E209 refers to heptylparaben in food contexts (not permitted in EU foods); “E209 member” on an ambulance report would be an unrelated internal code, not the additive.
Is nitrogen oxide a greenhouse gas?
Nitric oxide (NO), often called “nitrogen oxide,” is not considered a significant greenhouse gas; nitrous oxide (N2O, a different nitrogen oxide used as E942) is a potent greenhouse gas.
What is the formula for nitrogen oxide?
The common “nitrogen oxide” in this context is nitric oxide, with the formula NO (other nitrogen oxides include NO2 and N2O).
Where does nitrogen oxide come from?
It’s formed during high‑temperature combustion (e.g., engines, power plants) and produced industrially by catalytic oxidation of ammonia (Ostwald process).
Is nitrogen oxide harmful?
Yes—NO and NO2 are respiratory irritants, and high exposures can damage the lungs; they are regulated air pollutants.
What does a catalytic converter turn nitrogen oxide into?
Automotive three‑way catalytic converters reduce NOx primarily to nitrogen (N2) and oxygen (O2), often yielding N2, CO2, and H2O using CO and hydrocarbons as reductants.
