Effect of FeS on mercury behavior in mercury-contaminated ...

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 …

Mercury profiles in sediment from the marginal high of ...

22-01-2016· 22-01-2016· Total Hg distributions and its speciation were determined in two sediment cores collected from the western continental marginal high of India. 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 …

Indicators: Sediment Mercury | National Aquatic Resource ...

27-11-2013· Mercury is a common pollutant of aquatic ecosystems and it can have a substantial impact on both human and wildlife health. 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, …

16-08-2016· 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, slower growth and development, abnormal behavior, and even death.
