Can someone to explain me what is the harm to health due to NOx high concentration (I found about 60-80ppm of NOx in the air, CO was 0 ppm) in the room where we perform fusing process? The question is very serious for me. What are possibles effects?

NOx is a term for nitrogen oxides that include nitrogen dioxide NO2 and nitrogen monoxide NO. Typically they are produced in combustion processes where nitrogen can be oxidised.
Exposure can lead to nose and eye irritation, lung complaints (pulmonary edema, bronchitis and asthma). Long term exposure can lead to pneumonia pumonary fibrosis and emphysema.

I would suggest increasing the ventilation in the room substantially or place localised extraction close to the process.
