Working on a hazardous materials team means being prepared for the unexpected, from toxic chemicals to unidentified powders to overturned trucks. Should “the unexpected” ever include mercury and mercury vapor contamination incident response, trust Jerome mercury vapor analyzers to keep your team and your community safe.
Waste incinerators, cement plants and power plants need good and reliable measurements of total gaseous mercury. The measurement of total gaseous mercury is a challenge due to chemical reactions and contamination. The installed systems will often require a lot of maintanence still not giving reliable results.
Robust analysis for inspection, investigation, remediation. If you are responsible for monitoring a wide range of environments for mercury contamination, it’s not enough that your instrument is accurate. It must also be responsive, reliable, and rugged. Jerome has the answer.
Measurement of mercury content in hair is a convenient technique to estimate dietary exposure without having to handle tissues or bodily fluids. As the mercury present in hair is comprised of different mercury species, full speciation of the compounds is needed for complete understanding. Environment Canada published a technique where treating a basic digestion with Cd2+ in the presence of cysteine allowed analysis of inorganic mercury and total mercury using a Tekran 2600 System. Methyl mercury was then calculated...
Keeping people safe is your calling. But when dealing with a slow-acting neurotoxin like mercury, it can be hard to tell when an environment may be hazardous. In these uncertain situations, trust Jerome®, the most respected name in mercury vapor analysis for nearly 40 years. Our rugged and reliable instruments are designed and built in the USA, so you can be confident that the Jerome will be there when you need it.
Analysis of soils and bottom sediments for mercury content is one of the most common analyses in the monitoring of environmental pollution. Background mercury concentrations in these objects are 10–100 μg/kg and in the polluted areas they exceed 10,000 μg/kg.
Mercury is widely used in chemical industry, electronic s, electric engineering, instrument making, medicine, pesticide and explosives production, etc. A number of techniques and equipment are developed for reclaiming mercury-containing waste, such as soil, sludge, stillage botto ms, slime sediments, fluorescent lamps, mercury-containing batteries.
IntroductionMercury is one of the most toxic trace contaminant naturally occurring in the coals. During the coal combustion process at the coal-fired power plants mercury is released into the environment. To manage effectively the stack gas cleaning process, it is necessary to know the mercury content in the coal, and also in stack gas, liquid and solid wastes.
High mercury concentration can be found in such cosmetic products as skin lightening soaps and creams, makeup cleansing products, and mascara.
Mercury in cosmetics exists as inorganic and organic compounds. Inorganic mercury (e.g. ammoniated mercury) is used in skin lightening soaps and creams. Organic mercury compounds, such as thiomersal, are used as cosmetic preservatives in makeup cleansing products and mascara.
Mercury and its compounds are highly toxic substances fo r humans. It occurs naturally and exists in various forms: elemental (or metallic); inorganic (e.g. mercuric chloride); and organic (e.g., methyl- and ethylmercury). These forms all have different toxicities and implications for health. Among naturally occurring mercury compounds, methylme rcury exerts a significant influence (neurotoxic action) on human health.
The mercury concentration in crude oil and petroleum products can vary in a wide range of less than 0.1 ppb to dozens ppm. Direct mercury determination in crude oil and petroleum products at the range above 5 ppb is covered by ASTM D7622-10(2015) "Standard test method for total mercury in crude oil using combustion and direct cold vapor atomic absorption method with Zeeman background correction". Mercury determination in naphtha and light petroleum products (condensate, gasoline and diesel fuel) at a...
Mercury, being widespread in environment, has toxic effect on a human organism even at a low concentration. Therefore, quantitativ e determination of mercury in vari ous environments is one of the most important environmental monitoring problems. The use of a mercury analyzer RA-915M/RA-915+/RA- 915Light with Zeeman background correction provides di rect real-time continuous determination of mercury in air from 0.5 ng/m 3 within the overall possible range of me rcury concentration in ambient air.
Besides Mass Spectrometry, a further variety of analysis techniques are categorized as atomic spectroscopy. Analysis techniques which use inductively coupled plasma (ICP), such as ICP-OES and ICP-MS, are among these. With increasing environmental awareness backed by regulations, an increasingly important use of atomic spectroscopy techniques is in mercury analysis. Achieving a high mass flow control performance, e.g. high repeatability or an excellent turn-down ratio, is a prerequisite to achieve a high analyzer...
Quantitative determination of the total mercury content in filtrates of wash-off samples from the surfaces of walls, floors, equipment, and other facilities of m anufacturing areas is an effective method for the occupational safety monitoring.
