What's up, Forsyth?

What’s Up, Forsyth? In this blog post, we explain how the air pollution and airborne pollen levels are changing seasonally. We also compare Forsyth County’s air quality and pollen season in 2024 with 2023 and share tips for reducing air pollution exposure this winter. How is our air quality changing this time of year? Ground-level ozone season (the period of time when we monitor and forecast for ozone) lasts from March 1 st to October 31 st . This is because sunlight and heat are needed for it to form. Between November 1 st and February 28 th /29 th , ozone concentrations are much lower since our days are shorter and colder, and it is not necessary, nor required by the Environmental Protection Agency (EPA), to monitor for ozone in North Carolina during this period. Particulate matter (PM) concentrations can be high any time of year, therefore, we monitor PM and provide the air quality forecast for fine particulate matter (PM2.5) year-round. PM levels are generally higher in win...

  It’s that time of year again, and those who are not offered yard waste pick up may be left wondering what to do with all the leaf litter.   Leaf burning is seen as a solution for some, but it may be illegal depending on where you live . Even where the burning of leaves and other vegetation is generally allowed, there are specific conditions that must be met, including a code green or yellow air quality forecast for that day. To learn more, check out the Forsyth County Office of Environmental Assistance & Protection webpage on residential burning . In addition to the legal considerations, burning leaves and other vegetation is a potential fire hazard. It also creates air pollution by producing toxic gases (like carbon monoxide, nitrogen oxides, and hydrocarbons) and particulate matter, which are tiny, inhalable solid particles and liquid droplets, some of which are even small enough in diameter (<2.5 microns) to enter the bloodstream. Inhalation of these particl...
