## Abstract The Washburn theory is frequently applied to determine the wetting angle of soils. It is based on the porous medium being characterized as a set of cylindrical, straight capillaries. It is clear that this is an oversimplification as real soil pores vary at least as regards two important

The potential of solid phase microextraction (SPME) for the determination of the soil fumigants 1,3-dichloropropene (1,3-DCP) and methyl isothiocyanate (MITC) in environmental samples such as soil and water samples has been investigated. Direct immersion SPME followed by GC/ECD/NPD analysis allowed

A novel colorimetric-based field test kit, the Quick Testா, has been developed by Envirol Inc. (North Logan, UT), for the quantitation of pentachlorophenol (PCP) in soil. The Quick Test differs from commercially available immunoassay field tests for PCP in that it is based on a photochemically induc
