Key Scientific Findings for Lead

This scientific summary presents consolidated evidence on the hazards, environmental behaviour, sources, production, uses, exposure pathways and ecosystem impacts of lead. It describes how lead is transported through air, water and soil, identifies major anthropogenic and natural release sources, and outlines global trends in emissions and environmental concentrations. The document highlights the significant health risks, particularly for children, reviews impacts on ecosystems, discusses challenges faced by developing countries, and identifies priority data gaps requiring improved monitoring, assessment and scientific understanding.
