  • 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 ...

  • 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 ...


  • Mercury Ban – Printers Unaffected

    The mercury ban debate has been rife with speculation, confusion, strong accusations and well, a little bit of misleading information. So, together with Brendan Perring of Print Monthly I have been getting to the bottom of this tangled web of information. We have been in contact with the National Measurement and Regulations Office (NMRO) to seek clarification, and today I found myself meeting a ...

  • Agreement on mercury finally here

    In Geneva 19 January 2013, due to successful interaction between science and policy making, governments within the UN agreed to a global, legally-binding treaty to prevent emissions and releases of mercury. Prof. Jozef Pacyna and his team at NILU - Norwegian Institute for Air Research, have played a major role in providing the UN policy makers with scientific justification for the treaty. 30 year ...

  • Mercury Spill Control Procedures

    Mercury is a known neurotoxin that is extremely toxic even in small amounts. It directly affects the central nervous and renal systems, causing developmental delays, motor and brain problems like those associated with autism. Mercury"s hidden danger also lies in when at room temperature, when exposed it vaporizes readily. Once ...


  • The source and risks of mercury in the offshore industry

    Oil in Gas and RocksAlmost all oil and gas is found within the tiny spaces in sedimentary rocks, mainly sandstone and coarse-grained limestone. Bedrock limestone and sandstone, even though hard, also contain lots of pores that can contain water or oil or gas and other elements. Along with the gas and oil is a mixture of sand, silt & mud. This sludgy silt mud is rich in heavier metal elements ...

  • Tekran instruments—monitoring around the world

    Tekran provides trace-level mercury analytical and monitoring technology for a variety of applications including laboratory-based sample analysis, continuous point-source emissions and ambient air monitoring. This article focuses on and highlights the results of an application of Tekran’s Ambient Air Mercury Speciation System. In contrast to most other heavy metals, mercury (Hg) and mercury ...

  • Increase Mercury Vapor Detection Range by 10X

    Vapor dilution module extends detection range of J505 from nanograms to milligrams How it works: The new 10:1 dilution module for the J505 reduces the concentration of mercury vapor in the sample stream by a factor of ten, allowing for a much higher detection limit. Rather than the standard upper detection limit of 500 µg/m3, ...

  • Overview of mercury control in coal-fired power plants

    During combustion, the mercury (Hg) in coal is volatilized and converted to elemental mercury (Hg0) vapor in the high temperature regions of coal-fired boilers. As the flue gas is cooled, a series of complex reactions begin to convert Hg0 to ionic mercury (Hg2+) compounds and/or Hg compounds (Hgp) that are in a solid-phase at flue gas cleaning temperatures or Hg that is adsorbed onto the surface ...

  • Continuous Mercury Monitoring Benefits Cement Plants

    Antti Heikkilä from Gasmet Technologies highlights the challenges faced by mercury monitoring in cement kilns, and explains how a new continuous mercury monitoring system addresses these issues and provides process operators with an opportunity to improve environmental performance and demonstrate compliance with forthcoming legislation. Background The production of cement ...

  • The determination of mercury at ultratrace levels using FIMS and amalgamation technique

    The PerkinElmer Flow Injection Mercury System (FIMS) is used in combination with an amalgama¬tion preconcentration technique to determine Hg at ultratrace concentrations. Using a 10-mL sample volume, the instrumental detection limit is 0.3 ng/L. The method detection limit obtained in drinking water is 1.0 ng/L with a spike recovery of 100 ± 4%. The operating conditions for the ...

  • 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 ...

  • Remediation of mercury contaminated industrial site for future expansion - case study

    70,000 tons of mercury contaminated soil and building rubble have to be cleaned in an industrial facility in the south of France until 2013. For the realization of this remediation work, an econ industries VacuDry® 12,000 has been in operation since early 2011. After the treatment the mercury free soils can be re-used on-site as building material. A similar but smaller econ industries ...

  • Tech update: Plant instrumentation - food engineering

    Sensors and other devices are the foot soldiers in automation architecture, but most food and beverage manufacturers still are looking for full value. You know an equipment category has arrived when it starts getting its own industry-specific center. For the food production sensors that do the heavy lifting in instrumentation technology, that day could arrive earlier rather than ...

  • Analysis of Mercury in Wastewater by Microwave Digestion Followed by ICP/MS: Comparison to EPA Methods Approved at 40 CFR 136.3

     ABSTRACT As a cost-saving measure, the use of an existing microwave digestion system and ICP/MS instrument was investigated for the analysis of mercury in domestic wastewater, industry effluent, storm water, and other aqueous matrices analyzed under the City of Portland’s various NPDES permits. A formal alternate test procedure application (ATP) study was undertaken to add total ...

  • Integrated product policy: a case study of batteries

    The increasing complexity of product chains is an argument for analysing actors and policy instruments throughout the lifecycle of products. Actors are persons or corporations deciding upon the fate of the product. The policy instruments refer to well-known measures like information, economic or administrative measures. The theoretical part of the study discuss governance and the role of policy ...
