Summary of Missouri Air Quality in 2014

Archives

The last 4 posts have looked at air quality data for 20 Missouri counties for the years 2003-2014, plus 1983 and 1993 for a longer term perspective. They clearly show that Missouri has made dramatic progress in improving its air quality, but that more work remains to be done. This post summarizes the findings for 2014.

Fifteen out of twenty Missouri counties had no unhealthy air days in 2014. Most never had > 20% of unhealthy air days at any time covered by these statistics, only four did: St. Louis City, St. Louis County, Iron County, and Jefferson County. All four have cut the number to less than a quarter of its maximum value. The county with the highest percentage of unhealthy air days in 2014 was Jackson County, the location of Kansas City, at 14%. While that is a small fraction of total days, the trend is troubling, showing a persistent increase across the entire period (see chart in Few Unhealthy Air Days in Most Counties).

A soapbox moment:

I regard good air to breath as a basic human right. It goes right in there with “life, liberty, and the pursuit of happiness.” How can you live, be free, and pursue happiness if you don’t have good air to breathe? I very well understand that our air will never be pristine, for there are too many natural phenomena that put gases and particulates into it (like forest fires and wind-blown dust). But none of us should have to live with asthma or chronic lung disease simply because others of us pollute and refuse to clean up our act.

If one takes a very long term perspective, it must be acknowledged that air pollution was not monitored reliably prior to the 1980s. However, the photos from Black Tuesday in 1939 show that St. Louis, at least, has come a very long way indeed. That is very good news for us all. The success our nation has achieved improving local air quality and background air pollution offer hope that we can successfully address other important environmental problems, if only we will.

End of soapbox moment.
