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.

Article Abstract:
Research was done by the Danish Forest and Landscape Research Institute and the Technical University of Denmark comparing the reliability of soil water samplers made of ceramic with that of poly(tetrafluoroethene) samplers. Unlike previous short-term laboratory studies, this study compared the samplers over a long period of time under field conditions. The study examined the concentrations of several base cations and nonpurgeable organic carbon in both types of 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.
