NON-POINT DISCHARGES FROM URBAN AREAS 229Table—Sedimenting aerosols wash-off by NP discharge as a function of dust contentin the air.load down to the limiting level, a programme of NP treatment units must beconsidered. Design of such units can be based on the balance equation of fineparticles build-up and on found relationships (Khvat, 1988), allowing quantitativeevaluation of technogenic components (atmosphere pollution, road cover destruction,soil erosion, etc).Where urban territory is very heterogenerous it is necessary to solve an optimizationproblem, to choose between alternative ways of reducing technogenic polluting loads(minimization of environment-protection costs, giving a prescribed quality of NPdischarge in the water-use section).ReferencesKhvat V M (1983), Reglamentatziya vypuska poverkhnostnogo stoka stoka sgorodskoi territorii v vodnye objekty.
