2065 438+00-2065 438+04 Names of Six Environmental Pollution Events in China

In the past 20 13, China suffered serious environmental pollution again. How to maintain a pure land for future generations has become an important issue for modern people and the government. From the PX project in Dalian to Shifang in Sichuan, people are using their own efforts to protect their homes. Even so, there are still many environmental problems that are inevitable. Today, let's take a look at the big pollution problem that happened in the past 20 13.

First, smog ranks first. 20 13 six major environmental problems in China

In 20 13, "smog" became the key word of the year. In June 5438+10, four smog processes enveloped 30 provinces (autonomous regions and municipalities). In Beijing, only five days are not foggy. It is reported that less than 65,438+0% of the 500 largest cities in China meet the air quality standards recommended by the World Health Organization. Meanwhile, among the 65,438+00 most polluted cities in the world, 7 are in China.

20 13 China suffered the worst air pollution in history.

The persistent haze has enveloped more than 65,438+00 provinces in China. Hazy weather, a large number of harmful substances such as dust particles and smoke particles floating in the air will cause harm to the human respiratory tract. There are a lot of particles, dust, pollutants and viruses floating in the air. Once inhaled by the human body, it will stimulate and destroy the respiratory mucosa, dry the nasal cavity, destroy the defense ability of the respiratory mucosa, and bacteria will enter the respiratory tract, which is easy to cause upper respiratory tract infection.

If you think that pollution is only a characteristic of the north, you are wrong. At the end of 20 13, central China, such as Shanghai and Nanjing, suffered the most, and the PM2.5 data in many places in Shanghai exceeded 500. In addition, Guangdong and even Hainan also suffered from smog. It is no exaggeration to say that smog has become the first word of environmental pollution in China.

Second, Shanghai Songjiang dead pig incident

20 13, a large number of dead pigs floated in Songjiang section of Huangpu River in Shanghai. On March 20th,13, 10 learned the latest progress from the Shanghai Municipal Commission of Agriculture and the relevant departments in Songjiang District: the number of dead pigs salvaged exceeded 1200. These dead pigs are basically from the upper reaches of Shanghai. Shanghai is stepping up coordination with the surrounding areas in the upper reaches of Huangpu River to investigate the source of dead pigs, so as to stop the irregular handling of dead pigs from the source. According to the Shanghai Water Affairs Bureau, the local tap water quality in Songjiang is "normal" and meets relevant standards. The number of dead pigs in Huangpu River incident has increased again. Up to March 20th, a total of floating dead pigs 10395 were salvaged in the waters of relevant areas in Shanghai.

From March 2065438 to March 2003, a large number of dead pigs floated in Songjiang section of Huangpu River in Shanghai.

According to the daily report of the Shanghai Municipal Government, the water quality is basically normal after strict testing so far. This release caused many questions: "There are thousands or even tens of thousands of dead pigs floating on the Huangpu River, but the water quality is basically stable? Is it possible? "

It is understood that there are several major water sources in Shanghai, namely, the upper reaches of Huangpu River, Qingcaosha in the Yangtze River Estuary and Chen Xing in the Yangtze River Estuary, and the Dongfeng Xisha in Chongming is under construction. The water area where the dead pigs are concentrated this time is the water source of the upper reaches of Huangpu River.

It mainly supplies water to Songjiang, Jinshan, Minhang and Fengxian, involving 6 water intakes and 9 water plants of water supply enterprises in 4 districts, with a total water supply scale of 24 1 10,000 tons/day, accounting for about 22% of the city's scale; Qingcaosha water source is responsible for 70% of Shanghai's water supply, which is safe and reliable. The drinking water in the central city and other suburban counties has nothing to do with the water source involved in this incident.

According to the national standards, Shanghai not only tested nine routine water quality indicators, such as turbidity, color, smell and visible matter, but also added microbial indicators such as porcine circovirus to the water quality monitoring indicators, and added indicators such as Streptococcus suis, Salmonella, Escherichia coli O 157 and thermotolerant coliforms to the factory water. The test results show that 9 routine indicators meet the national standards, and the total coliforms and heat-resistant coliforms are "not detected".

3. The villagers in Henan "Sewage Irrigated Wheat Field" replied with a smile: It's all sold to you.

Henan Xinxiang paper mill used sewage to irrigate wheat fields, and was asked by an interview: "Do you dare to eat the wheat watered by this water?" The villagers' answer was speechless: "(Hehe) I sold it to you."

A paper mill in Xinxiang City, Henan Province polluted the wheat field by illegal sewage discharge. The local government has carried out field measurements on the contaminated wheat fields to ensure that these wheat will not flow into the market.

In a recent unannounced visit to wading enterprises in some areas, the Environmental Protection Department of Henan Province found that a paper mill in Xinxiang, Henan Province illegally used some untreated wastewater directly to irrigate wheat fields, causing environmental pollution. At present, this enterprise has been ordered to shut down and rectify. The local government also measured the contaminated wheat fields on the spot to ensure that the wheat was harvested separately and did not flow into the market.

On March 18 and 19, law enforcement officers of the Supervision Corps of Henan Provincial Environmental Protection Department went to Xinxiang, Linying and Jiyuan to make unannounced visits to water-related sewage enterprises. At Dongfeng Paper Mill in Xiaokuai Village, Dakuai Town, Fengquan District, Xinxiang City, law enforcement officers found that some untreated papermaking wastewater was directly discharged into wheat fields. According to law enforcement officials, papermaking wastewater belongs to industrial wastewater and the pollution is very serious.

The factory signed an agreement with the local village committee on July 20 12 to irrigate farmland with untreated papermaking wastewater, which is a serious environmental violation.

