About 80 percent of all manufactured ammonia is used as fertilizer. It supplies vital nitrogen to soil, a process that sustains food production for half the global population.

Combining these common cleaners produces highly toxic chloramine gas. Inhaling these fumes causes severe respiratory damage and can be fatal without proper ventilation.

Smelling salts release sharp ammonia gas that irritates the nasal membranes. This triggers an involuntary inhalation reflex, boosting oxygen to the brain to wake the patient.

Ammonia is a toxic byproduct of protein metabolism. The liver converts it into water-soluble urea, allowing the kidneys to safely filter it from the bloodstream into urine.
