Very unhealthy' air expected in Phoenix on New Year's Day

Doctors warn of worsening air quality in Phoenix this New Year

PHOENIX (AZFamily) — It’s no secret that the air quality across Phoenix has been bad over the last couple of weeks. Now doctors are warning it will likely get even worse with the New Year’s celebrations.

Phoenix usually sees its highest air pollution levels on New Year’s Day. That’s because of a combination of fireworks and people burning wood around the holiday.

You’ve likely noticed that brown haze sitting over the Valley for many days this month.

The Arizona Department of Environmental Quality (ADEQ) has issued a PM-2.5 High Pollution Advisory for the Phoenix Metro Area on Tuesday and Wednesday and has issued a PM-10 High Pollution Advisory for the Phoenix Metro Area on Wednesday.
