Smog is a combination of sunlight reacting with nitrogen oxides and at least one organic compound, which are molecules that contain carbon and hydrogen atoms. Smog is causing the oxygen to change, creating it to be difficult to breathe. Sometimes the density of smog can not be noticed in the air, but in certain areas of the world daylight looks like the night sky. [1]

Pollution plays a huge role into smog because countries, most notably China, has a huge number of energy power plants causing all that excess waste to enter the atmosphere and merging with the air we breathe. As of today, so much is being done to find solutions to removing the smog, but how long it will take to clean the damage will take a long period of time.[2]

Reasons for appearance

Smog is the mixture of smoke and fog in the air and in our atmosphere. Smog is very noticeable because of the amount of multiple pollution that get mix together with the air we breathe in constantly. Smog which occurs mainly because of air pollution, can be toxic causing the air to we breathe in to be difficult and dangerous.[1]

The main source to why we have so much smog released directly into the air is because of vehicles containing diesel and other gasoline, industrial plants, activities such as smoking cigarettes, and heat.[3]

Exposure to smog

Being exposed to smog can harm the human body in such ways as:[1]

  • Being responsible for lung cancer
  • Being known to make the lungs burn
  • Being known to swollen the lungs
  • Being known to cause an asthma attack
  • Being known to cause the eyes to itch and become watery

Air pollution

Air pollution plays a huge part into smog because if anything were to cause the air to be polluted then it can strengthen the effects of smog. With so many ways for the air to be polluted there are also many effects that come along in such examples as:

  • What causes air pollution[4]
  1. Emissions from industries
  2. Burning fossil fuel
  3. Mining
  1. Global warming
  2. Acid rain
  3. A decrease in the ozone layer

Beijing conflict with smog

Beijing’s air is among the worst in the world, and much of the smog comes from industrial pollution and the burning of coal. The smog problem in Beijing is largely blamed on coal burning power plants, industrial pollution and the huge number of cars that a driven on a daily basis. On December 19, 2015, the government issued a level 4 red alert, the highest level of a 4 tier warning system in the Chinese government. The alert caused schools, jobs, and even some local roads to be closed. The smog was expected to cover a wide area of cities due to the the strength of the wind pressure. [2]

The Chinese's government gave the plan to reduce hazardous exposure from coal powered plants by removing half of their coal plant sometime by the next five years. Unfortunately, do to the amount of work that needs to be done before the process were to begin, it will take until 2030 before seeing the decrease of coal power plants. [5]

Components to forming Smog

Extreme heat coming from the high temperatures, natural sunshine and smooth wind pressure plays a huge part in the formation of smog. When deadly chemicals and burnt fuel are released and sent into the atmosphere it will collect heat over time. When natural sunlight and heat reacts with these deadly chemicals and burnt fuel in the atmosphere, smog is formed.

Common products that gets released into the atmosphere [6]

Air fresheners
Disinfecting chemicals
Exhaust running vehicles
