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 ...

Health and environmental training in mercury-contaminated areas
In 50 countries small-scale miners recover gold by amalgamation process, using excessive quantities of mercury. Fifteen million artisanal gold miners apply this process and 100 million people might depend upon these activities. Small-scale mining adds extensively to the worldwide release of mercury into the environment. The University of Munich assessed the health of people living in mining ...

Lumex Instruments takes part in making Mercury history
Minamata disease is one of the most notorious ecological catastrophes of the 20th century. Discharge of mercury-containing effluent by the "Chisso" chemical plant to the Minamata Bay in Kumamoto Prefecture, Japan, gave rise to a dangerous syndrome that seriously affects the central nervous system due to the toxicity of methylmercury, which gets into the body with contaminated food. In our blog, ...

Mercury and the problems of its disposal
With the increase in the scale of production in XX century has become a problem of creating disposal and storage of waste, in particular mercury, which is hazardous toxicant. Recently mercury has been used for industrial purposes very widely. At the same time, there was lack of proper ideas about the correct handling of waste, so the environment was exposed to pollution nearly uncontrollably and ...

Surfactant enhanced in-situ remediation of DNAPL impacted soil and groundwater - Montreal refinery
Abstract A Montreal chemical refinery reduced the dichlorobenzene and other dense non-aqueous phase liquid (DNAPL) impacts on the soil and groundwater where a railway line is adjacent to an above ground storage tank farm. Ivey-sol® surfactant mixtures were injected three times during a two week pilot test, into a series of in-situ wells. The soil and groundwater matrix experienced an induced ...

Continuous measurement of mercury emissions in combustion plants (Overview and new measuring method)
Introduction Continuous measuring devices have been used for continuous recording of Hg emissions in waste incineration plants since the early Nineties. Operators of combustion plants must maintain a 24-hour measured value of 30 μg/m³ mercury and a half-hourly average value of 50 μg/m³ in accordance with the 13th and 17th BImschV. In order to meet these requirements, measuring ...
