Air pollution chemistry
Air pollution chemistry is the study of harmful substances present in the atmosphere of Earth that can cause adverse effects to the environment and living organisms.[1] It is closely related to atmospheric chemistry, the study of the chemistry of the atmosphere of Earth. Human activities such as industrial processes, vehicle emissions and burning releases various pollutants such as carbon dioxide, Carbon monoxide, sulfur compounds, organic volatile substances and nitrogen oxides. They can exist in various physical states such as particulate matter, liquids, gases, vapors and etc.[2]
Chemistry
Theses pollutants can interact with the atmosphere to produce other secondary pollutants such as ozone. Theses molecules such as the nitrogen oxides can also interact with the atmosphere to produce effects such as acid rain.[2][3]
Nitrogen oxides
Nitrogen dioxide and nitric oxide are a group of stable molecules called nitrogen oxides. They are released into the atmosphere mainly as a result of combustion and are found in elevated concentration levels in urban places. Nitric oxide will readily react with nitrogen dioxide to form ozone. When it rains, they are removed from the atmosphere and contributes to acidic rain.[3]
Catechol
Catechol is a molecule that is derived from benzene and is the precursor for the molecule 4-nitrocatechol. This is compound common in atmospheric brown carbon which absorbs sunlight and thus alters how our atmosphere radiates off sunlight.[4]
Importance
The study of how pollutants can affect the chemistry of Earths atmosphere is impacts human activities, health and the environment. It is important to study their effects to developed strategies to reduce pollution and manage air quality.[2][5]
