Read more...This study investigated mercury contamination with respect to the sediment characteristics in Gumu Creek near the Pohang Industrial Complex, South Korea. The contaminated sediment had high levels of Hg, exceeding 250 mg Hg/kg sediment at the sampling position, and high concentrations of iron, sulfur …

Total Hg content in the sediment was found to gradually increase (by approximately two times) towards the surface in both the cores. It was found that Hg was preferentially bound to sulfide under anoxic condition. However, redox …

Sediment mercury can be converted by microorganisms into methylmercury, a highly toxic chemical that builds up in fish, shellfish and animals that eat fish. At high levels of methylmercury exposure, harmful effects on these animals can include reduced reproduction, …

At high levels of methylmercury exposure, harmful effects on these animals can include reduced reproduction, slower growth and development, abnormal behavior, and even death.
