Recent Major Environmental Pollution Accidents in China

20/kloc-in the first half of 0/5, six sudden environmental incidents occurred in * * * all over our province. According to the classification standard of "National Emergency Plan for Environmental Emergencies", all of them are general environmental emergencies, and they have been properly handled in time. These six incidents are: on March 24th, the fire in the warehouse of Anhui Lishi Electric Power Technology Co., Ltd. caused secondary environmental pollution; On April 16, a fire broke out in the workshop formation process of Anhui Hairong Power Supply Co., Ltd., causing secondary environmental pollution; On April 17, a traffic accident in Lujiang section of Hefei-Tonghua-Huanghua Expressway led to diesel oil leakage, resulting in secondary environmental pollution; On April 27th, a traffic accident in Shun 'an service area of Shanghai-Chongqing Expressway led to hydrochloric acid leakage, which caused secondary environmental pollution. On May 2, the Jiulanghe Bridge on National Highway 320 in Tongling County caused a traffic accident due to sulfuric acid leakage, which caused secondary environmental pollution. On May 8, a traffic accident occurred in Jinzhai section of Hefei-Wuhan Expressway, resulting in styrene leakage and secondary environmental pollution.

20 14 At 4 o'clock on April 23rd, the concentration of ammonia nitrogen at the entry section of Wuhan section of Hanjiang River in Hubei Province exceeded the standard. On 23rd 16: 30, Wuhan Baihezui Waterworks, Yushidun Waterworks and Guomian Waterworks stopped supplying water one after another because the ammonia nitrogen in the factory water exceeded the standard.

On September 1 1, 2002, a lead-zinc tailings dam in the upper reaches of Duojie Village, Duyun Ancient Town, Guizhou Province collapsed, and thousands of cubic meters of slag poured down from the cliff and flowed into Fanjiahe River at the foot of the mountain. Trees soaked in tailings along the coast died, and fertile fields were buried by slag. The viscous mud mixed by powdered lead-zinc tailings and river water is directly discharged into Qingshui River through Fanjiahe River. After the incident, the Qingshui River, more than 20 kilometers downstream, was still turbid, and drinking water for people and animals was once difficult.

Water pollution incident in Nanpanjiang, Yunnan

From June, 5438 to October, 2002, serious water pollution broke out in the upper reaches of Chaishitan River in Nanpanjiang, Yunnan Province, killing hundreds of tons of fish and polluting more than 300 million cubic meters of water in the lower Chaishitan Reservoir. Due to the dense population and concentrated industrial and agricultural production along the Nanpanjiang River, it is one of the more developed areas in Yunnan. This water pollution incident not only caused huge economic losses, but also caused very bad social impact.

In 2003

Sanmenxia Reservoir Releases "One Reservoir Sewage"

In 2003, the industrial sewage discharged by some enterprises in the upper reaches of Sanmenxia Dam and the domestic sewage discharged by towns near the Yellow River increased year by year, resulting in the most serious pollution of the Yellow River. The water discharged from Sanmenxia Reservoir is "soy sauce color", and the water quality has deteriorated to Grade V, becoming a veritable "one reservoir sewage". Although Sanmenxia City is close to the Yellow River, citizens have to spend money to buy mountain spring water from nearby mountains. "Watching the Yellow River buy water to eat" has become a great spectacle in Sanmenxia City.

In 2004

Extraordinary water pollution incident in Tuojiang, Sichuan.

At the end of February and the beginning of March, 2004, the Second Fertilizer Plant of Sichuan Chemical Industry Co., Ltd. discharged a large amount of high-concentration ammonia-nitrogen wastewater into Pi River, a tributary of Tuojiang River, which caused the Tuojiang River to turn yellow and stink, and the ammonia-nitrogen exceeded the standard by 50 times. After the pollution, 500,000 kilograms of cage fish died, and the direct economic loss was about 300 million yuan. Jianyang, Zizhong and Neijiang along the Yangtze River were forced to stop water around, affecting millions of people. The local pure water was snapped up, and the local government mobilized fire trucks from Yibin and Chengdu to deliver water, which still could not meet the daily water consumption of residents. In order to alleviate the disaster, emergency water transfer from Dujiangyan and Sancha Lake diluted 2000 tons of ammonia nitrogen, but it was too late. According to experts' calculation at that time, it will take at least five years to restore the destroyed ecology of Tuojiang River.

Puyang, Henan Province can't drink "safe water"

From June 5438+ 10, 2004, a water pollution incident occurred at the water intake of the Yellow River in Puyang City, Henan Province, which lasted more than four months. The drinking water safety of more than 400 thousand residents in the urban area is threatened, and Puyang city is forced to use the standby underground water source. According to the investigation, since 1997, the water intake of the Yellow River in Puyang City has been polluted for many years, and the urban drinking water source is affected by pollution for about 4 to 5 months every year.

