Indoor air quality Indoor air quality concerns have increased
because energy conservation measures have required buildings to
be “tighter.” This means polluted air has a harder time escaping
buildings. Air pollutants may cause respiratory diseases, cancer
and other health effects. The American Lung Association has
information on what to do to prevent indoor air pollution as
well as what to do if you believe you already have a problem.
Outdoor air quality Dakota County does not play a role in
outdoor air quality. For information on outdoor air quality,
visit the Minnesota Pollution Control Agency.
