On the main source of carbon monoxide 8-hour average value
All things in the world are related to the environment. The main source of carbon monoxide 8-hour average value is related to the quality of the atmosphere and cannot be ignored.

First, traffic is the key source. Since the car is in the world, the streets and alleys, the car water Ma Long. When the gas engine is running, carbon monoxide is produced. Petrol, diesel and other fuels are in the engine, or due to incomplete combustion, carbon is not fully oxidized, and carbon monoxide is dispersed in the air. Like the main roads in the city, the daily traffic flow is like a flow, and at the peak, the exhaust gas rises, and the carbon monoxide content rises sharply, adding to the 8-hour average.

In addition, industrial production is also an important factor. In many factories, metallurgy, chemical industry, in the production process, fuel combustion, chemical reactions and many links, all have the possibility of carbon monoxide escaping. When blast furnace ironmaking and coke are burned, if the conditions are different, carbon monoxide becomes a by-product, pervades the factory area and surrounding areas, and gradually enters the atmosphere, affecting the 8-hour average.

Residential fuel utensils should not be underestimated. In rural areas, there are people who use coal and firewood as cooking and heating utensils. During combustion, if the ventilation is poor and the oxygen supply is insufficient, carbon monoxide is quietly generated. Although it is scattered, it accumulates in small amounts. In the air in the area, it is also the influence factor of the 8-hour average.

Wildfires in the mountains and forests. Occasionally, plants burn and carbon monoxide also rises with the smoke. Although it is not normal, once it rages and has a wide range of effects, the amount of carbon monoxide generated will disturb the 8-hour average value of carbon monoxide in the surrounding and even farther areas.

In summary, the main sources of carbon monoxide 8-hour average value, transportation, industry, residential appliances and wildfires in the mountains and forests, etc., all need to be treated with caution. All parties work together to protect the atmosphere and the environment.
