Contents of handwritten newspaper on air pollution prevention and control

The contents of the handwritten report on air pollution are as follows:

Air pollution is closely related to human beings. It has existed for thousands of years since it was cooked and heated by fire. During the industrial revolution, dangerous high-level outdoor air pollution became a problem, and the widespread use of coal led to many serious urban air pollution incidents.

1952 London fog and haze incident is an extreme case. At that time, due to the interaction between residents burning coal, coal for power generation, dirty fuel for transportation, industrial pollution and weather phenomena, pollution enveloped London, and more than 6,543,800 people died in these days. Different pollutants have different sources. In cities, air pollution comes from both inside and outside the city and from far away places.

The main pollution sources in cities include vehicles, natural gas, burning of coal and charcoal, wood used for cooking and heating, and industrial pollution sources still located in cities.

Air pollution is mainly caused by human activities:

There are many sources of air pollution, including natural and man-made. Natural sources include volcanic eruptions, waves, soil dust, natural vegetation fires and lightning. Some of the most common anthropogenic sources include power generation, transportation, industry, residential heating and cooking, agriculture, solvent use, oil and gas production, waste incineration and construction.

Many large industrial sources, such as cement plants, steel plants, power plants, etc., are far away from cities, but because pollutants can spread to far places with the air, they still aggravate urban air pollution. Pollutants discharged by the oil and gas industry and maritime departments can also spread to far places.
