PRTR results can be used as inputs for dispersion models
PRTR results provide local, regional, national and international information. With a PRTR system in place, local or regional governments can assess the status of local emdronments and can use PRTR results as one input for assessing risks to human health and the emdronment. The use of PRTR data as a key input for assessing such risks enables national authorities or international groups to estimate and compare emdronmental problems on a consistent and common basis, e.g. by considering multiple pathways to exposure and movement through the emdronment of the pollutants covered by the PRTR. In other words, PRTR results can be used as inputs for dispersion models in order to obtain estimates of emdronmental status as a function of time and place.
