The gray haze covering the capital was caused by windblown dust, according to the Utah Division of Environmental Quality.
Utahns in Salt Lake City woke up Saturday morning to dusty, “unhealthy” air, according to the Utah Division of Environmental Quality.
The gray haze blanketing the capital was caused by particulate matter, with the division saying on Saturday there was “a possibility of windblown dust in the area”.
Saturday morning’s air quality index was “unhealthy” due to high levels of particulate matter, known as PM 2.5, according to the business unit’s health forecast, which measures levels of particulate matter and ozone. Ozone AQI reading in Salt Lake City was “good”.
“Try to avoid outdoor activities when dust is being raised. People with existing heart or respiratory conditions should take reasonable precautions,” the department warned on its website.
DAQ measures air quality on a six-point scale, with the AQI ranging from “good” to “harmful”.
