“…The bioaccumulation process shows absorption, accumulation, and utilization of contaminants from sediments following a root system and surface area (Chai et al 2020, Ma et al 2019). This activity reduces toxic effects using dilution and translocation to death organs (Alzahrani et al 2018, Xie et al 2020) and organic absorption (Nour et al 2019, R. Xiao et al 2015. However, translocation refers to moving contaminants between the cell and the vascular tissue to be distributed in the stem, leaves, and other organs.…”

Mangrove has ability to reduce impact of heavy metal contaminant released from industry and domestic waste. . Therefore, this study aimed to analyze interpolation and clustering of heavy metal accumulation and traslocation in mangrove ecosystem.. The results showed the accumulation of Mercury in water, stem and bark, leaves, and roots were 0.1347±0.0212 ppm, 0.0137±0.0137 ppm, 0.0110-0.0640 ppm, 0.0020-0.0120 ppm, and 0.0260-0.0690 ppm. Cadmium accumulations between 1.6048±0.3595 ppm, 0.0292±0.0047 ppm, 0.0790-0.2650 ppm, 0.0130-0.0480 ppm, and 0.1560-0.2300 ppm. Furthermore, Zinc had score that were 35.1746±5.4856 ppm, 0.0550±0.0095 ppm, 10.3250-32.4490 ppm, 7.1200-23.4150 ppm, and 16.7170-39.1200 ppm. However, bioaccumulation factors of Hg ranged between 0.0210-0.4751, Cd 0.0105-0.1541, and Zn 0.2807-1.2506 with the translocation factors of 0.0459-1.0547 (Hg), 0.0642-1.3855 (Cd), and 0.4086-1.3057 (Zn). The mangrove landscape showed that of Sonneratia alba (best of Hg accumulation), Rhizophora mucronata (best of Cd accumulation), Avicennia marina (best of Zn accumulation)

“…Heavy metals (HMs) are an environmental threat and are of grave concern worldwide [1]. Rapid industrialization and urbanization have caused heavy metals to contaminate the atmosphere and it is a problem for human health [2][3][4]. HMs poses a major environmental threat to living organisms and habitats due to their non-biodegradability, bioaccumulation, environmental stability, persistence and biotoxicity characteristics [5][6][7].…”

“…geological weathering, atmospheric precipitation, wave erosion, wind and bioturbation) and anthropogenic activities (e.g. rapid industrialization, urbanization, agricultural runoff and transport) play a key role in the spread of HMs to the marine habitats of aquatic ecosystems such as rivers and estuaries [2,4,14]. In addition, human activities that can produce industrial pollution, the deposition of urban waste and the offensive use of chemical fertilizers and pesticides result in the accumulation and sinking of HMs in aquatic habitat surface sediments [15][16][17].…”

Heavy Metals - Their Environmental Impacts and Mitigation

View full text Add to dashboard Cite

Heavy metals (HMs) are natural environmental constituents, but their geochemical processes and biochemical equilibrium have been altered by indiscriminate use for human purposes. Due to their toxicity, persistence in the environment and bioaccumulative nature; HMs are well-known environmental contaminants. As result, there is excess release into natural resources such as soil and marine habitats of heavy metals such as cadmium, chromium, arsenic, mercury, lead, nickel, copper, zinc, etc. Their natural sources include the weathering of metal-bearing rocks and volcanic eruptions, while mining and other industrial and agricultural practices include anthropogenic sources. Prolonged exposure and increased accumulation of such heavy metals may have detrimental effects on human life and aquatic biota in terms of health. Finally, the environmental issue of public health concern is the pollution of marine and terrestrial environments with toxic heavy metals. Therefore, because of the rising degree of waste disposal from factories day by day, it is a great concern. Pollution of HMs is therefore a problem and the danger of this environment needs to be recognized.

“…An estimated 6.24% or 137,000 km 2 of European agricultural lands are destroyed by heavy metals and need urgent remediation (Tóth et al, 2016). A number of previous studies have shown that the Ni 2+ contamination of Egyptian soils due to anthropogenic and natural sources endangers the agroecosystem (El-Gammal, Ali & Samra, 2014;Hashim et al, 2017;Nour et al, 2019).…”

Background Untreated wastewater carries substantial amount of heavy metals and causes potential ecological risks to the environment, food quality, soil health and sustainable agriculture. Methodology In order to reduce the incidence of nickel (Ni2+) contamination in soils, two separate experiments (incubation and greenhouse) were conducted to investigate the potentials of rice straw biochar and elemental sulfur in remediating Ni2+ polluted soil due to the irrigation with wastewater. Five incubation periods (1, 7, 14, 28 and 56 days), three biochar doses (0, 10 and 20 g kg−1 of soil) and two doses of sulfur (0 and 5 g kg−1 of soil) were used in the incubation experiment then the Ni2+ was extracted from the soil and analyzed, while ryegrass seeds Lolium perenne L. (Poales: Poaceae) and the same doses of biochar and sulfur were used in the greenhouse experiment then the plants Ni2+-uptake was determined. Results The results of the incubation experiment revealed a dose-dependent reduction of DTPA-extractable Ni2+ in soils treated with biochar. Increasing the biochar dose from 0 g kg−1 (control) to 10 or 20 g kg−1 (treatments) decreased the DTPA-extractable Ni2+ from the soil by 24.6% and 39.4%, respectively. The application of sulfur increased the Ni2+-uptake by ryegrass plant which was used as hyper-accumulator of heavy metals in the green house experiment. However, the biochar decreased the Ni2+-uptake by the plant therefore it can be used as animal feed. Conclusions These results indicate that the biochar and sulfur could be applied separately to remediate the Ni2+-contaminated soils either through adsorbing the Ni2+ by biochar or increasing the Ni2+ availability by sulfur to be easily uptaken by the hyper-accumulator plant, and hence promote a sustainable agriculture.
