An anesthetized domestic swine model was used to compare the efficacy and cross-contamination potential of selected skin decontaminant products and regimens against the chemical warfare agent, VX. Animals topically exposed to 2x, 3x or 5x LD(50) VX showed typical signs of organophosphate nerve agent poisoning, including miosis, salivation, mastication,(More)
Below-ground carbon (C) production and nitrogen (N) flows in the root-zone of barley supplied with high or low amounts of N-fertilizer were investigated. Interest was focused on the effect of the level of N-fertilizer on the production of root-derived C and on gross immobilization (i) and gross mineralization (m) rates. The plants were grown for 46 days in(More)
Healthy young adult (300 g) Sprague-Dawley rats were exposed for 1-day or 5-day periods, nose only, to purified air (CA) or four different pollutant atmospheres. Pollutant atmospheres included (a) 0.2 ppm ozone; (b) 0.4 ppm O3; (c) a low concentration mixture of ozone and sulfuric acid-coated carbon particles (0.2 ppm, 100 microg/m(3) and 50 microg/m(3),(More)
The technique of crosswise labelling two otherwise identical laboratory incubation series was used in three different experiments to study immobilization and remineralization of mineral N in a sandy moraine loam soil. In experiments I and II the two series were cross-wise labelled with15NH4NO3 and NH4 15NO3 at the start of the experiment. In experiment I(More)