Xinxiang City has carried out a dragnet investigation of the city's wading enterprises, and sent a special team to Fengquan District to order Dongfeng Paper Mill to shut down and rectify, and impose penalties according to laws and regulations. The Quanfeng district government also conducted field measurements on the sewage flowing into the wheat fields, implemented it in households and registered it to ensure that the sewage flowed into the plots, and the wheat was harvested separately and did not flow into the market.

Four, Qingdao oil pipeline explosion

20 1 165438 20031at 3: 00 am on October 22nd, the oil pipeline of Weifang Branch of Sinopec Oil Storage and Transportation Company broke at the intersection of Qinhuangdao Road and Zhaitangdao Road in Huangdao District. After the accident was discovered, the oil transportation was closed around 3: 00+05, and the pavement of Zhaitang Road Street was polluted by crude oil, and some crude oil entered along the rainwater pipeline. Huangdao District immediately organized the deployment of two oil booms on the sea surface. During the disposal process, at about 10: 30 in the morning, the intersection of Coastal River Road and Zhaitangdao Road in Huangdao District exploded, and at the same time, the sea surface polluted by oil pollution at the estuary exploded.

According to the investigation report, on October 22nd, 2003165438, crude oil leaked from Sinopec Donghuang oil pipeline in Qingdao, Shandong Province entered the municipal drainage culvert, and oil and gas accumulated in the culvert to form a closed space, accompanied by sparks and explosion. The direct cause of the accident is that the pipeline at the intersection of the oil pipeline and the drainage culvert is corroded and thinned, the pipeline is broken, the crude oil leaks, flows into the drainage culvert and rushes back to the road surface. After the crude oil leaked, the on-site disposal personnel used hydraulic hammer to punch and break the culvert cover plate, which produced impact sparks and caused oil and gas explosion in the culvert.

Because it takes more than 8 hours from the leakage of crude oil to the explosion, the leaked crude oil and its mixed gas spread, spread and accumulate in the drainage culvert, which eventually led to a large-scale continuous explosion. The accident caused 62 deaths, 136 injuries, and the direct economic loss was 75 1.72 million yuan.

Five, Hebei Iron and Steel Company air pollution

How to maintain the first-class air quality has become the focus of government work. Obviously, Shougang's moving out of Beijing cannot be the key to solving the problem. Because of its geographical location, Hebei has become the top priority in controlling air and water pollution.

On May 16, the relevant person in charge of the Ministry of Environmental Protection said that the Ministry of Environmental Protection had completed the verification of the total emission reduction of major pollutants in all provinces, autonomous regions, municipalities directly under the Central Government and eight central enterprises in 20 12, and inspected the implementation of the total emission reduction target of major pollutants in the Twelfth Five-Year Plan. After verification, there are still a few places and enterprises with outstanding emission reduction problems.

Hebei Iron and Steel Group and other 15 enterprises with abnormal desulfurization facilities and fraudulent monitoring data were listed and supervised, and ordered to make rectification within a time limit and recover sulfur dioxide sewage charges. Enjoy the desulfurization price subsidies, deducted from the desulfurization price according to regulations, and give economic penalties.

The recent covert investigation organized by the Ministry of Environmental Protection found that the rectification scheme of some iron and steel enterprises in Hebei Province was not perfect, and the discharge of main pollutants after rectification could not meet the Emission Standard of Air Pollutants for Iron and Steel Industry in Hebei Province.

In this regard, Hebei Province will once again carry out dragnet investigation on iron and steel enterprises, especially focusing on the abnormal operation of desulfurization facilities and the falsification of online monitoring data, and issue rectification tasks within a time limit for iron and steel enterprises with environmental problems, and urge them to formulate sound rectification plans, strictly review the rectification plans, and organize their implementation after expert argumentation to ensure that iron and steel enterprises are qualified for rectification within a time limit.

6. Water pollution of China Petroleum Changqing Oilfield Company

On June 20th, it was reported that the sewage from Su 5- 15-27AH gas well in Changqing Oilfield of China Petroleum was directly discharged into Erzi Knohl Lake, resulting in the sudden death of hundreds of local livestock. Narisu, mayor of Garutu town, said: "After collecting the evidence of livestock deaths, we will contact polluting enterprises."

After the pollution accident, Zhao, a researcher of china environmental science Research Institute, went to the local area to investigate. Zhao told this reporter that during the inspection, it was found that "on the tens of thousands of acres of grasslands in Wushen Banner and Otog Banner of Ordos, water sources and their vegetation are showing signs of pollution, a large number of sheep died and obvious diseases appeared, and groundwater was threatened. Some herders have reported that their bodies are beginning to feel uncomfortable. "

A statement provided by the government of Galutu Town about the livestock death caused by lake water pollution reflected by the herdsmen of Salentu Gacha, Galutu Town, Uxin Banner, Inner Mongolia, said that after the pollution incident, "relevant departments have filed a case and imposed a fine of 50,000 yuan on the Safety, Environmental Protection and Quality Supervision and Inspection Institute of PetroChina Qing Chuan Drilling Engineering Co., Ltd.".

After coordination, the polluting enterprises are "willing to help 0/5 herdsmen around the lake/KLOC-0, with a subsidy of * * * 580,000 yuan", and each dead sheep will be compensated 1 10,000 yuan.

Extended data

Causes of environmental pollution

The concentration and toxicity of pollutants will naturally decrease, which is called environmental self-purification. If the discharged soil pollution exceeds the self-purification capacity of the environment, the environmental quality will change adversely, endangering human health and survival, which will lead to environmental pollution. Environmental pollution will reduce biological yield and aggravate environmental damage.
