“…These results consistent with previous studies such as Elizabeth Botte et al [24] also reported a significant positive correlation between pH and the Pb in sediments within the Bahia Blanca Estuary. These results were also consistent with previous reports by Sun et al [73] and Tian et al [74], as reported significant negative associations between pH and metal levels in sediments.…”

“…Marine environments receive trace metals from both natural leaching continental progressions as well as mining, industrial, and urban activities. Coastal sediments, particularly organic-rich sediments that have high potential to accumulate contaminants, act as a primary sink and substantial source of many pollutants [15,18,74]. In fact, sediments are a significant carrier for trace metals in marine environments, and heavy metals may be transported into these environments associated with deposits.…”

In the Anthropocene era, an immersion of toxic substances, i.e., trace metals, has been enhanced in the marine environment not only due to urban sprawl and industrial development but predominantly owing to incongruous management and lack of sustainable approaches. The coastal region of Pakistan shares a similar obstacle as most of the developing countries confronted. Therefore, this study was designed to investigate concentrations of eight metals (Cu, Fe, Zn, Ni, Co, Pb, Cr, and Cd) in sediment and Dotillid crab, Ilyoplax frater, at three tidal creeks in Karachi, Pakistan. All metals in sediments and crabs were analyzed by atomic absorption spectrometer. The sediment pollution was evaluated by contamination degree (CD) and potential ecological risk index (RI). After depicting the metal pollution in sediments, metal accumulation, and contamination in benthic crab were investigated through total metal concentrations in crabs, accumulation factor (AF), correlation analysis, and regression analysis. The results exhibited substantial differences in the concentrations of Zn, Ni, Pb, Cr, and Cd among the tidal creek sediments. Contamination factors indicated that the Cd and Pb had the highest sharing in sediment pollution, and the tidal creeks classified as moderately contaminated. All metal accumulations in Dotillid crabs showed notable spatial variations, and accumulation factors (AFs) for most of the metals were > 1.0, signifying the strong bioaccumulation of metals in crabs. Particularly, Cu, Co, and Cd levels were considerably greater (two to three times) in Dotillid crabs compared to creek’s sediments, even though they don’t share any relationship between two matrixes. Hydrographical and sedimentological traits also revealed significant interactions with metal levels in sediments and crabs. A substantial association was also noticed in Fe, Ni, and Pb between sediments and crabs. Interestingly, most of the metal AFs showed a notable inverse correlation with the environmental matrix. Exceptionally, a strong positive correlation found between the Pb concentration in crabs and sediments suggested that I. frater probably acts as an indicator of Pb pollution.

“…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.…”

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

The influence of salinity on the single and binary sorption of Ni and Zn onto iron oxide- and manganese oxide-coated sand (IOCS and MOCS) was investigated at pH = 5. The single sorption experimental data were fitted to Freundlich, Langmuir, Dubinin–Radushkevich, and Sips models, and a nonlinear sorption isotherm was observed (NF = 0.309–0.567). The higher Brunauer–Emmett–Teller (BET) surface area (ABET) and cation exchange capacity (CEC) of MOCS contributed to the higher maximum sorption capacities (qmL) of Ni and Zn than that of IOCS. The Ni sorption capacities in the single sorption were higher than that in the binary sorption, while the Zn sorption capacities in the single sorption were less than that in the binary sorption. The single and binary sorptions onto both IOCS and MOCS were affected by the salinity, as indicated by the decrease in sorption capacities. Satisfactory predictions were shown by the binary sorption model fitting including P-factor, ideal adsorbed solution theory (IAST)–Freundlich, IAST–Langmuir, and IAST–Sips; among these, the P-factor model showed the best fitting results in predicting the influence of salinity of Ni and Zn in the binary sorption system onto IOCS and MOCS. IOCS and MOCS offer a sustainable reactive media in a permeable reactive barrier (PRB) for removing Ni and Zn in the presence of salinity.

“…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).…”

Xinfengjiang Reservoir (XFJR) is the largest drinking water source in the southern China, and plays a vital role in supporting the development of China's Pearl River delta. The levels, source identification, potential ecological risks and health risk of eight metal elements including Zn, Pb, Ni, Mn, Cu, Cr, Cd and As in the sediments of the XFJR and Heyuan section of the East River (HYER) were investigated.
