Those <br />people should consider cutting <br />back on their activities. <br /> <br />Ground-level ozone, a key <br />component of smog, is most <br />common in hot weather, when <br />airborne chemicals and exhaust <br />are baked in the sun. This <br />weekend, increasing <br />temperatures from a high <br />pressure system, a nighttime <br />temperature inversion and low <br />wind speeds should provide <br />ideal cClnditionsfor ozone levels <br />to build. <br /> <br />To help reduce them, people <br />cangrive"less, postpone <br />paint,i_n~projects or mowing <br />la,^"ns,;and refuel vehicles in the <br />cqo-i~revening hours. <br /> <br />Fo'r,:rnore information about <br />r~ducin9air pollution, visit <br />CI?8nAir Minnesota at <br />WVj'(.J,hlfl-ei,org/airl <br />resources,html#Factsheets.

PAUL <br /> <br />METRO/REGIONAL BRiEfiNG <br /> <br />TWIN CITIES <br /> <br />Air-pollution alert <br />issued for today <br /> <br />Predicting a spike of ozone to <br />unhealthy levels, the Minnesota <br />Pollution Control Agency has <br />Issued an alr-pollution alert for <br />today in the Twin Cities and St. <br />Cloud areas. <br />The agency reported that <br />high temperatures, clear skies <br />and southerly winds could push <br />the federal Air Quality Index for <br />ozone in the region to 109, a <br />level considered unhealthy for <br />people with heart or lung dis- <br />eases, children, the elderly and <br />people who exercise outdoors. <br />Those people shOuld consider <br />cutting back on their activities. <br />Because of continued hot <br />weather, air quality is expected <br />to remain poor across the Upper <br />Midwest through Sunday. <br />Ground-level ozone, a l<cy com- <br />ponent of smog, is created when <br />airborne chemicals from paints <br />and vehicle exhaust react with <br />each other in heat and sunlight. <br />To reduce ozone levels, pea' <br />pie can drive less, postpone <br />painting projects or mowing <br />
