Source analysis and human health risk assessment of heavy metal in farmland soil-rice system in Nandu River Basin, Zhanjiang City, Guangdong Province, China

2025-11-03

Abstract excerpt

<title>Abstract</title> <p> This study aims to characterize heavy metal contamination in rice fields of the Nandu River Basin (subtropical red soil zone) and elucidate its risk mechanisms. Key objectives include assessing pollution levels/ecological risks, identifying contamination sources, and evaluating human health risks from soil-rice systems. Forty paired soil-rice samples were collected. Concentrations of...
