***
Dr. Paul Kubic, a pediatric lung specialist, saw more children in his St. Paul clinic Tuesday than any other day in several weeks. The kids show up with asthma or respiratory diseases, and winter's cold air and viruses make everything worse for them.
The past few days added another complication: bad air.
State officials issued an "unhealthy for all" air pollution alert Tuesday for the Twin Cities, the first time that level has been reached for any air pollutant in Minnesota for at least 25 years.
