To prevent acid rain, you have a slogan, a sentence

Acid rain prevention slogan:

1. Acid rain is the common enemy of all things on earth.

2. The earth doesn’t want to be “jealous” anymore!

3. Everyone has the responsibility to prevent acid rain!

4. In the dark sky, don’t let your sadness turn into tears!

5. Isn’t the sour rain the accusation of the sky?

6. Prevent acid rain and benefit future generations.

Methods to weaken acid rain:

1. Save energy and reduce pollution. Develop a set of basic energy-saving policies to strengthen energy management and develop a set of energy-saving technical policies. Restrictions: Eliminate existing industrial boilers and furnaces with high coal consumption, low thermal efficiency, and heavy pollution.

2. Adjust the structure of civilian fuel and reduce energy pollution. Gradually realize the gasification of civil fuel and gradually realize urban centralized heating.

3. Improve coal utilization technology. Turn high-sulfur coal containing more than 45% sulfur into low-sulfur coal with less than 2.7%.

4. Strengthen the control of automobile exhaust. Formulate exhaust emission standards for various types of vehicles, limit vehicle speeds, improve engine integration and install anti-pollution devices. Implement a regular phase-out system for motor vehicles as soon as possible.

Hazards of acid rain:

Acid rain refers to atmospheric precipitation such as rain, freezing rain, snow, hail, and dew with a pH value less than 5.6. A large amount of environmental monitoring data shows that due to the increase in acidic substances in the atmosphere, cloud water over most areas of the earth is becoming acidic. If left unchecked, the area of ??acid rain areas will continue to expand, and the harm to humans will also increase day by day.

It has been confirmed that sulfur dioxide and nitrogen dioxide in the atmosphere are the main substances that form acid rain. Among the components of acid rain measured in the United States, sulfuric acid accounts for 60%, nitric acid accounts for 32%, hydrochloric acid accounts for 6%, and the rest is carbonic acid and a small amount of organic acids. Sulfur dioxide and nitrogen dioxide in the atmosphere mainly come from the combustion of coal and petroleum. They form acid dissolved in rainwater under the action of oxidants in the air.

According to statistics, about 100 million tons of sulfur dioxide and 50 million tons of nitrogen dioxide are emitted into the atmosphere every year globally. Therefore, acid rain is mainly caused by human production activities and life.
