Most of the industrial plants in Moscow are located in the eastern, southeastern, and southern districts, where artesian water has been polluted the most (Figure 4 : Ecological impact on municipal districts in Moscow, 1992). These are also the districts with the greatest risk of radioactive contamination, and necrosis of vegetation, since 1982. The northwestern district, however, is located near one of the most traditionally prestigious areas in Moscow, which was a high income, high status neighborhood even before 1992. The central district of Moscow, adjacent to the northwestern district, was also the shopping nexus, attracting many transients, foreign tourists, and migrants from other parts of the Russian Federation. On the other hand, the central district adjacent to the southeastern district, had the worst ecological quality of life.
