Heavy metal (HM) pollution in agricultural soils represents a hidden danger to food security worldwide. In this paper, the spatio-temporal trends of heavy metals from eight countries and 50 soil samples farmland were evaluated through combination field surveys meta-analysis provide comprehensive report on pollution. The analysed using inductively coupled plasma–mass spectrometry (ICP-MS) (Perkin Elmer Nixon 300Q). contamination factor (CF) load index (PLI) calculated. results CF indicate extreme for Cr, suggesting ecotoxicological effects, while PLI values range baseline moderate Cd, Hg, Cu, Zn, Ni, except which shows very high pollution, that oils have undergone some form deterioration. reviewed articles published between 2010 2023 showed increasing all HMs. weighted mean As, Ni 0.0-222.7, 0.08-289.2, 0.03-193, 2.94-198.1, 0.0-771.1, 0.0-231, 1.71-99.75.6 mg/kg, respectively. Zn As exceeded two three times China National Environmental Monitoring Centre (CNEMC) European Union's most cited guideline (MEF), rock crust guideline. correlation matrix heatmap revealed highly positive Cr (R2 = 0.66), these elements same source are likely prevalent soils. spatial origin publications reveals 82% studies followed by South Africa Italy accounting 4% respectively Nigeria, Egypt, Morocco, Iran, Turkey account 2% each. findings study important implications environmental regulation protection Unlike previous often adopt "silos" method, highlights nexus approach integrates both experimental could establish more understanding

Human Health Risk Assessment of Potentially Toxic Elements in Soil and Rice Grains (Oryza Sativa) Using a Combination of Probabilistic Indices and Carcinogenic Risk Modelling

Опубликована: Янв. 1, 2025

Agricultural soils and crops are increasingly vulnerable to contamination by potentially toxic elements (PTEs), exacerbated anthropogenic activities. This study aimed evaluate the human health risks associated with PTEs (Cd, Cr, Hg, Cu, As, Zn, Ni) in agricultural soil rice grains from different cultivated paddy Northern Cameroon. In this research, a modified Susceptible-Infected-Removed-Susceptible (SIRS) model, based on mathematical derivatives, was employed alongside carcinogenic non-carcinogenic risk assessment method through various indices. A total of 100 samples including (Oryza sativa) were analysed using inductively coupled plasma–mass spectrometry (ICP-MS) (Perkin Elmer Nixon 300Q). The mean concentration Cr (43.56 mg/kg) Vele, as well (43.48 Ni (36.24 Zoulla, exceeded geochemical background values. concentrations Cd, Ni, Zn within limits set WHO/FAO, except for Djogoidi, which WHO/FAO recommended value 0.1 mg/kg. Additionally, content Droumka twice high value. Similarly, bioaccumulation factor (BAF) (3.53 mg/kg), Cu (3.25 (2. 59 Djogoidi Cd (4.44 (3.22 (2.44 one two-fold higher than 1 denoting potential bioaccumulates metals grains. Also, (CRFS) indicates Hi (4.49E+02) children exceeding critical (threshold = 1) carcinogenicity standards, indicating very risk. results dynamic model also confirm susceptibility mortality over time due ingestion contaminated crops. is particularly evident following PTEs: show an increasing trend I_h (t), increase, α 0.25. Therefore, targeted mitigation measures necessary be adopted food protection pollution area.
