Resumen
The problem of propagation of pollutants emitted into the atmosphere by various industrial sources is formulated using the two-dimensional transport equation. An adjoint transport model and dual principle are derived that permit to impose sufficient restrictions on the emission rates of each industrial pollution source in order to maintain average pollution concentration in an ecologically important zone below a maximally admissible value. Two strategies of control of the emission rates are suggested. The first one is based on the minimization of the L2-norm of the emission rates subjected to a linking equation determined by the dual principle. The second strategy is derived from an adequate limitation on the temporal behavior of the emission rates. Both the strategies are defined in terms of the adjoint transpot problem solution.
