The overall objective of this research project is to develop a complete real-time monitoring system for acidity and soluble components in airborne fine particulate matter (PM). The system will be readily transportable and capable of continuous field operation.

The specific objectives of this research project are to: (1) automate the operation of the PMSCS-IC system; (2) integrate the PMSCS-IC system into a continuous ambient fine PM mass and composition monitoring system developed previously in this laboratory; and (3) build and test the system in both indoor and outdoor environments.

This is one of the projects funded by the New York University (NYU) PM Center. The progress for the other projects is reported separately (see reports for R827351C001 through R827351C015).

Progress Summary:

The results of concentrated ambient particle (CAP) data from February 25, 2004 to March 10, 2004, show that SO42- was about 68.3 ± 14.7 percent (mean ± standard deviation) of total anion content, whereas NO3- (16.4 ± 10.4%) was based on only 72 samples collected in 9 days (6 hours per day). More sample analyses are underway. It is well known that ambient PM nitrate contents are underestimated from the current filter-based sampling technique. Alternatively, gaseous NO2 might transfer into CAPs during the PM concentration process. Real-time monitoring systems such as PMSCS-IC should have an advantage over the filter sampling in this regard. The PMSCS-IC system can be assembled into a continuous PM2.5 monitoring system (designed in a previous U.S. Environmental Protection Agency project) as a detachable element and parallel to other monitoring elements such as a PM-bound water detector, organic carbon/elemental carbon monitor, NOx monitor, SOx monitor, and so on.
