisoning.…”

Ecological modeling based on benthic foraminifera from Tupilipalem coast, southeast coast of India: Implications for ecological trajectory

“…Over the last few decades, anthropogenic influx of heavy metals into the aquatic ecosystem has increased to alarming magnitude (Ansari et al, 2003;Gheorghe et al, 2017;Pandey & Singh, 2017;Cardoso et al, 2019;Reid et al, 2019). As a result, ecosystems have chronic inputs of metals thus contaminated sediments heavily (Qian et al, 2015;Soliman et al, 2015;Liu et al, 2020;Tian et al, 2020).The consequence of the non-degradable state of heavy metals, causes for bioaccumulation in the food chains (Singh et al, 2011). This work aims to propose a model to understand the impact of coastal morphological changes on the lagoon mouth by affecting the concentrations of heavy metal in the sediments and taxonomic composition, quantitative distribution and test morphologies of benthic foraminifera.…”
