    Mercury determination in natural, surface, sea, drinking, bottled, mineral, and waste water by cvaas

    Introduction Mercury determination in natural, drinking, and waste waters is one of the most popular analyses used for environment pollution and sanitary control. Background concentrations of mercury in natural water are within several ng/l. Maximum national permissible levels for mercury in water lie in the range of 0.16–6 µg/l. For example, the following limits for mercury in drinking water are set, µg/l: 0.5 – Japan, Russia; 1 – Argentina, Australia, Brazil, China, EC; 2...

    Monitoring of mercury in ambient air

    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.

    Mercury determination in natural gas

    Introduction The natural gas is a significant source of ingres s of mercury in the environment. The typical mercury concentration in natural gas may vary from 0.01 to 200 μ g/m3 . Mercury, being present in hydrocarbon gas, initiates corrosion of pipelines and catalyst poiso ning during gas transportation and processing, and these effects have serious implications for the gas-processing industry.

    Determination of total mercury content in blood by cvaas

    INTRODUCTION Blood is one of the most complex substances for determination of the Hg content. At the same time, blood is the most important diagnostic medium used for monitoring the effect of Hg vapor on the human organism. In almost all the countries, personnel of mercury-involving production facilities are regularly examined for the Hg content in blood, which should not exceed 20–50 µg/l, whereas in the case of a person unexposed to mercury vapor the blood normally contains 1–3 µg/l of Hg.

    RAPID ANALYSIS OF TOTAL MERCURY IN WASTE WATERS AND PROCESS WATERS WITH ELEVATED MERCURY CONTENT USING DIRECT PYROLYSIS TECHNIQUE

    A conventional standard method of total mercury determination in water using atomic absorption spectrometry (AAS) involves preliminary sample digestion that takes from 30 minutes to 8 hours depending on the digestion conditions. The use of a mercury analyzer RA-915M/RA-915+ with Zeeman background correction in combination with PYRO-915+ pyrolysis attachment provides direct determination of mercury in process and waste waters contaminated with mercury without digestion or any other sample preparation stages.

    Direct mercury determination in coal

    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.

    Direct AA Mercury determination in cosmetics

    INTRODUCTION 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.

    Direct atomic absorption mercury determination in tissues and biological samples

    INTRODUCTION 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.

    Mercury monitoring for measuring mercury content in hair

    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...
