Potential Ecological Risk Assessment Of Heavy Metals In Sediments A In this study, we also tried to figure out how irrigation water, such as well water with chemical fertilizers (wwf), treated wastewater effluent (twe), and river water (rw), affects the number of heavy metals in soil vegetable culture. Heavy metals accumulation in soils, sediments and their subsequent release to ground or surface water poses an environmental threat.
Ecological Risk Warning Assessment Of Heavy Metals In The Study Area The soil environment is vital for human survival and sustainable development [1,2,3].however, soil environmental problems have become a significant issue worldwide due to intense human activities, especially agricultural activities [4,5].agricultural processes, including excessive use of fertilizers and pesticides, have accelerated soil degradation, leading to the enrichment of heavy metals. Ef analysis suggested that anthropogenic sources contributed to elevated hm levels, including port activities and agricultural runoff. ecological risk index (ri) analysis revealed moderate risk in 40% and considerable risk in 20% of sampling locations. The results show that the risk level of 3 44 for cd (6.82%) has reduced from the disastrous risk to high risk level, and 38 44 for ni (86.36%) has reduced from a moderate risk level to a low risk level, but the risk level of 4 44 for hg (9.09%) has increased from a low risk level to a moderate risk level . as a scale for calculating pollution. The urban–rural interface represents a critical ecological zone where anthropogenic activities intersect with agricultural systems, creating complex challenges for trace element dynamics and human health. this study comprehensively investigated the metabolic pathways, bioaccumulation mechanisms, and potential health risks associated with heavy metal accumulation in vegetables from water.

The urban–rural interface represents a critical ecological zone where anthropogenic activities intersect with agricultural systems, creating complex challenges for trace element dynamics and human health. this study comprehensively investigated the metabolic pathways, bioaccumulation mechanisms, and potential health risks associated with heavy metal accumulation in vegetables from water. A comprehensive analysis of eight metals (fe, mn, cu, ni, zn, cr, pb, and cd) in 38 surface sediment samples from the henan region of the yellow river was conducted to describe the grade, risk assessment, and sources of heavy metals (hms) contamination. the average concentration of hms was fe> mn> zn> cr> ni> cu> pb> cd. Accumulation of heavy metal pollution in sediment over an extended period significantly impacts aquatic organisms, emphasizing the imperative need for a thorough assessment of sedimentary heavy metal pollution. The tibetan plateau, a globally significant ecological region, is experiencing escalating pollution from heavy metals (hms). this study applies a machine learning approach based on the self. Heavy metal pollution is hidden, permanent and irreversible due to the basic character of heavy metals, such as accumulation, persistence and low mobility in soils.
