| Rezumat≠ | Environmental Impact Assessment (EIA) is a systematic, structured process to identify, predict, and evaluate the environmental and social consequences of proposed development projects (infrastructure, extraction, manufacturing) before implementation. Mandated by law in most jurisdictions since the 1970s (NEPA in USA, EU Directive 2011/92/EU), EIA integrates scientific analysis of air quality, water resources, biodiversity, noise, and socioeconomic effects with stakeholder consultation and decision-making frameworks to inform project approval, design modification, or rejection. | Heavy metal speciation is the analytical and geochemical determination of the chemical forms (species) and partitioning of toxic metals (lead, cadmium, chromium, zinc, copper) in soil, sediment, and water. Metal bioavailability—the fraction accessible to organisms—depends critically on speciation: metal bound to soil organic matter or iron oxides is immobile and non-bioavailable; dissolved or exchangeable metal is highly bioavailable and toxic. Speciation assessment informs remediation design, risk assessment, and contaminant fate prediction. |
