“…Each SOM matrix mapping represents a component value of 110 reference vectors. On the component plane, similar color gradients indicate a positive correlation between variables, and the sources of heavy metals may be the same [ 33 ]. It can be seen from Fig.…”

Metal pollution of river sediments in industrial areas has attracted widespread attention. In this study, 11 metal ions (including Fe, Al, Ag, Mn, Cd, Cr, As, Cu, Pb, Zn, Ni) were determined and analyzed in river sediments of typical industrial areas in the Kuye River Basin, a first-level tributary of the Yellow River. The geological accumulation index, enrichment factor, and pollution load index indicated that the metal ions in this area were enriched and polluted to different degrees. The spatial distribution of the 8 kinds of heavy metals showed that the content in the upstream and downstream was higher, and the middle reaches were lower. the heavy metals mainly came from local industrial activities, coal mining and transportation, and soil weathering, Human activities were the main reasons for the dramatic spatial changes and high levels of heavy metals. The results of the combined potential ecological risk index and sediment quality guidelines showed that the ecological risk downstream of the area was high, and Ni and Pb have caused adverse biological reactions. The human carcinogenic risk assessment result showed that the non-carcinogenic hazard quotient of metal ions in the study area was at an acceptable level, but the carcinogenic risk level of Ni and Cr was higher than 10-4, which was an unacceptable level and must be got enough recognition. The results of this study can provide theoretical support for the pollution control and environmental restoration of rivers in energy-enriched areas.

“…Those pollutants it is excreted into the environment for disposal and then accumulate over time to concentrations that exceed limits allowed under international laws (Hawal et al, 2021c;Faisal et al, 2015). Heavy metals affect not only food and soil security, but also human health through the food chain (Xu, Y et al, 2022). Parent soil's material governs the heavy metals which are affected by physico-chemical properties of the soil and the administration practices of the crop (Srinivasarao et al, 2014).…”

Remediation of arsenic-contaminated soil by the technique of electro-kinetic using various enhanced conditions is the thrust of this study. Many tests were performed with different operating conditions such as the electrodes solution (tap water) with a variable pH at (2, 5, and 8). Cyclodextrin (10% hydroxypropylbeta-cyclodextrin or HPCD) has been used as an activating agent that helps enhance this process of soil arsenic clean-up. Agricultural wastes (pomegranate peels) were used after treating them as an adsorbent to impede the return of pollutants to the soil as a result of reverse osmosis. The obtained results after the remediation completion indicated that the best elimination capacity was 72% at a pH of 2. This indicates that the elimination capacity increases with decreasing pH of the electrodes solution. Mixing the HPCD solution with soil as an enhanced solution increased the solubility and desorption of arsenic from the soil. Then, arsenic-containing HPCD micelles readily moved to the cathode electrode by electro osmotic ow, and the elimination capacity increased (84%). It was concluded that pomegranate peels are a good adsorbent for arsenic returning to the soil during the treatment process as a result of reverse osmosis. Hence, the application of this material in this research gave a perfect impression of its use as an inexpensive, environmentally friendly adsorbent and an alternative to commercial absorbents.
