Sediment pollution from potentially hazardous elements (PHE) generated by human activity has grown into a worldwide problem. In this regard, for the first time, surface sediment samples were obtained six points along Shahid Rajaee Reservoir investigation. Elements concentrations (Cu, Cr, Co, Mn, Fe, Pb, Ni, and Zn) assessed using ICP-MS. Based on individual indices (geoaccumulation index, contamination factor), all at sample sites found to be low in contamination, except Pb Zn (at 1 2). The combined effect of PHEs did not show considerable concern, according synergistic indices. health risk assessment revealed that recreational receptors unlikely face non-carcinogenic or carcinogenic hazards as consequence exposure sediments with unintentional ingesting contact skin. Tessier technique demonstrated mostly connected oxidizable fraction. According statistical study, while Cu, Mn lithogenic sources, came natural well human-made sources.

Multi-compartmental risk assessment of heavy metal contamination in soil, plants, and wastewater: A model from Industrial Gazipur, Bangladesh

Abstract Heavy metal contamination in industrial-agricultural regions poses global challenges, yet comprehensive risk assessment models addressing both ecological and human health impacts are scarce. This study introduces a novel multi-compartmental framework applied to the Saldha River region of Gazipur, Bangladesh, rapidly industrialising area experiencing significant environmental stress. Here, we analysed eight heavy metals (Cr, Pb, Cu, Fe, Mn, Zn, Ni, Cd) soil, wastewater, plant samples (spinach, wild rice, nut grass) via atomic absorption spectrophotometry (AAS). Ecological risks were evaluated through factor (CF), pollution load index (PLI), geo-accumulation (I geo ), while assessed using hazard indices (HI). Results revealed severe Cd (enrichment 2563.19), indicating substantial anthropogenic influence. Correlation analysis wastewater showed strong associations between pairs, such as Cu–Zn (0.92), Cu-Fe (0.90) Zn-Mn (0.87), common industrial sources. Transfer (TF) plants demonstrated variability uptake, with Mn Ni showing highest bioavailability, increasing local food chains. Human assessments indicated (HI) exceeding safety thresholds for adults children, underscoring urgent need mitigation strategies. offers novel, integrative assessing multi-source provides critical baseline data future policy development. The model is adaptable worldwide, textile hubs Southeast Asia or processing zones Europe North America, offering new insights into pathways management. Graphical
