Ammonia (NH3) is commonly used in various industries and applications, including agriculture, industrial processes, and medical treatments. However, it is important to be cautious of overexposure to NH3, as it can lead to severe irritation of the respiratory organs, eyes, and skin when the concentration exceeds 50 parts per million (ppm) [12, 13]. In addition to its irritant effects, a high concentration of NH3 in the atmosphere can potentially result in a catastrophic explosion.

It is worth noting that NH3 can also be produced as a byproduct of human metabolism. In certain cases, the concentration of NH3 in exhaled breath can exceed 800 parts per billion (ppb). This elevated concentration of NH3 in exhaled breath can be used as a biomarker for renal disease in the field of exhalation diagnosis.

Overall, while ammonia has many important applications, it is crucial to handle it with care to avoid overexposure and its associated health risks
