Targeted Mercury Emissions from Power Plants
Electric Power is a driver of our nation's economy and critical
in maintaining our high quality of life. Coal-fired power plants,
however, have been targeted for additional emissions reductions including
sulfur dioxide, nitrogen oxides, and mercury.
Coal-fired power plants are targeted for mercury reductions to help reduce
the airborne levels of mercury that may eventually be deposited in water or
on land. Mercury concentrations in the air are low and of little direct concern.
However, once mercury enters water, biological processes transform it into
methyl mercury that bioaccumulates in fish and other animals that eat fish.
Human exposure to mercury occurs primarily through consumption of contaminated
fish.

Test Method
For sorbent trap mercury monitoring, known volumes of flue gas are extracted from a stack or duct through
paired spiked 3-section sorbent
traps at an appropriate flow rate. The sampling period can vary from
30 minutes to several days in duration. After sampling, the sorbent
can be acid leached and the resulting leachate is analyzed by cold
vapor atomic fluorescence spectrometry (CVAFS) or cold vapor atomic
absorption spectrometry (CVAAS). Other techniques for mercury analysis
that use no solvent extraction include direction combustion and thermal
decomposition with atomic absorption (AA) detection.
EPA Method 30B - For relative accuracy test audits (RATAs) of vapor
phase Hg CEMS and sorbent trap monitoring systems, known volumes
of flue gas are extracted from a stack or duct through paired spiked
2-section sorbent traps at an appropriate flow rate. A field recovery
test that assesses recovery of an elemental Hg spike to determine
measurement bias is also used to verify data acceptability. After
sampling, sorbent traps are prepared for analysis and analyzed by
any suitable determinative technique that can meet the performance
criteria such as those outlined in the above paragraph.
Independent of the application, sorbent traps must be obtained from
a reliable source such that high quality assurance and control ensure
consistent reliability. Persons sampling should have a thorough working
knowledge of other related sampling methods.

World Leader in Sorbent Sample Media Technology
30 years ago, SKC produced the first commercial sorbent traps. Since then,
SKC sorbent traps have been used by OSHA and NIOSH researchers and by federal,
state, and local government agencies for compliance and consulting. SKC sorbent
traps are known for their quality, consistent mesh size, low backgrounds, and
reliability. SKC uses its many years of experience in sample media technology
to bring you the high-quality, reliable vapor-spiked mercury emission testing
(MET) traps
you need to make your sampling job easy and accurate.
