1, Tian is engaged in environmental protection.
She spent more than 90,000 yuan at her own expense and recycled 65 tons of used batteries. When she learned that waste batteries were harmful to human beings, she decided to recycle them at her own expense. She made 3,000 banners with green banners, and wrote down the address and telephone number of recycling used batteries: she made 600 transparent recycling boxes of used batteries and 50,000 environmental protection proposals, which were distributed to schools all over the city.
In Xinxiang Daily, I personally issued a proposal entitled "Don't spoil the earth again". Since then, Tian, with the simple feelings of an environmental volunteer and unprecedented concern for environmental protection, has walked the streets to recycle used batteries at a price of 2 cents a year. She also organized a large number of environmental protection publicity activities, using Earth Day, Environment Day and holidays to promote environmental protection, and let more people know the harm of used batteries through television and newspapers.
In the past five years, she personally invested more than 90,000 yuan to recycle 65 tons of used batteries, saving nearly 7 million square meters of land from the pollution of used batteries. Second, actively carry out various environmental publicity practices and environmental education activities. Tian used holidays to organize large-scale environmental protection publicity activities at his own expense throughout the province. In Zhengzhou alone, Xinxiang organized 38 large-scale activities, such as "10,000 people sign the green Olympic bid" and "Life Network loves environmental protection", with 260,000 participants.
At the same time, she also volunteered to teach environmental protection knowledge to college students. In recent years, Tian visited more than 1 10 schools nationwide, and publicized environmental protection knowledge for more than 300,000 students, explaining the harm of used batteries, with a direct audience of more than 3.6 million people. Every winter and summer vacation, Tian Du organizes environmental protection volunteers to inspect environmental protection topics such as white pollution, river pollution and wetland protection at his own expense.
In order to protect the mother river, Tian led more than 30 college students to walk150km along Weihe River, Renmin Shengli Canal, * * Production Canal, Qinhe River, Yellow River and other rivers, and conducted water pollution and water quality analysis. They fought face-to-face with the illegal sewage discharge behavior of sewage discharge enterprises and submitted 24 test reports to the higher-level environmental protection department, which provided a good foundation for further protecting the mother river and purifying the water source.
2. Wu Qingxian-Wu Qingxian's story of ecological poverty alleviation in grassroots old party member.
Sizhai Village in Shuangjiang, Liping County is a Dong village which is beautiful because of its trees, and has been listed in the list of traditional Chinese villages. Wind and rain bridges, drum towers, schools, Dong people's houses in villages and firewood for Dong people's heating in winter are all made of mountains. At the head of the village, there are old trees and streams. The village is surrounded by ancient trees, and the continuous fir trees are tall and straight, guarding this Dong village every day.
Thinking of the source of drinking water, the beauty of Sizhai Village is full of great contributions from the "King of Guizhou Afforestation" and Wu Qingxian, who was born in party member.
More than 30 years have passed, from giving up commercial afforestation in the year of no doubt to infatuation with the past. Wu Qingxian planted trees to protect the green, rain or shine, and saved tens of millions of yuan of green wealth in the mountains. Although he is poor, he refuses to cut down trees for himself easily. But when public welfare undertakings and Dong's family needed wood for building houses, he did not hesitate to donate it. He touched the villagers with persistence, perseverance, selflessness and dedication, and made the cause of tree planting and green protection a pillar industry towards a well-off society.
According to statistics, by the end of 20 15, Wu Qingxian had planted more than 5 million trees and 55,000 mu of trees, with a total timber volume of 250,000 cubic meters and an economic value of 25 million yuan, which drove villagers to plant more than 50,000 mu, and the forest coverage rate of Shuangjiang River increased from 47% in 1984 to 75% now. Because the afforestation area is the first in Guizhou and the second in the country, Wu Qingxian is known as the "king of afforestation in Guizhou". He was awarded the "National Greening Medal" by the National Greening Committee and became the "China Ecological Hero" jointly selected by relevant state departments.
Tail:
1, London fog and haze event.
London, England, known as the foggy city, was once again shrouded in dense fog during February 5-8 1952 65438+. During this period, many people suddenly suffered from respiratory diseases, and all the hospitals in London were suddenly crowded with people. In four days, the death toll increased by more than 4000 people compared with the same period of last year. The number of deaths over the age of 45 is about three times that of the usual deaths, and the number of deaths under the age of 1 has increased by 1 times.
Within 1 week of the incident, 9 people died of bronchitis, coronary heart disease, tuberculosis and heart failure. Three times, twice. Four times, five times. Five times, twice. Eight times, the number of people who died of pneumonia, lung cancer, flu and other respiratory diseases doubled than usual. Within two months after the incident, more than 8000 people died.
According to the analysis of this incident, it is believed that this is related to the massive consumption of coal in London at that time. The maximum concentration of dust particles during the event was 4. 46 mg/m3, which is 10 times of normal, and the highest concentration of SO2 is 6 times of normal. Under the specific conditions of dense fog, Fe2O3 in flue gas promoted SO2 oxidation to SO3, forming H2SO4, which condensed on dust and formed acid fog, which became the killer of this incident. ?
2. Japan's four-day city incident.
Shikoku is located in the eastern gulf of Japan. During the period of 1955, more than 10 petrochemical plants were built here. The gas and dust containing sulfur dioxide emitted by chemical plants all day make the clear sky dirty.
196 1 year, respiratory diseases began to appear in this area and spread rapidly. It is reported that chronic bronchitis accounts for 25%, asthma accounts for 30% and emphysema accounts for 15%. 1964, there were three days of smog here, and many asthma patients died. 1967 Some patients committed suicide because of unbearable torture. 1970 has more than 500 patients.
1972, there were 87 asthma patients1person and 87 deaths1person in the city. According to reports, during the incident, the annual emissions of SO2 and dust reached 6.5438+0.3 million tons, the concentration of SO2 in the atmosphere exceeded the standard by 5-6 times, and the smoke was 500 meters thick, which contained harmful gases and metal dust, and they interacted to generate substances such as sulfuric acid, which was the main cause of asthma. ?
3. Water accident in Japan.
There is a small town called Shuicuo in Kyushu Bay in southern Japan, where 40,000 residents live and make a living by fishing. Starting from 1939, the synthetic acetic acid plant of Japan Nitrogen Fertilizer Company began to produce vinyl chloride, and the wastewater from this plant has been discharged into Minamata Bay.
In the process of producing vinyl chloride and vinyl acetate, the company used mercury-containing catalysts, which made the wastewater contain a lot of mercury. This mercury is eaten by fish in the water and converted into toxic methylmercury in fish. After people eat fish, mercury accumulates in the human body, leading to a strange disease: at first, the patient just slurred his speech and faltered, then he developed facial dementia, numbness, deafness and blindness, and finally became insane until he bowed his head and screamed and died. ?
1972 according to the statistics of the environmental department, there are 180 people suffering from wading diseases in Shuicuo town, and more than 50 people died. More than 100 people were found wading in Ayokawa, Xinxian County, and 8 people died. According to the report, the number of patients is far more than that, only the victims in Minamata town, that is, more than 1 10,000 people.
