HOUSTON (AP) — Smog reached unhealthy levels in the Houston area as state monitors recorded the highest ozone levels in almost nine years.

The Houston Chronicle reports air pollution monitors in nearby Brazoria County measured ozone levels Wednesday of 136 parts per billion, the highest reading seen in the eight-county Houston region since August 2003. Ozone is the key component of smog and can lead to effects ranging from eye and throat irritation to asthma attacks.

The Texas Commission on Environmental Quality reported Wednesday’s severe smog resulted from record heat and stagnant air.
