PEMU — An Impact Model Based Environment Protection Decision Support System

PEMU is being developed as a user friendly decision support system for environmental conservation an a national level. It supplies connections between pollutant emission of point sources, immission (conc./depos.) at receptor points or grid elements and environmental consequences. The user is provided with a tool for evaluation emission reduction strategies by scenario technique and by optimization facilities in order to calculate optimal timing of control strategies and minimal needed immission reduction to meet future goal states of environmental systems. Presently, PEMU is based on S02 and pine stand decline. Inclusions of dust, nitrogenium species, summer/winter immission and spruce stand impacts are being prepared.
