The Iowa Department of Natural Resources has issued an Air Quality Advisory for all Iowa counties until 7 this (Wed) evening due to Canadian wildfire smoke.
Ozone levels near EPA health standards are expected to increase throughout the day, and persist into the early evening hours. Elevated levels of fine particulates and ozone may be a concern over the next several days as smoke moves through the state.
The DNR recommends those with respiratory or heart disease, elderly individuals, and children limit prolonged outdoor exertion until air conditions.
