From water and sediment to seafood: Heavy metal contamination and human health risk in wild and cultured oysters from a developing coastal region.

Summary: Imagine eating fresh oysters from the coast, only to find out they might be hiding harmful metals! Scientists looked at wild and farmed oysters, water, and mud from the coast of Bangladesh. They found that the mud was mostly clean, but the oysters soaked up a lot of metals like zinc and iron. Farmed oysters had even higher levels of lead and mercury. The biggest worry for people eating these oysters is arsenic, which can increase the risk of cancer. While the ocean environment seems okay for now, eating these oysters could be risky for human health.
