Heavy metal(loid)s (HMs) play an important role in economic development since they are used various branches of industry. However, all industrial activities emit HMs into the environment, where no longer useful but potentially toxic. It has been observed that enter soil and sediment, potential human health risk may arise due to their excessive accumulation. Having mind importance assessing these media, we analyzed published works last decade created a summary exposure factors models for sediment. This analysis revealed remarkable increase number publications about assessment HMs, especially few years. Since many differences values distributions were noted, this study focused on elucidating differences. Non-carcinogenic carcinogenic evaluated through deterministic approach is prevalent use, probabilistic one, which gaining more attention research. In end, guided by studied literature, propose factors.

Plant cultivation can influence the immobilization of heavy metals in soil. However, roles soil amendments and microorganisms crop-based phytoremediation require further exploration. In this study, we evaluated impact Zea mays L. cultivation, biochar application, arbuscular mycorrhizal fungi (AMF) inoculation on lead (Pb) immobilization. Our results indicated that addition resulted a significant, 42.00%, reduction AMF colonization. inoculation, all contributed to enhanced Pb immobilization, as evidenced by decreased levels diethylenetriaminepentaacetic acid- CaCl2-extractable Furthermore, subjected plant with displayed reduced concentrations bioavailable Pb. Biochar altered distribution fractions soil, transforming acid-soluble form into relatively inert reducible oxidizable forms. Additionally, biochar, AMF, their combined use promoted maize growth parameters, including height, stem diameter, shoot root biomass, phosphorus uptake, while simultaneously reducing concentration. These findings suggest synergistic effect phytostabilization. summary, despite adverse growth, cultivating concurrent emerges recommended effective strategy for phytoremediation.IMPORTANCEHeavy metal contamination is pressing environmental issue, has emerged sustainable approach mitigating problem.

Heavy metal contamination in soil is a global issue threatening human health and ecosystems. Accurate spatial maps of heavy metals (HMs) are vital to mitigating the adverse effects on ecosystem. This study utilizes GIS multivariate analysis evaluate HMs agricultural soils from Al Ghat Governorate, Saudi Arabia, analyzing Al, As, Co, Cr, Cu, Fe, Mn, Ni, Pb, V, Zn using ICP-AES 35 samples. Methods included factor (CF), enrichment (EF), risk index (RI), geoaccumulation (Igeo), pollution load (PLI), quality guidelines (SQGs), analysis. The soils, characterized by sandy texture, low organic matter, alkalinity due arid conditions high calcium carbonate, had following HM concentrations (mg/kg) descending order: Fe (11,480) ˃ (7786) Mn (278) (72.37) Ni (28.66) V (21.80) Cr (19.89) Co (19.00) Cu (12.46) Pb (5.46) As (2.69). EF, CF, Igeo suggest natural sources for most HMs, predominantly sedimentary sequence, with localized Zn, linked mixed influences. PLI RI indicated acceptable levels, posing no ecological risk. All samples fell below SQG thresholds confirming minimal threat. Statistical highlighted cover as primary source, activities contributing levels.

Heavy metal(loid) pollution poses a serious threat to the health and habitability of ecosystems worldwide. This study aims investigate concentration, degree, sources, risks heavy metal(loid)s (HMs) in soil Shanxi Province, China. The concentrations Cu, Ni, Cd, Pb, Hg As were measured by ICP-MS 146 samples collected from agricultural land. degree ecological HMs analyzed variety indexes, human assessed using USEPA model. Results showed average 1.08, 1.15, 1.44, 1.50 1.25 times higher than background values investigated areas soil, respectively. contamination factors revealed moderate Hg, As, Cd Cu areas, load index indicated considerable contamination. Nemerow low severe with compound HMs. potential risk indicates that pose ecology. Coal mining was primary sources identified ACPS-MLR. Soil (75.11%) Ni (62.33%) mainly derived coal mining, Pb (73.13%) traffic emissions. (38.60%) originated combustion. associated these due exposure found be within acceptable levels for adults. concentration imposes strongest effect on non-carcinogenic analysis different exposed populations. In conclusion, moderately threatens ecology, but there no significant study. Furthermore, this reveals which is helpful managing contaminated region.

Understanding the factors that controlling agricultural soil heavy metals/metalloids distribution is vital for cropland remediation and management. For this objective, 227 soils were sampled in Guanzhong Plain, China, to measure concentration of five metals (Pb, Cd, Ni, Zn, Cu) one metalloid (As) by X-ray fluorescence spectrometer, meanwhile, 24 possible influencing metals/metalloid collected grouped into three categories. A sequential multivariate statistical analysis was carried out provide insight distribution, then stepwise multiple linear regression (SMLR) partial least squares (PLS) used predict concentrations based on result identification. The results demonstrated types land use did not have a substantial effect except Zn Cu. properties category played major role concentration. Mn Fe, which are main constitute elements inorganic colloid, most significant factors, followed P, K Ca. Soil pH organic matter (SOM) content, often considered as important present study. SMLR more effective than PLS predicting content. study enlighten future contamination treatment regions with high low SOM content should concentrate colloid particles, strong adsorption capacity environmentally friendly.
