Introduction: Mercury, being widespread in environment, has toxic effect on a human organism even at a low concentration. Therefore, quantitative determination of mercury in various environments is one of the most important environmental monitoring problems. The use of a mercury analyzer RA-915M/Light-915M2 with Zeeman background correction provides direct real-time continuous determination of mercury in air from 0.5 ng/m3 within the overall possible range of mercury concentration in ambient ...

Introduction 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". ...

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 ...

Introduction : Analysis of soils, bottom and overburden sediments, rocks and ores for mercury content is one of the most common measurements in environmental pollution monitoring and geochemical exploration. Lumex Instruments proposes a rapid and precise method for direct mercury determination using RA-915 series analyzers based on atomic absorption spectroscopy with Zeeman correction of the background absorption (ZAAS). The thermoscanning option ...

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 ...

Introduction Mercury 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 ...

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 ...
