Talk Title: source Apportionment: Making the Most of Environmental Time - Series

Abstract: Source apportionment techniques, most notably receptor modeling and related data visualization methods, provide an often unique description of the relative contributions of different pollutant sources. At the most fundamental level they answer the question of ‘What emission impacts are we having on our environment?’ However, in some of the most sensitive areas, e.g. in sites near large facilities such as metal works, airports and ports, and at busy roadsides where emissions are not always easily managed, they have the potential to be one of the most effective feedbacks for informing, evaluating and shaping mitigation programs.

Here, examples are presented from both previously published studies and on-going work that demonstrate the use of source apportionment as an integrated component of air quality management activities. These include:

• The use of data visualization techniques to enhance preliminary source characterization work.

• The integration of different data sources (e.g. multiple site air quality data and single site air quality and meteorological data) to provide better resolved source descriptions.

• The application of single time-series (peak) and multiple time-series (feature) isolation methods for the quantification of individual pollution events.

• The use of receptor modeling information as an input for pollution event prediction systems, providing early warnings for bad pollution days.
