Photochemical Smog
Photochemical smog may be a sort of smog produced when ultraviolet from the sun reacts with nitrogen oxides within the atmosphere. It visible as a brown haze, and is most prominent during the morning and afternoon, especially in densely populated, warm cities. Cities that have this smog daily include l. a., Sydney, Mexico City, Beijing, and lots of more.
Photochemical smog forms from a posh process, however the source of it's quite apparent. the most important contributor is automobiles, while coal-fired power plants and a few other power plants also produce the required pollutants to facilitate its production. Thanks to its abundance in areas of warmer temperatures,
photochemical smog is commonest within the summer.
It forms within the morning when an incredible number people are driving their vehicles to figure. Nitrogen oxides produced within the car engine are introduced into the atmosphere, which can combine with water to make aqua fortis or react with sunlight to supply singular oxygen atoms, which then combine with molecular oxygen to supply ozone. The aqua fortis may precipitate to the world leading to acid precipitation, or remain within the smog. Thanks to the direct production of it by vehicles, the smog forms over cities where many of us may encounter its adverse
health effects.
Hotter days mean more photochemical smog, especially within the densely populated cities like those mentioned above. As more and more urban populations arise round the globe, this problem is merely expected to extend .
