Boating and SCUBA Accidents, Low-Head Dams, and Beach Renourishment

Another nitrogen-related danger is the narcotic effect that extra nitrogen has on the body. Anyone who has had nitrous-oxide gas at the dentist is already familiar with this effect. Nitrogen narcosis is a danger because it impairs judgment and sensory perception. As with the bends, the degree of nitrogen narcosis is related to how deep a diver goes and how much nitrogen is absorbed into the body.
Diving and ROV

The purpose of any inert, or carrier gas is to dilute the flow of oxygen to the lungs, thereby preventing oxygen toxicity. In air and in shallow diving, nitrogen serves this purpose. However, breathing high partial pressures of nitrogen causes a narcotic, euphoric feeling. This detrimental effect, called nitrogen narcosis, eliminates the use of nitrogen as a breathable gas below depths of about 190 ft.

Hydrogen agriculture belongs to a low-carbon economy (Li, Lou, et al., 2021). As the technology for hydrogen production continues to evolve and develop in fields like energy and medicine, the methods and costs associated with hydrogen production will also inevitably change. This will create favorable conditions for the development of hydrogen in the agricultural field. The safety of H2 for humans is demonstrated by its application in Hydreliox, an exotic, breathing gas mixture of 49% H2, 50% helium, and1% O2, which is used to prevent decompression sickness and nitrogen narcosis during very deep technical diving (Ohta, 2015). Furthermore, hydrogen has been listed as a food additive in China, Japan, and the EU (Shen & Sun, 2019). However, as mentioned above, the use of H2 in existing applications indicates that it is safe and can be used in food.
