PLANTS, PEOPLE, PLANET, EarlyView.Lead (Pb) accumulation in the human body poses serious health risks. As rice is the staple food in Sri Lanka, with a high per capita intake (114 kg), there is a significant risk of Pb transfer through rice consumption. This study evaluated exchangeable Pb concentrations in soils and produced Pb distribution maps.

Rare Metals, EarlyView.ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.
