Metal(loid) contamination caused by industrial activities in agricultural soils has become a universal environmental and food safety concern. This study revealed the contamination, pathway, and source contribution of metal(loid)s such as lead (Pb), zinc (Zn) and cadmium (Cd) in maize and soils in different residential areas impacted by long-term historical artisanal zinc smelting activities from Southwest China. Results revealed that the soils were contaminated heavily by metals like Pb, Zn and Cd, with contents of 40-14,280, 150-47,020 and 1.

- Thallium (Tl) is a toxic trace metal causing global pollution in water, but there are few effective methods to remove it from wastewater.
- A novel adsorbent made from a MnFeO-biochar composite (MFBC) has been developed, showing a high removal capacity of 170.55 mg/g for Tl(I) at an optimal pH of 6.0.
- The MFBC demonstrates various removal mechanisms (adsorption, ion exchange, etc.) and is noted for being environmentally friendly, cost-effective, and efficient with notable magnetic properties and a large surface area.
