“…Even with air flow characterization, it cannot reliably determine specific source contributions in the measured deposition totaled from all sources. 1 With respect to the second option, one observes that tracers of opportunity are, at best, unique to broad classes of sources rather than a single source and are thus unlikely to yield unambiguous SRRs. Additionally, different physical and chemical properties of the tracers, and sulfur and nitrogen compounds of concern compromise any inferences that are drawn.…”

“…Experiment (Ex) 1 is conventional in that it determines the deposition (D) from all sources (0 by the sum, (1) where D w is the wet deposition component, and D^ is the dry deposition component. Actual SRRs are calculated in this case with the aid of a theoretical model to estimate £) w ,-or Ddi' -This approach does not go far enough in using the measurement base for SRRs and does not directly address any of the five key design questions stated above.…”

in conjunction with The MATEX Design Group A hypothetical field experiment is evaluated that relates, through tracer releases, reactive pollutant emissions to long range transport and deposition. The feasibility of such an approach is established provided certain requirements can be met. The experiment must: (a) trace emissions from several sources simultaneously and repetitively over an extended period of time, (b) link a tracer to the chemical behavior of emissions, and (c) apply a statistically sound method of guidance for deducing empirical source-receptor relationships (SRRs) while accounting for natural variability. One design approach would use perfluorocarbon tracers (PFTs), which are nonreactive in the atmosphere, to simulate the transport and dispersion of reactive species such as sulfur and nitrogen oxides. Conversion and loss factors would be calibrated using isotopic sulfur and nitrogen compounds with PFTs, in combination with aerometric and deposition observations. An experimental concept is described that determines SRRs for deposition from observations and their interpolation, synthesized by an empirical model. If implemented, the experiment would be very expensive and has high design risk for achieving its goals given present knowledge.Among the points of scientific debate on regional scale air pollution phenomena is the issue concerning source-receptor exposure relationships (SRRs). Research has implicated air pollution at great distances from its origin as an important factor, for example, in acid deposition. These results have stimulated a call for increased emission control over broad industrialized areas of the Northern Hemisphere to reduce deposition levels. Estimated costs for widespread decreases in emissions have been so large that attention has centered on selective emission reductions. Selection of sources would be made to protect certain environmentally susceptible areas. However, implementation of such a strategy requires a specific knowledge of pertinent source-receptor relations.One approach to development of a strategy for selective emission control uses numerical simulation (air quality models). The models are numerical representations of atmospheric processes which intervene between source emission and the deposition of material. These models are required to estimate results of phenomena over subcontinental areas, and as a consequence must be highly simplified. Additionally, many of the processes to be simulated are not fully understood. For verification, the output from models may be compared with available observations, which themselves are incomplete with respect to spatial and temporal coverage and are subject as well to measurement error. For both reasons, the output of physical simulation models cannot yet be considered to provide a reliable description of the SRRs in acid deposition. Discussion of regionwide pollution control opCopyright 1987-APCA tions and opportunities thus has been inhibited by the lack of confidence in modeling results.In view of the limitations of p...
