Amid concerns over air quality, the Arizona Department of Environmental Quality (ADEQ) has issued a High Pollution Advisory (HPA) in Maricopa County for the weekend of December 21-22, 2024. This alert is specifically for particulate matter 2.5 (PM2.5), commonly known as soot, as levels are anticipated to surpass the federal health standard.
Restrictions Imposed in Maricopa County
The Maricopa County Air Quality Department (MCAQD) has declared a “No Burn Day,” enacting mandatory prohibitions to mitigate air pollution:
- Wood burning in residential fireplaces, chimineas, outdoor fire pits, and similar setups is not allowed, affecting both individuals and businesses with open burning permits, including hotels and restaurants.
- Leaf blowers are banned on governmental properties.
- Operation of off-road vehicles is prohibited.
Health Implications of PM2.5 Exposure
Individuals with heart or lung diseases, seniors, and children are especially vulnerable to particle pollution. PM2.5 particles can infiltrate deep into the respiratory system, potentially causing short-term health issues such as irritation of the eyes, nose, throat, and lungs, as well as coughing, sneezing, runny nose, and breathing difficulties. Prolonged exposure may impair lung function and exacerbate conditions like asthma and heart disease.
Recommendations for Employers and Residents
Employers and Travel Reduction Program Coordinators are urged to implement their HPA Plans without delay. The ADEQ advises the public, particularly those with respiratory conditions, to minimize outdoor activities during the advisory period.
To assist in improving air quality, ADEQ and MCAQD recommend the following actions:
- Visit Maricopa.gov/AQ for more information on reducing air pollution.
- Limit driving, carpool, use public transit, or telecommute.
- Plan transit trips or find carpools at ShareTheRide.com.
- Avoid dust-generating activities, such as driving on unpaved roads.
Understanding PM2.5 and High Pollution Advisory
PM2.5 are fine particles, smaller than 2.5 micrometers, primarily emitted from vehicles, power plants, and industrial operations, along with residential fireplaces and wood stoves.
A High Pollution Advisory indicates pollution levels may exceed federal health standards. Active children, adults, and those with lung issues like asthma should reduce prolonged or heavy outdoor exertion.
