“…Geostatistics is extensively used to assess the level of soil contamination and estimation of risk in contaminated sites by preserving the spatial distribution and uncertainty of the estimates. In addition, geostatistics and GIS provide useful tools for the study of spatial uncertainty and hazard assessment (McGrath et al 2004;Komnitsas and Modis 2006;Reza et al 2013).…”

The spatial distribution and hazard assessment of heavy metals in the soils of surrounding agricultural fields affected by mine drainage of Ledo coal mining area of Tinsukia district, Assam, India, were investigated using statistics, geostatistics and geographic information system techniques. The amounts of Cr, Cd, Ni and Pb were determined from 83 soil samples collected within the contaminated area. The maps based on ordinary kriging showed that high concentrations of heavy metals were located in the low-lying paddy field and near coal mining site. Indicator kriged probability maps were prepared based on the concentrations to exceed permissible limit (MPL). It was seen that more than 95 % of the studied area has a higher than 50 % probability to exceed the MPL value of Pb and Ni. Multivariate statistical analyses and principal component analysis suggest that Cd and Pb are derived from anthropogenic sources, particularly coal mining activities, whereas Ni and Cr are derived from lithogenic and/or anthropogenic sources.

“…Hence, data gaps showing the concentrations origin and associated risks of metals in soil depths from abandoned sites with different landuse. Over the years, several human and environmental health concerns about metals inputs in soils [12][13][14][15][16][17][18]. The concentrations of metals in abandoned sites are vital for evaluating the sources and human and environmental health hazards on the immediate and adjacent environment matrices.…”

This study provides a comparative assessment of cadmium (Cd), lead (Pb), chromium (Cr), nickel (Ni), copper (Cu), manganese (Mn), zinc (Zn), and iron (Fe) pollution occurrence, sources, and exposure risk in soils from selected abandoned sites. The concentrations of metals were determined using atomic absorption spectrophotometry. The metals occurrence ranged from 0.02 (Zn) to 16600 mg kg−1 (Fe) in the order of subsoil > topsoil with petroleum tank farm and fuel/gas service station exhibiting high metal loading. The sources of metals are anthropogenic and geologic. The hazard index values for infants’ were higher than that of adults, and the inhalation risk for adults’ was considerably higher than for infants’ exposure. The ecological risk of Cd, Pb, Cr, Ni, and Zn falls in the contamination to pollution index. This study revealed the need for clean-up and restoration of abandoned site soils.

“…Among various organic and inorganic pollutants, potentially toxic metal ions are of high threat (Tchounwou et al 2012;Masindi & Muedi 2018). Municipal waste (Ishchenko 2019), fertilizers (Cheraghi et al 2013), fossil fuel (Kamran et al 2013), mining and smelting of metallic ferrous ores (Fashola et al 2016), pesticides (Defarge et al 2018), sewage sludge (Shamuyarira & Gumbo 2014), battery processing (Khan et al 2020), textile printing (Velusamy et al 2021), paper industries (Reza et al 2013) and leather industries (Abbas et al 2012) are the primary contributors to potentially toxic metals in freshwater resources. Potentially toxic metals such as Cu, Zn, Hg, Ni, Pb, Cd, As and Cr are non-biodegradable and accumulate in living beings (Fu & Wang 2011;Chowdhury et al 2018Chowdhury et al , 2021Gupta et al 2021a).…”

In recent research, the composite of Fe3O4 and metal-organic frameworks have shown great potential in removing potentially toxic metals from water. We conducted the adsorption studies of potentially toxic metal ions (Cu2+, Co2+ and Cd2+) using the composite of Fe3O4 and zeolitic imidazole framework-8 (Fe3O4@ZIF-8) for the first time. The solvothermal technique was used to synthesize the Fe3O4. The magnetic ZIF-8 offers high thermal stability, greater adsorption surface, good removability, and high chemical and thermal stability. Characterization techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS) and Fourier-transform infrared spectroscopy (FTIR) were used to characterize the synthesized samples. The SEM and XRD results revealed the high purity and structural integrity of ZIF-8 crystallites. To remove potentially toxic metals (Cu2+, Co2+ and Cd2+), the influence of adsorbent dosage, contact time, pH, and adsorbate concentration on the adsorption performance of Fe3O4@ZIF-8 was investigated. Langmuir isotherm accurately represented the adsorption processes, with absorption magnitudes of Fe3O4@ZIF-8 determined to be 46.82 mg g−1, 71.29 mg g−1 and 54.49 mg g−1 for Cu2+, Co2+ and Cd2+, respectively. According to the adsorption mechanism analysis, the primary Cu2+, Co2+ and Cd2+ removal methods of Fe3O4@ZIF-8 were ion exchange and coordination bonds. The uptake capacity of Cu2+, Co2+ and Cd2+ solution by Fe3O4@ZIF-8 were not significantly affected by the presence of counter ions. The material exhibited superior regenerative properties for Cu2+, Co2+ and Cd2+ ions from the water up to three cycles. This study concluded that the Fe3O4@ZIF-8 could be a viable candidate for eliminating potentially toxic metals (Cu2+, Co2+ and Cd2+).
