The US EPA’s method 30B is designed as a reference method for determination of mercury emissions with stack gases. The method uses sorbent traps to capture total mercury from stack gas. Use of different sorbent traps also enables mercury speciation measurement. Method 30B is widely used for regulatory CEMM verification and for national and international research programs. This technology was also adopted for PRC (HJ 917-2017) and EC (TS ...

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 ...
