Primer on Pollution Source Apportionment


Primer on Source Apportionment Primer on Source Apportionment Primer on Source Apportionment

Building an effective air pollution control plan for the cities and the regions, it is important to know the contribution of sources. This is not a easy process, as it involves many steps, some related to field experiments, some related to laboratory analysis, some related to (statistical and predictive) modeling, and some related to linking the results to pollution control planning. Some background notes is explained in the following tables.

  • Pros and cons of top-down (receptor-based) and bottom-up (emissions-based) methods
  • Information and decisions required to conduct top-down (receptor-based) source apportionment
  • Laboratory techniques for chemical analysis of filter samples
  • Elemental markers for various sources detected during chemical analysis
  • Comparison of model requirements, strengths, and limitations of receptor models

We structured the operational steps into a primer, explaining the process of source apportionment using these 2 methods to support an informed air quality management plan. You can download a pdf version of the primer here or browse the pages below.
