Direct determination of mercury content in ambient air
Introduction: Mercury, being widespread in environment, has toxic effect on a human organism even at a low concentration. Therefore, quantitative e determination of mercury in various 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 direct real-time continuous determination of mercury in air from 0.5 ng/m 3 within the overall possible range of mercury concentration in ambient ...

Air pollution, emission and process monitoring systems for water & liquids
Mercury is one of the most toxic elements that may be found in natural water bodies and can negatively affect living organisms, human health as well as drinking water quality. In addition, water is the main transportation and transformation pathway of mercury into the environment and living organisms. Mercury analysis in water is of great importance, in order to monitor water quality and associated environmental stresses. Mercury is also known to be a persistent, bio-accumulative toxin, indicating that its ...

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 ...
