  • Mercury Spill Control Procedures

    Mercury is a dangerous neurotoxin that can have damaging affects on both the central nervous system and renal system of humans. Exposure to mercury can cause serious developmental delays in children, and high level exposure is life threatening. When exposed to air, mercury vaporizes, readily becoming a dangerous aerosol that can be absorbed into the lungs and spread throughout the body. This is ...


  • Removing mercury with activated carbon

    Granular Activated carbon is effective at physically adsorbing trace components from gas streams due to its high population of micropores; however, the capacity is low. By impregnating the granular activated carbon with a compound that will chemically react with the mercury, capacity can be enhanced. It is imperative that not only must the mercury be removed to non-detectable levels but that it ...

  • Increase in mercury in Pacific yellowfin tuna

    Mercury is a toxic trace metal that can accumulate to levels that threaten human and environmental health. Models and empirical data suggest that humans are responsible for a great deal of the mercury actively cycling in the environment at present. Thus, one might predict that the concentration of mercury in fish should have increased dramatically since the Industrial Revolution. Evidence in ...

  • Mercury Levels in Mink (Mustela vison) and River Otter (Lontra canadensis) from Northeastern North America

    Aquatic ecosystems have received mercury released from anthropogenic sources. The northeast region of North America is at especially high risk because of local and regional emission sources, prevailing wind patterns, and certain hydrological and biogeochemical features. Here we examine regional variation in total mercury (Hg) in brain, liver, and fur from otter and mink collected across New York, ...

  • High levels of maternally transferred mercury do not affect reproductive output or embryonic survival of northern water snakes (Nerodia sipedon)

    Maternal transfer is an important exposure pathway for contaminants because it can directly influence offspring development. Few studies have examined maternal transfer of contaminants, such as mercury (Hg), in snakes, despite their abundance and high trophic position in many ecosystems where Hg is prevalent. The objectives of the present study were to determine if Hg is maternally transferred ...

  • Determination of Ultra-Trace Mercury Vapor Levels from Industrial & Military Metal Components

    For many years, scrap metal reclaimers did not separate the materials containing mercury from other metals. Such things as mercury switches, dental amalgam, thermometers, and refining wastes from copper, gold and silver were processed along with the typical industrial metals. The result is that a significant portion of the Ferrous and non-Ferrous metals and alloys used today contain some metallic ...
