KC-TRAQS RESEARCH PROJECTKC-TRAQS RESEARCH PROJECT

2Note: Data results are for research purposes only and not for regulatory purposes.

Purpose:…to characterize the impact of local air pollution sources (PM2.5) in and around the Argentine community including the neighborhoods of Turner and Armourdale.

What is it?KC‐TRAQS is one year air quality study that utilizes several measurement instrument approaches at multiple locations in the study area.

KC TRAQS RESEARCH PROJECT




1. What is the extent of air pollution in the Argentine (KS) neighborhood and the broader SE Kansas City, KS area?

2. Can the impact of local air pollution sources in Argentine (KS) neighborhood and the broader SE Kansas City, KS area air quality be identified and quantified?

3. What is the variability of the rail‐yard and other transportation air pollution impacts, under different meteorological conditions and source activities?

5

• A field study using stationary monitors and mobile measurements to collect BC and PM2.5 data to characterize the impact of local air pollution sources.

• A mobile monitoring campaign using an instrumented electric vehicle and a support vehicle to collect BC, ultrafine particulate (UFP), and nitrogen dioxide (NO2).

• A screening model to assess spatial/temporal coverage of measurement sites.

To determine answers to these questions, the study included: • A complimentary citizen science program using personal sensors and

computer modeling tools as a comparison to the field study data;


KC‐TRAQS ‐ three monitoring approaches;

• Data shown below represent more than 600 Teflon filters collected over the study period (~ 1 year).

• Some spikes (i.e., high values) were noted but not on an on-going consistent basis.

• Comparing the data (shown on the left) with PM2.5 data collected at the JFK NCore site (shown below), preliminary results indicate consistent data trend.

• While data collected during KC-TRAQS are not directly comparable to the National Ambient Air Quality Standards (NAAQS), preliminary results indicate air quality concentrations are below the standard.

• The data are not directly comparable to the NAAQS since data used for setting the NAAQS standard rely upon 3-years worth of data. KC-TRAQS data is for a single year. Meteorological conditions can vary significantly from year-to-year which is why comparing different data sets may be problematic.

Air MonitoringLevels are measured by air monitors located around the state.

•Established Spring of 2015

•Engage communities in air pollution awareness

• Increase air pollution monitoring coverage

• Advance EPA's ability to measure and communicate air pollution information in real-time at lower cost and maintenance.

This is a research and educational air monitoring system with low cost instruments and the measurements should not be compared directly official air quality standards.
