  • 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 ...

  • Accumulation of mercury and cadmium in rice from paddy soil near a mercury mine

    Paddy soil and rice (Oryza sativa L.) in the Wanshan mining area in Guizhou province have been contaminated by toxic trace metals such as cadmium (Cd) and mercury (Hg). This study examined correlations between the types and physico‐chemical parameters of the soil and the contents of trace metals and the different forms of Hg in rice. The study also carried out an assessment of the health risks ...

  • 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 ...

  • Evaluation of two in vitro protocols for determination of mercury bioaccessibility: influence of mercury fractionation and soil properties

    Received for publication November 10, 2008. Soil ingestion by children can be a significant exposure pathway to mercury (Hg). Unfortunately, no reliable in vivo results for Hg oral bioavailability determination in soils have been published. In vitro extractions enable the assessment of metals' bioaccessibility, which is an estimate of oral bioavailability. Therefore, the goal of this study was to ...

  • Distribution of mercury in the water and bottom sediment of the J.A. Alzate Dam, Mexico

    In this paper, mercury concentration in the soluble, particulate and total fractions of water and in the sediment from the Jose Antonio Alzate Dam in the State of Mexico was evaluated using neutron activation analysis in order to determine the bioavailability and distribution of this metal. Sampling was carried out on three separate seasons – cold dry season, hot dry season and rainy season – ...

  • Mercury mobility and availability in highly contaminated solid wastes from a chlor-alkali plant

    This article suggests an approach of sustainable development in Cuba based on the environmental impact assessment of mercurial sludge generated by a chlor-alkali Cuban plant. It consists of a study of mercury mobility and availability in the sludge samples using sequential extraction procedure. High values of total mercury content (2320 ± 40 mg/kg) in the sludge sample as well as in the ...

  • Heavy metal removal - Case Study

    KDF 55 and 85 Provide Non-Chemical Water Treatment Media for Lead Removal and Other Heavy Metal Removal from Water In New Jersey's mercury contaminated groundwater - KDF media have been removing mercury to levels below the MCL since 1992. Redox media, non-chemical water treatment remove up to 98% of water-soluble cations (positively-charged ions) of lead, mercury, copper, nickel, chromium, and ...

  • Hazardous waste characterisation of high-density discharge lamps

    This study was conducted to assess the relative hazards of used high intensity discharge lamps, based on metal analysis. The paper indicates the inherent difficulties associated with the samples and describes how this particular type of waste might be analysed. The lamps were analysed for total and soluble metals, including mercury, in order to determine inorganic persistent and bio-accumulative ...

  • Minimization of Major Air Pollutants from Sewage Sludge Fluid Bed Incinerators

    ABSTRACT Emissions of major air pollutants including carbon monoxide (CO), nitrogen oxides (NOx) and mercury (Hg) were studied at two sewage sludge fluidized bed combustion (FBC) plants. Both the North West Bergen (NWB) County Utility Authority and the Little Miami (LM) plants have air pollution control systems (APCS) that are of the wet type. Various operating conditions such as temperature, ...

  • 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 ...

  • In-Situ Remediation of Heavy Metals Using Sulfur-Based Treatment Technologies

    The Metal Problem Highly toxic and highly soluble metals are contained in numerous waste streams including those from power, chemical, electronics facilities, general manufacturing plants, and mining facilities. Lead, chromium, arsenic, zinc, cadmium, copper, and mercury are the most common metal contaminants found on remediation project sites (US EPA, October, 2000). Cyanide is a common ...

  • Multiple stage scrubbing and adsorption system for Incinerator exhaust at an industrial waste processing plant

    Challenge Monroe Environmental was called upon to purify a 20,000 CFM exhaust stream that was being discharged from an industrial waste incinerator at 2000° F. The pollutants that needed to be removed were: Fine Ash Particulate HCL Gas Mercury Dioxins The combination of soluble and solid pollutants, coupled with the ...

  • Arsenic Removal

    The Arsenic Removal ProcessArsenic, a naturally occurring element, is found throughout the environment; for most people, food is the major source of exposure. Acute (short-term) high-level inhalation exposure to arsenic dust or fumes has resulted in gastrointestinal effects (nausea, diarrhea, abdominal pain); central and peripheral nervous system disorders have occurred in workers acutely ...


  • Properties and Behavior of Inorganics in Contaminated Soil

    Often, specific technologies may be ruled out, or the list of potential technologies may be immediately narrowed, on the basis of the presence or absence of one or more of the chemical groups. The relative amounts of each may tend to favor certain technologies. Metals may be found in the elemental form, but more often they are found as salts mixed in the soil. At the present time, treatment ...

  • Ex Situ Biological Treatment for Groundwater, Surface Water, and Leachate

    The main advantage of ex situ treatment is that it generally requires shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to monitor and continuously mix the groundwater. However, ex situ treatment requires pumping of groundwater, leading to increased costs and engineering for equipment, possible permitting, and material handling. ...
