  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • The determination of total mercury in whole blood using thermal decomposition and amalgamation coupled with atomic absorption

    Mercury has long been recognized as a serious global pollutant that has a significant impact upon our ecosystem. Unlike most other pollutants, it is highly mobile, nonbiodegradable, and bio-accumulative and as a result has to be closely monitored to ensure its harmful effects on local populations are minimized. Approximately 50 tons of mercury particulates are emitted into the atmosphere every ...

  • Measuring total mercury due to small-scale gold mining activities to determine community vulnerability in Cihonje, Central Java, Indonesia

    This research is comparative study of gold mining and non-gold mining areas, using four community vulnerability indicators. Vulnerability indicators are exposure degree, contamination rate, chronic, and acute toxicity. Each indicator used different samples, such as wastewater from gold mining process, river water from Tajum river, human hair samples, and health questionnaire. This research ...

  • The possible toxic effects of lead

    Lead is a chemical element in the periodic table that has the symbol Pb (Latin: plumbum) and atomic number 82. A soft, heavy, toxic and malleable lead is bluish white when freshly cut but tarnishes to dull gray when exposed to air, very dense metal which is very soft, highly malleable, ductile, and a relatively poor conductor of electricity. It is odourless. It is highly resistant to corrosion ...

  • On the suitability of Portable X-Ray Fluorescence Analyzers for rapid screening of toxic

    Abstract X-Ray Fluorescence spectrometry (XRF) has been routinely used for alloy testing, determination of Pb in paint, and determination of Cd in plastic. However, its use to screen for toxic elements in food and medicinal products has been surprisingly limited to date. While XRF is less sensitive than atomic spectrometry methods such as ICP-AES and ICP-MS, it offers a number of significant ...

  • How to treat radioactive NORM sludge with VacuDry

    NORM doesn’t sound like a big thing. But Naturally Occurring Radioactive Material might let the alarm bells ring. Everyone has heard of “radioactive material” and that sounds dangerous. However, most of this material is trapped deep in the ground beneath our feet. From there it reaches the surface, for example via the water cycle. Another possible pathway for NORM to reach the ...
