Title
In-Situ Mercury Stabilization
Summary Describes an in-situ process of mercury
stabilization (ISMS) with an option for removal from waste.
Mercury is first concentrated by inserting rods of sulfur reagent into
the waste. The mercury in the waste migrates to the rods and
reacts with the sulfur reagent to form a stabilized mercury sulfide
compound. The stable and insoluble mercury sulfide compound can
then be removed.
Competitive Advantage The described in-situ
soil remediation process allows the removal of mercury without
excavation and replacement of large volumes of the waste material
thereby reducing cost and environment impact.
Applications Industries and consulting firms
involved in mercury cleanup will find immediate use of the ISMS
process.

Title
Measurement of Aerosol Bulk Chemical Compositions
Summary Describes an apparatus that can
be used to analyze the chemical composition of ambient aerosol
particles.
Competitive Advantage The instrument can rapidly
measure the chemical components of ambient aerosols. This
rapid measurement circumvents drawbacks such as thereby aerosol
losses, greater complexity due to the need for sample

designed for automated bulk composition measurements.
Applications The method can be used to build
air quality monitoring devices to understand the sources,
atmospheric transformation, fate and health effects of ambient
aerosols.
