“…Previous research investigated the dangers of heavy metal to human health as well as environmental remedies. Wang et al [10] analyzed the sediments near the Shekou Industrial District's exit and discovered that zinc (Zn), copper (Cu), cadmium (Cd), and mercury (Hg) were mostly derived from effluent from the electroplating, metal, and battery industries. Using polluted wastewater for irrigation, Xiao et al [11] investigated the distribution of heavy metals in the vegetable and paddy crops near an electroplating facility.…”

Heavy metals in groundwater and soil are toxic to humans. An accurate risk assessment of heavy metal contamination can aid in environmental security decision making. In this study, the improved ecological risk index (RI) is used to comprehensively investigate the influence of heavy metals in soil and groundwater within electroplating factories and their surrounding regions. In the non-overlapping area, the RI of soil and groundwater is computed individually, and in the overlapping area, the greater RI of soil and groundwater is employed. Two typical electroplating factories are used to examine the heavy metal distribution pattern. The heavy metal concentrations are compared between Factory A, which is in operation, and Factory B, which is no longer in operation, in order to analyze the heavy metal concentrations and associated ecological risks. Heavy metals continue to spread horizontally and vertically after Factory B was closed. Heavy metal concentrations in groundwater surrounding Factory B are substantially greater, and the maximum concentration exists deeper than in Factory A. Because Cr, Cu, and Hg in soil contribute significantly to the RI, the primary high RI region is observed at Factory A and the region to the southwest. The RI of Factory B demonstrates a broad, moderate risk zone in the west and southwest.

“…Since heavy metals exist in both solid and dissolved forms, they have a significant impact on many geochemical and biological cycles. Marine sediments are reservoirs of heavy metals and other hazardous pollutants along with terrestrial particles and shell debris (Wang et al, 2020). They can be used to determine the source of toxic substances, identify pathways for diffusion, and identify drains of pollutants in aquatic systems (Vasiliu et al, 2020).…”

This study aimed to estimate the contamination levels and potential risks of some heavy metals (Al, Fe, Mn, Zn, Cu, Co, Ni, Pb, and Cd) in surface sediments collected from northern Safaga Bay along the Egyptian Red Sea coast. The concentrations of the studied metals decreased in the following order: Al> Fe> Mn> Zn> Pb> Ni> Co> Cu> Cd, with average concentrations of 4537.12±5025.35 mg/kg dw, 678.91±342.97 mg/kg dw, 136.09±117.00 mg/kg dw, 40.38±11.92 mg/kg dw, 17.19±3.97 mg/kg dw, 12.74±3.01 mg/kg dw, 9.24±2.19 mg/kg dw, 2.98±1.24 mg/kg dw, and 2.46±1.20 mg/kg dw, respectively. Results of sediment contamination indices such as contamination factor (CF), degree of contamination (C d ), modified degree of contamination (mC d ), metal pollution index (MPI), enrichment factor (EF), potential contamination index (PCI i ), sediment pollution index (SPI), and potential ecological risk index (RI) showed that the sampling sites are rated between uncontaminated and highly polluted. According to sediment quality guidelines (SQGs), adverse biological effects of heavy metals have sometimes been associated with Cd, and more rarely with Zn, Cu, Ni and Pb. Interestingly, sediment quality indices indicated the critical hazards of Cd to the biological system in the study area. The results of the assessment of risks to human health by heavy metals in sediments demonstrated that their exposure did not pose any carcinogenic risks. Statistical analyses revealed the interaction between geochemical variables, the distribution of heavy metals, as well as the proximity to pollution sources and flowing water.
