Colorless, odorless gas; precursor of NO₂/ozone chemistry; toxic in high concentrations.
✓ measurable with the air-Q Science on request.
Combustion processes (engines, combustion plants), chemical production; also physiological messenger substance in traces.
Occupational and environmental limit values exist; often low ppm ranges.
Irritation, conversion to NO₂ with stronger lung effect; methemoglobin-forming in high doses.
Emission and process control (catalytic converters, SCR).
