Accelerated solvent extraction: an evaluation for screening of soils for selected U.S. EPA semivolatile organic priority pollutants

Article Abstract:

The Accelerated solvent extraction method, developed by researchers of the Environmental Protection Authority of Victoria, Australia, proved to be a cost-effective and superior method for screening soils for the presence of semivolatile organic priority pollutants. The newly developed method relies on high temperature and pressure to rapidly extract small amounts of conventional organic solvents which contain the pollutants. The Accelerated solvent extraction method was found to be better than the Soxhtet and bath sonication/shaking extraction methods.

Sampling artifacts in the determination of particulate sulfate and SO2(g) in the desert Southwest using filter pack samplers

Article Abstract:

The effectiveness of the filter pack sampling system in determining particulate sulfate and SO2(g) in desert soil samples is investigated. The results showed that SO2(g) can be collected by desert fine particles during the sampling process, thus giving measured concentrations which are inaccurate and are higher than actual levels. It is shown that filter pack sulfate sampling artifact magnitude is not associated with atmospheric particulate concentrations.
