Progress Reports

Year:   2019  2018  2017 

This year, the Characterizing Urban- and Finer-Scale Spatial Variability for Select Volatile Organic Compounds (VOCs) Superfund Compounds Project focused on building and testing a multi-channel gas chromatography – mass spectrometry (GC-MS) instrument for mobile measurements of airborne VOCs. The research team presented this product at the 2019 SRP annual meeting in Seattle (Dang et al., 2019). Key hardware components were purchased or fabricated, and the core unit has been assembled. Electronics and the associated software control programs have been integrated into the instrument.

In addition, the Project used lab-based testing to optimize performance and test key metrics such as analyte detection limits. Additional measurements for ultrafine particle (UFP) number concentration and black carbon (BC) mass concentration were conducted in the study neighborhoods to understand traffic emission impacts (a confounder when examining emissions from Superfund sites), and this information will be used to refine the mobile measurement strategy (Yeager et al., 2019).
