SALT LAKE CITY — Wildfire smoke is helping raise soot and ozone levels around Utah.

Ozone levels have just risen above the safe threshold in Salt Lake and Davis counties. At 83 parts per billion, it’s considered unhealthy for anyone with asthma or respiratory problems.

Ozone is a lung irritant that can also damage crops and trees. Doctors say it can provoke heart attacks or strokes for people with medical problems.

The invisible gas is formed by chemical reactions in sunlight from tailpipe or other emissions.

Air monitors maintained by the Utah Division of Air Quality say ozone readings are fast approaching or exceeding the health limit in Box Elder, Davis, Duchesne, Salt Lake, Tooele, Uintah, Utah and Weber counties.

Washington County was hovering just under the limit.
