Sustainable healthcare systems depend not only on hospitals and medical services but also on environmental safety, food security, and preventive public health strategies. Heavy metal contamination in agricultural inputs poses long-term risks to soil quality, water safety, food chains, and human health. This study evaluates the concentration of heavy metals in organic fertilizers collected from Uran Taluka, Raigad District (Navi Mumbai), Maharashtra using Sequential Extraction Procedure and ICP-AES analysis. The research integrates environmental science, public health, and regulatory perspectives to highlight how scientific research, educational awareness, and enterprise-level quality control can collectively strengthen sustainable healthcare systems.
