NO2 (nitrogen dioxide)
Toxins · Air pollution
High priority
Bottom line
Read Off Label rates NO2 (nitrogen dioxide) a HIGH avoidance priority (7.6/10) based on strong evidence of high harm magnitude and med-high chronic exposure prevalence.
Gruenwald 2023 attributed ~12% of US childhood asthma to gas stove exposure, driving 2023 regulatory debate.
The intervention here is reducing exposure, not adding a compound.
What this is
Gruenwald 2023 attributed ~12% of US childhood asthma to gas stove exposure, driving 2023 regulatory debate. Induction cooking avoids the combustion source entirely. Vented range hood is second-best; recirculating hoods do nothing for NO2.
Mechanism
Reddish-brown combustion gas from vehicles, gas cooking, industry; reactive oxidant; airway irritant; forms ozone and secondary PM2.5; indoor source: gas stoves (4x outdoor concentration during use)
Dose & route
Range hood use, induction cooking, no-idling around kids
