Minnesota Pollution Control Agency (MPCA) administrators
effectively managed numerous air pollutants over the past two
years. According to Minnesota Public Radio News, these officials
improved air quality in the Twin Cities by focusing on fine
particle pollution. Recent MPCA data showed that the Twin Cities
area averages roughly 10 air quality alerts in most years.
However, there were only four such alerts in both 2011 and 2012.
Air quality warnings are issued if pollutant levels are
unhealthy for certain groups, including people who have
respiratory problems. MPCA official Rich Strassman said that the
recent reduction in the number of warnings is a positive sign
for the state, but noted that the weather also impacted the
agency's calculations. "We can probably attribute it to some
fairly active weather in 2012, where the concentrations just
didn't accumulate over multiple days like we've seen in the
past," Strassman told the news source. The Airgle® PurePal® Plus
