The use of chemical fertilizer containing anhydrous ammonia can lead to exposure. Outdoor exposure to high levels of anhydrous ammonia can result from leaks and spills at production plants and storage facilities, and from pipelines, tank trucks, railcars, or ships and barges that transport ammonia.
Nitrogen is an essential nutrient that is required by all plants and animals for the formation of amino acids. One such form is ammonia (NH 3). Ammonia may be taken up by plants or oxidized by bacteria into nitrate (NO 3 -) or nitrite (NO 2). Ammonia (NH3+) is a colorless gas with a strong pungent odor.Ammonia will react with water to form a weak base. The term ammonia refers to two chemical species which are in equilibrium in water (NH 3, un-ionized and NH 4 + , ionized). Tests for ammonia usually measure total ammonia (NH 3 plus NH 4 +).itrogen is an essential nutrient that is required by all plants and animals for the formation of amino acids.
