About Nitrogen Dioxide
A reddish-brown gas from burning fuel, can irritate airways.
Measured in ppb
Health Impact
Members of sensitive groups may experience health effects. The general public is not likely to be affected.
Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
What Is a Safe Level of NO2?
By the EPA Air Quality Index, nitrogen dioxide is Good — safe for everyone up to 53 ppb (AQI 0–50). From 53 to 100 ppb is Moderate (AQI 51–100): acceptable for most people, though unusually sensitive individuals may notice symptoms. Above 100 ppb the air turns Unhealthy for Sensitive Groups and EPA health guidance applies.
Bakersfield is currently at AQI 129 (≈249 ppb, estimated) for NO2 — above the safe-for-everyone threshold, so sensitive groups should limit outdoor exposure until levels drop.
Thresholds are the official EPA AQI category breakpoints for nitrogen dioxide (1-hour standard). The current concentration is estimated from the measured AQI sub-index; the exact value within a band is not recoverable from the index alone.
Sources of NO2
• Vehicle emissions (cars, trucks, buses)
• Power plants and industrial boilers
• Off-road equipment and engines
• Residential heating systems
