ST. PETERSBURG, Fla. - Saharan dust has made its way to Florida and officials in Pinellas and Hillsborough Counties are warning certain residents to take heed.
The Pinellas County Air Quality section of Public Works issued an Air Pollution Precautionary Advisory on Wednesday morning due to elevated levels of the pollutant Particulate Matter of 2.5 micrometers or less (PM 2.5). This means there are microscopic solids or liquid droplets in the air that are so small that they can be inhaled and cause serious health problems.
Shortly afterward, Hillsborough County issued a similar advisory.
According to the Environmental Protection Agency, some particles less than 10 micrometers in diameter can get deep into your lungs and some may even get into your bloodstream.
The EPA states that particles less than 2.5 micrometers in diameter pose the greatest health risk.
