Ammonia is toxic to aquatic life which leads to increased amounts of fish deaths. [6] Ammonia pollution also leads to eutrophication. Eutrophication is the growth of algae that kills other aquatic life and creates dead zones. Ammonia pollution affects freshwater and salt water ecosystems differently due to physical and chemical differences.
Data is accumulating that air pollution exposure also affects the central nervous system. [186] Air pollution increases the risk of dementia in people over 50 years old. [187] Indoor air pollution exposure during childhood may negatively affect cognitive function and neurodevelopment. [188] [189] Prenatal exposure may also affect neurodevelopment.
In its Sixth Assessment Report, the IPCC notes that sustainable biofuels, low-emissions hydrogen, and derivatives (including ammonia and synthetic fuels) can support mitigation of CO 2 emissions but some hard-to-abate residual GHG emissions remain and would need to be counterbalanced by deployment of carbon dioxide removal methods.

The United States Environmental Protection Administration defines pollution as "Any substances in water, soil, or air that degrade the natural quality of the environment, offend the senses of sight, taste, or smell, or cause a health hazard. The usefulness of the natural resource is usually impaired by the presence of pollutants and contaminants."
Ammonia in pure form is also applied directly into the soil. Ammonia, either directly or indirectly, is also a building block for the synthesis of many chemicals. Ammonia occurs in nature and has been detected in the interstellar medium. In many countries, it is classified as an extremely hazardous substance. [15]

Environmental chemists draw on a range of concepts from chemistry and various environmental sciences to assist in their study of what is happening to a chemical species in the environment. Important general concepts from chemistry include understanding chemical reactions and equations , solutions , units , sampling , and analytical techniques .
