The Air Quality Index (AQI) for Miami-Dade County is in the Moderate range for ozone, primarily due to the brush fire currently happening in southwest Miami-Dade. While the urbanized areas of the county have experienced wind patterns that have mitigated the effect of the smoke coming from this fire, residents close to the area should take protective precautions.
Wildfires release a large amount of ozone precursors, carbon dioxide, and black carbon into the atmosphere which can cause elevated ozone concentrations. Local particulate matter (PM) instruments are not detecting elevated PM due to the wind pattern, which prevents detection by most of the monitors.
Since smoke is made of a complex mixture of gases and fine particles when wood and other organic matter burns, these microscopic particles can get into the eyes and respiratory system. It can cause health problems such as burning eyes, runny nose, and illnesses such as bronchitis. Fine particles also can aggravate chronic heart and lung diseases.
It is advisable that young children, the elderly, pregnant women, people with respiratory ailments (such as asthma), and individuals who exercise vigorously in the area should be cautious as they may be especially sensitive to Particulate Matter pollution. DERM and the State of Florida Health Department recommend that residents follow the following guidelines during an incident of high smoke or particulate matter levels:
Recommendations:
- Limit outdoor activities and remain in an air-conditioned environment.
- If you run a window unit air conditioner, then keep the fresh-air intake closed to prevent outdoor smoke from getting inside.
- Do not add to indoor air pollution. Do not vacuum, use candles, fireplaces, or gas stoves. Do not smoke.
- Leave the area until the smoke has cleared if you do not have air conditioning or if smoke is likely to get inside your house.
- Avoid activities that put extra demands on your lungs and heart. These include exercising or physical chores, both outdoors and indoors.
- Take all medication according to the doctor’s instructions.
- Dust masks, bandanas, or other cloths (even if wet) will not protect you from smoke.
- Contact your medical provider if you are concerned about your health or if your health worsens.
