Transformations of elemental mercury to inorganic and organic forms in mercury and hydrocarbon co-contaminated soils

摘要: There are many industrial sites, such as gas processing plants, that contaminated with both mercury and hydrocarbons. These sites tend to be localized but can have very high concentrations of in the soil heterogeneous distribution The original form cases was elemental from broken manometers. Over time has become redistributed within undergone chemical transformations into new forms. forms will govern behavior availability biological receptors. is important it risk associated also determine effectiveness any attempts at remediation. In present study a extraction protocol used originally by spillage petroleum Chemical extractions been past uncontaminated soils several researchers them soils. However, date, no studied following years weathering after spill. This shows decades spill transformed dominantly (up 85%) organic matter, lesser extent mineral fraction soil.
