Monitoring air quality in Minnesota: An overview and applications for health professionals
Cassie McMahon, Environmental Analysis and Outcomes,
Minnesota Pollution Control Agency, Duluth, MN
The Minnesota Pollution Control Agency monitors outdoor air quality at over 50 locations across
Minnesota. The data collected from air monitoring sites are used to determine whether Minnesota meets
federal and state air quality standards and health benchmarks, to forecast and report daily air quality
through the Air Quality Index, and to track trends in air pollution levels over time. The purpose of this
presentation is to provide an overview of the MPCA’s ambient air monitoring network and to share
current and historical monitoring results. This presentation will also highlight available resources for the
public to track and monitor air quality conditions in real-time. Access to real-time air quality information
can help individuals make decisions to reduce their exposure to unhealthy levels of air pollution.
Calibrating concern about PAHS in urban air
using monitoring and modeling
Kristie M Ellickson, Cassie R McMahon, Greg C Pratt, Carl Herbrandson, Mike L Krause, Christina M
Schmitt, Wyatt J. Hedine, Paul D Swedenborg, Charlie J Lippert
This interagency project aims to characterize air concentrations of vapor and particle-phase PAHs
spatially and temporally in an inner city community and a rural site, to investigate sources, estimate
potential health risks, and compare measured and modeled concentrations. Three existing ambient air
monitoring sites were chosen for active air samplers. Siting of 16 cylindrical passive air samplers (Wania
et al 2003, Schrlau et al. 2011) was informed by modeled concentrations, community input, potential
Environmental Justice areas, and proximity to known pollutant sources and sensitive receptors.
Air sampling began in June 2013,the beginning of meteorological summer. Active samples are collected
for 72 hour durations every 12 days, and passive samplers are deployed continuously for a sampling
duration of 3 months, over a total sampling period of 2 years. Preliminary data will be presented.
