Article Synopsis
- Trace elements contaminate wild fish in megacities like Chongqing, posing health risks that require careful consumption practices.
- A study from June 2021 found high levels of zinc (Zn), lead (Pb), chromium (Cr), and arsenic (As) in certain fish, with smaller fish typically being safer for adult consumption compared to those targeted at children.
- The research highlighted that larger fish are generally more contaminated, particularly with arsenic, and suggested that choosing appropriately sized fish can help minimize health risks associated with trace element consumption.
The sources and health risk variation of heavy metals (HMs) in sediments of Liujiang River Basin were investigated seasonally to clear the control of HMs contamination in karst rivers. The results revealed the exogenous input of HMs should be more prominent in wet season, due to the higher concentration and EF values. PMF identified HMs were mainly from natural, mining and industrial sources.
