Ammonia causing Water pollution5 answersAmmonia is a nitrogenous compound that can cause water pollution, leading to eutrophication and deterioration of water quality. It is discharged into natural water bodies by industrial and agricultural sectors. Ammonia pollution can also occur through accidents, such as ammonia pipe leaks, which can result in air and water pollution. Nitrogenous pollutants, including ammonia, can have toxic effects in water, stimulate eutrophication, and interfere with purification processes. Ammonia emissions primarily originate from agricultural sources and contribute to a wide range of environmental problems, including acid deposition, excess nutrient deposition, and climate change. Despite its harmful effects, ammonia emissions have not been subject to stringent control policies, unlike other pollutants. Therefore, it is important to identify emission sources and policy options to reduce the harmful environmental effects of ammonia.
How does ammonia impact the water quality?5 answersAmmonia has a severe influence on water quality and human health. It can lead to excessive proliferation of toxic algae, prevent oxygen from reaching fish's gills resulting in death, and indirectly affect humans through polluted seafood and water. Ammonia can also stimulate phytoplankton growth, exhibit toxicity to aquatic biota, and exert an oxygen demand in surface waters, degrading lake water quality. Additionally, ammonia can impact the conductivity of water during wastewater treatment using membrane distillation technology. Excess nitrogen deposition, including ammonia, can also contribute to water eutrophication, soil acidification, elevated greenhouse gas emissions, and biodiversity loss.
What are the sources of ammonia in freshwater?5 answersAmmonia in freshwater can come from various sources. In lakes, ammonia is released from the sediments, primarily through the deamination of proteins, amino acids, and urea. Fishpond waters can also be a source of ammonia, with emissions occurring from both the water and uneaten feed. Mudflats, despite being near surface water bodies, have uncertain contributions to atmospheric ammonia. Additionally, ammonia can be produced by fish waste, which can be lethal to fish even in oxygen-rich environments. However, an ammonia adsorption product has been developed to remove ammonia from water, extending the life of fish by converting toxic ammonia into ammonium. Overall, the sources of ammonia in freshwater include sediment release, fishponds, mudflats, and fish waste.
