Heavy metals in Yellow River sediment pose indirect hazard, accumulating pollution.

The study looked at heavy metal pollution in sediment from the Yellow River Estuary and nearby sea areas. They found that copper, lead, zinc, and cadmium levels were low and similar. Mercury and arsenic were the most polluted metals, with mercury slightly lower than arsenic. Over half of the sampling sites had heavy metal levels above safe levels, indicating moderate pollution. This suggests that the Yellow River Estuary's heavy metal pollution poses a potential ecological risk.
