  • 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 soils and river sediments 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, non-biodegradable, 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 ...

  • Using FIMS to determine mercury content in sewage sludge, sediment and soil samples

    Tim Flow Injection Mercury System (FIMS) is a dedicated system that integrates flow injection mercury cold vapor generation with a very sensitive detector. The exceptional system stability and the long path measurement cell provide instrumental detection limits as low as 5 ng/L using a sample volume of 5(H) jxL. The improved sensitivity of the FIMS permits sample dilution, therefore reducing the ...

  • 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 ...

  • A Comparison Of Microbial Repair Mechanisms With Low Pressure And Medium Pressure UV Lamps

    Introduction It is well-known that bacteria and other microorganisms are capable of repairing their DNA following damage by ultraviolet (UV) radiation. Known as ‘reactivation’, it is a natural defense mechanism that has evolved over millions of years. Some microorganisms need visible light in order to repair their DNA (known as ‘photoreactivation’), while others can repair their DNA without light ...
