Gaseous ammonia emissions enter Earth’s soil and water through both wet and dry deposition. Aqueous ammonia, another form of the compound, may seep directly into the ground or flow into aquatic ecosystems. Both terrestrial and aquatic ammonia pollution decrease biodiversity mainly through the process of nitrification.
Other agrochemicals such as pesticides and fungicides can enter environments from agricultural lands through runoff and deposition as well. Pesticides such as DDT or atrazine can travel through waterways or stay suspended in air and carried by wind in a process known as "spray drift". [23]
Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir.

Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH + 4][OH −
The cleanup was ordered for properties near the Tucson International Airport at the National Guard base, and a property owned by the Air Force. The EPA gave the Air Force 90 days to design a long ...
This process is known as volatization or air stripping. Water is deposited into the system through the top and air is ventilated in through the bottom. Water that reaches the bottom of the system is typically considered treated, but additional testing may be done to determine if it is safe for consumption. [1]
Ammonia is a typical refrigerant and may be used as the primary working fluid. Compared with water (which can also be used as a refrigerant), ammonia makes use of relatively high pressures requiring more robust and expensive equipment. In air standard cycles as in gas turbine cycles, the working fluid is air. In the open cycle gas turbine, air ...
Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
