Impact/Purpose:
The goal of this task is to develop methods and models to reduce the uncertainty in quantifying local and regional air pollutant source impacts on ambient samples collected in speciated PM, air toxic, and semi-continuous measurement networks. A combination of high resolution sampling, organic and inorganic analytical methods, and models will be developed and evaluated to reduce the uncertainty in source apportionment:
(1) semi-continuous inorganic species sampling
(2) inorganic analysis
(3) organic analysis for medium flow samples
(4) multivariate receptor models for ambient samples
(5) regional and local models
In addition, this task contributes to two additional tasks that have research focused on reducing the uncertainty in source apportionment: Identify Sources of Human Exposure (21176), and NAAQS implementation (21179).
Description:
This extended abstract reports the first successful attempt to quantitatively measure all the major species of PM2.5 on a semi-continuous basis. Comparisons are made between both PC-BOSS integrated species concentration measurements with semi-continuous species measurements and of measured semi-continuous mass with constructed semi-continuous mass.
