Ammonia detection: NEVER mix ammonia with chlorine bleach or products that contain chlorine. This produces extremely dangerous toxic chlorine vapor that may be fatal.

Ammonia Detection and Dangers of Working Where Ammonia is Present

Ammonia is corrosive. The severity of health effects depends on the route of exposure, the dose, and the duration of exposure. Exposure to high concentrations in the air causes immediate burning of the eyes, nose, throat, and respiratory tract and can result in blindness, lung damage, or death. Inhalation of lower concentrations can cause coughing, and nose and throat irritation.

Swallowing can cause burns to the mouth, throat, and stomach. Skin or eye contact with concentrated ammonia can also cause irritation and burns.

Ammonia in the environment comes from both natural and manmade sources. It occurs naturally at low levels throughout the environment, released from the breakdown of organic waste matter. Local concentrations may be elevated where there is a lot of animal waste, such as in intensive farming environments for cattle, pig and chickens. Non-agricultural sources include sewage sludge, industry, and petrol vehicles fitted with catalytic converters.
Ammonia gas does not remain in the environment for long; it rapidly reacts to form ammonium compounds.

What Happens to Ammonia When it Enters The Environment

Ammonia does not last very long in the environment. Because it is recycled naturally, nature has many ways of incorporating and transforming ammonia. In soil or water, plants and microorganisms rapidly take up ammonia. After fertilizer containing ammonia is applied to the soil, the amount in that soil decreases to low levels in a few days. In the air, it will last about 1 week.

Ammonia has been found in air, soil, and water samples at hazardous waste sites. In the air near hazardous waste sites, it can be found as a gas. Ammonia can also be found dissolved in ponds or other bodies of water at a waste site. It can be found attached to soil particles at hazardous waste sites. The average concentration of ammonia reported at hazardous waste sites ranges from 1 to 1,000 ppm in soil samples and up to 16 ppm in water samples.
