    Notes: Abstract Decision–support systems in the field of integrated water management could benefit considerably from social science knowledge, as many environmental changes are human-induced. Unfortunately the adequate incorporation of qualitative social science concepts in a quantitative modeling framework is not straightforward. The applicability of fuzzy set theory and fuzzy cognitive maps for the integration of qualitative scenarios in a decision–support system was examined for the urbanization of the coastal city of Ujung Pandang, Indonesia. The results indicate that both techniques are useful tools for the design of integrated models based on a combination of concepts from the natural and social sciences.

    Treatment of Young Spruce Shoots with SO2 and H2S: Effects on Fine Root Chromosomes in Relation to Changes in the Thiol Content and Redox State (1999)

    Notes: Abstract Three year old spruce trees (Picea omorika) were exposed to 100 and 225 nl l-1 SO2 and H2S for three weeks. The number of chromosomal aberrations and the mitotic index in the root tip meristems, and glutathione and cysteine contents in fine roots were determined twice weekly. An increase in glutathione content in fine roots of H2S exposed plants was only detectable after 13 days of fumigation. The number of chromosomal aberrations increased significantly after 9 days of exposure to 225 nl l-1 H2S and after 13 days of exposure to 225 nl l-1 SO2 or 100 nl l-1 H2S. This increase in chromosomal damage persisted up to the end of the 3 week treatment. Neither SO2 nor H2S exposure affected the cysteine content or the redox state of glutathione in fine roots. These results suggest that the development of chromosomal aberrations during SO2 and H2S exposures does not directly reflect changes in thiol/glutathione content or redox state in the fine roots.
