Acetone is flammable, a dangerous fire risk. It is a narcotic in high concentration and has a low to moderate toxicity by ingestion and inhalation. Acetone is miscible with water and evaporates rapidly in air.
Ammonia is a colorless gas with a sharp intensely irritating odor.
It is used to make fertilizer, animal foods, synthetic fibers, glues and explosives. It is also used in the treatment and refining of metals. Ammonia is a nose and throat irritant and high level short term exposure may result in long term respiratory problems. It is lighter than air and very soluble but non-persistent in water with a half life of less than 2 days. Under most natural conditions of pH and temperature total ammonia is moderately toxic to aquatic life.
