Ammonia:This is a colorless gas known for its pungent odor. It is generated by both human activity and natural processes, easily dissolves in water, and evaporates rapidly. Liquid ammonia is commonly found in various household cleaning products. It can irritate the skin, eyes, nose, and throat. High concentrations in the air can cause severe irritation to the skin, eyes, throat, and lungs, and in extreme cases, may lead to blindness, lung damage, or even death. Inhaling lower concentrations can result in coughing and irritation of the nose and throat. Ingesting ammonia can cause burns to the mouth, throat, and stomach.The annual production of ammonia by humans is nearly equivalent to that occurring naturally. It is naturally produced in soil through the action of bacteria, the decomposition of plants and animals, and animal waste. Ammonia is crucial for various biological processes. Most of the ammonia synthesized in chemical plants is used for manufacturing fertilizers. The remainder is utilized in producing textiles, plastics, explosives, pulp and paper, food and beverages, household cleaning products, refrigerants, and other goods. Additionally, it is used in the formulation of smelling salts.
