A sequential extraction procedure has been applied to study the speciation of Chernobyl-derived radionuclides (137Cs and 90Sr) in soils from Norway, and from Byelorussia and the Chernobyl region in the USSR. Most 137Cs (greater than 80%) was strongly associated with soil components, whereas 90Sr was more mobile, up to 70% being found in the easily(More)
C2H2F4-oleoresins of black pepper (dried fruits) and ginger (dried roots) from Vietnam were tested for their antimicrobial activities against some different strains of yeast, Gram-(+)and Gram-(-)-bacteria by agar diffusion and agar dilution method, respectively. Both oleoresins showed a significant high antimicrobial activity against the Gram-(+)-bacteria(More)
Natural and artificial radionuclides are transferred from terrestrial ecosystems via the forest industry to coastal sea water. The material processed, i.e., wood, fresh water, and bark, have low levels of radionuclides, but large amounts of raw materials are processed annually. Thus the annual flux of radionuclides is substantial. The purpose of this(More)
