An algebraic/graphical tool to compare ecosystems with respect to their pollution. IV: Comparative regional analysis by boolean arithmetics.
Chemosphere 38, 2263-2279 (1999)
To perform an evaluation of landscapes, regions, etc. protection aims are to be defined. One possibility is to characterize geographical regions by their pollution with chemicals. Taking into account that the ecological effects may be different for each of these chemicals, an aggregation to one evaluation index does not make sense. An alternative is the concept of partial order, which is outlined here. A transformation is shown, by which easily understandable Hasse diagrams are obtained. The main conclusion is that five out of 59 regions in Baden-Wuerttemberg are (of high) priority, however for different reasons. Furthermore, the analysis by partial order shows that a high Zn pollution is only combined with an accumulation of Cd. Former mining activities may be the reason for that. Finally it is shown, how on a qualitative basis some general information can be put into the evaluation technique (Hasse diagram technique) described in this paper.
