Examples of street environmental pollution: Urgent, urgent

1.Spit. 2.Littering.

3.Small ads.

Air pollution. Governance: People should drive less private cars. Try to get around by bus or bicycle.

Noise pollution. Treatment: People who drive should try not to honk their horns.

White pollution. Treatment: People should use less disposable lunch boxes, disposable chopsticks, and try not to use plastic bags.

Protect the environment, the sun and the moon shine brightly.

De-pollute the rivers and rivers flow forever.

Plastic products are floating all over the sky, and black smoke from chimneys is flying in the sky.

The grass bends over me, and I smile at the grass

It's so dirty on the street

Especially the section of the earth bridge dam

Airport Road is a little better.

Every creek around you!

It is some impurities that are harmful to the atmosphere decomposed by gasoline. There is about carbon dioxide, sulfur dioxide, and so on. The solution is to switch to electric ones, which is the best way now!

Also: the exhaust of the car emits carbon monoxide, == These are serious hazards to the atmosphere, especially sulfur dioxide

Automobile exhaust fumes are discharged through exhaust pipes, crankcases, fuel tanks and vaporizers, and the main pollutants emitted are carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), sulfides, lead (PB) (generally emitted by vehicles using leaded gasoline), benzene and some suspended particulate matter (including carbon particles).

According to statistics, for every 1 kilogram of gasoline burned in a car engine, 15 kilograms of fresh air are consumed, and 150-200 grams of carbon monoxide (CO-8 grams of hydrocarbons, 4-20 grams of nitrogen oxide and other pollutants are discharged.

Carbon monoxide is mainly formed by inadequate combustion of fuel in the cylinder. The volume of the cylinder of the car itself is not large, and only 20% of the air inhaled in the suction stroke is oxygen, which determines that the fuel in the cylinder of the car cannot be fully burned, so a large amount of carbon monoxide is formed.

Hydrocarbons are produced by the evaporation or incomplete combustion of fuel in automobiles and include more than 200 substances.

Nitrogen oxides are produced by the chemical reaction of nitrogen and oxygen in the air at the high temperature of a cylinder.

In gasoline engines, at the end of the compression stroke, the spark plug emits an electric spark that ignites the fuel and air mixture drawn in the suction stroke. Compressed nitrogen and oxygen produce a variety of nitrogen oxides at high temperatures and discharges. For example.

In diesel engines, high temperatures also cause complex chemical reactions between nitrogen and oxygen.

Like pesticides, it can destroy the ozone layer, the "umbrella" of the earth. over.

Carbon dioxide emitted by cars is a major contributor to the greenhouse effect.

Up the mountain – on the mountain; Cows – milk; Bees – Honey.

This should be tailored to local conditions and vary from person to person. However, it is necessary to actively carry out, expand investment, and strive for research and development, starting from changing concepts. Improving energy efficiency, reducing emissions, conserving resources, and protecting the environment are low-carbon concepts and circular economies.

The ultimate solution is for all the people on earth to die.
