The influence of foggy days on human beings.

When there is fog, you can't see anything, your life circle shrinks, and your business is less. What else can you produce?

Disadvantages: fog is harmful to human beings, and its harm to human beings far exceeds its benefits. The harm of fog to human beings is mainly the influence of fog on various transportation and the harm of fog to human health.

1, transportation

For highways, it is no exaggeration that fog is called a "ruthless killer". According to statistics, traffic accidents caused by bad weather such as fog on expressways account for about 1/4 of the total number of accidents.

1July 997 12, Beijing section of Beijing-Tianjin-Tangshan Expressway, foggy, visibility only a few meters. Two consecutive rear-end collisions involving more than 40 vehicles occurred, with 9 people killed and 34 injured.

1997 65438+February 24th, Tianjin section of Beijing-Fuzhou Expressway, due to poor visibility in fog, more than 70 vehicles collided, causing many casualties.

A large-scale fog at 6: 30 on September 4 this year caused a major rear-end collision on the Beijing-Shenyang Expressway. Nearly 100 cars collided, 34 cars were damaged and 5 people died.

In recent years, inland river shipping has been more and more "poisoned" by fog, and the proportion of accidents has soared.

199965438+February 31June 16: 30. The passenger ship "Jianghan 2 1" carrying more than 620 tourists. Braving the heavy fog, we sailed from Nanjing Port to Shanghai, hoping to reach Wusongkou in the early morning of June 65438+1 October1,2000, and watch the first sunrise in the new millennium rise from the sea. Because of the fog on the river, it is difficult to distinguish it from a long distance, and unfortunately it collided with a cargo ship, causing L people to die. Two people were injured and three people were missing.

On June 22nd this year, the passenger ship "Rong Jian" in Hejiang County, Sichuan Province capsized in the Yangtze River due to serious overload, foggy navigation and illegal operation, and 130 people were killed, resulting in the "June 22nd" tragedy that shocked the whole country.

654381in the early morning of October 8, a passenger-cargo collision occurred in the waters of Laozhoutou, Tuqiao Waterway, Tongling, Yangtze River, killing three people and injuring 19 people. When the accident happened, the river was foggy and the visibility was only 700 meters.

Airplanes and flights are no exception. 654381On the morning of October 2, many people in Beijing wanted to take the opportunity to spend the National Day holiday in other places, and they didn't want to be blocked by the fog, so they lost interest. The fog "locked" the Capital International Airport, the flight returned, and more than 3,000 passengers were stranded. According to historical statistics, domestic flights can't take off and land normally, and 78.9% of them are affected by fog, and 57% of them are foreign flights.

The loss caused by fog is amazing. As far as Chongqing, a mountain city known as the foggy city is concerned, the economic losses caused by traffic accidents and traffic jams caused by fog every year before the 1990s were more than 30 million yuan. 1986 The plane could not take off and land normally, 18 Foreign economic delegations canceled their visit to Chongqing, which seriously affected Chongqing's opening up and economic development. As for now, the loss is far more than that.

On April 7th, 2000, our project team came to the Accident Section of Minhang District, visited the Chief of the Accident Section, and asked for information on traffic accidents caused by fog from June 65438+1 October1day to April 7th, 2000. The accident was: in March, 2000, a van collided with a motorcycle in a section of Yuanjiang, Minhang, killing 1 person. The main reason is that the weather is foggy and I can't see clearly, so I have to take emergency braking, but it's too late.

All the above examples can show that fog is very harmful to traffic, which affects all sea, land and air traffic.

2. Hazards of fog to human body

Fog is harmful to human body, but different degrees of fog have different effects on human body. The London smog in Britain, the light pollution in Los Angeles, and poisonous fog like this have caused many deaths and left many sequelae. The fog in Shanghai has little effect on human body, basically has no effect on healthy people, and only affects the old, the young and the sick. Generally, the main symptoms caused by inhaling fog in foggy days are runny nose, pharyngitis, a small amount of cough and expectoration.