Water pollution incident of Qingyi River in Sichuan

From the end of June, 5438 to February, 2004, some paper-making enterprises secretly discharged a large amount of industrial sewage into Qingyi River in Leshan City, Sichuan Province, resulting in a large number of white bubbles on the water surface, emitting a pungent alkaline smell. Qingyi River was originally the drinking water source of nearly 400,000 people in Leshan City. However, after the water quality has been seriously polluted, due to the increased difficulty in producing qualified drinking water, the surrounding water supply companies are on the verge of stopping production, and the local people are facing a water shortage crisis.

In 2005

Chongqing Qijiang water pollution incident

Since June 5438+1October 3, 2005, the water intake was polluted by the wastewater discharged by Chongqing Huaqiang Chemical Fertilizer Co., Ltd., which caused the water plant to stop supplying water. Nearly 30,000 residents in Daoqiaohe area, Gu 'nan Street, Qijiang, Chongqing were cut off from water for two days, and Qijiang Gear Factory stopped production.

Jiaxing, Zhejiang, suffered from pollution and water shortage crisis.

In mid-March, 2005, various water-saving publicity materials appeared on the streets of Jiaxing, Zhejiang Province, asking residents to wash vegetables with rice washing water, wipe the floor with laundry water, or put bricks in the toilet tank to save water for flushing toilets. The water price of residents in this city has also increased from 1.65 yuan to 1.9 yuan per ton. The survey shows that although Jiaxing is a world-famous "water town" with dense river networks, there is a shortage of available water resources in Jiaxing due to the upstream transit water pollution.

The Yellow River water has become "the harm of agriculture"

In 2005, crops in some areas of the Yellow River Basin were reduced or even not harvested. The reason is that there are many highly polluting industrial enterprises such as energy, heavy chemicals, non-ferrous metals and paper making along the Yellow River from Qinghai to Inner Mongolia, and the wastewater discharge is increasing year by year. A large number of substandard industrial wastewater is directly discharged into the diversion canal, which leads to similar sewage irrigation in some irrigation areas along the Yellow River, and the Yellow River water has become a "agricultural hazard".

Major water pollution incident in Songhua River

On June 5438+065438+1 October 13, 2005, an explosion occurred in the aniline workshop of Shuangbenzene Plant of China Petroleum Jilin Petrochemical Company, killing 5 people, leaving1missing and injuring nearly 70 people. After the explosion, about 100 tons of organic pollutants such as benzene, aniline and nitrobenzene flowed into the Songhua River, causing serious pollution of the river and affecting the lives of millions of residents along the coast. Songyuan City, Jilin Province, and Harbin City, Heilongjiang Province successively stopped water supply for several days. Downstream pollution even threatens the Khabarovsk Krai in Russia, causing serious international negative impact. The incident also exposed the disadvantages of undisclosed information and insufficient crisis handling ability. For example, there have been rumors and panic scenes such as snapping up drinking water in Harbin.

Afterwards, the investigation team of the State Council determined that this was a particularly serious water pollution responsibility incident, and dealt with the person responsible for the accident 12, and Xie Zhenhua, the former director of the State Environmental Protection Administration, resigned. In the past five years, the state has invested a total of 7.84 billion yuan in pollution control funds for the prevention and control of water pollution in the Songhua River Basin.

Cadmium pollution accident in Beijiang, Guangdong Province

In June 5438+February 65438+May 2005, serious cadmium pollution occurred in Shaoguan section of Beijiang River, Guangdong Province, and the cadmium concentration in Gao Qiao section exceeded the standard by more than 12 times. Beijiang River is one of the three major tributaries of the Pearl River, and it is also an important drinking water source for Guangdong cities. Because Shaoguan is located in the upper reaches of Beijiang River, the pollution directly threatens the drinking water safety of nearly 10 million people downstream and the normal water use of thousands of enterprises, and the tap water supply in some cities has stopped. After investigation, the accident was caused by the illegal discharge of cadmium-containing wastewater in Shaoguan Smelter during equipment maintenance.

In 2006

Dead fish incident in Baiyangdian, Hebei Province

In February and March of 2006, a large area of dead fish appeared in Baiyangdian Lake, the largest freshwater lake in North China, which is known as the "Pearl of North China". The investigation results show that the main cause of fish death is serious water pollution and low dissolved oxygen in the water, which eventually leads to fish suffocation and death. According to statistics, 96,000 mu of water body belonging to Renqiu City, Hebei Province is polluted, and the water body is black and smelly. All the fish cultured in cages die, and a large number of dead wild fish float in the lake, and some aquatic plants die black.

Pollution incident of Mangniu River in Jilin Province

On August 2, 2006, KLOC-0, Jilin Environmental Protection Bureau received a report from the masses that chemical pollution occurred near Mangniu River. After field investigation, it was found that some water quality was red with a little foam, and the pollutant was dimethylaniline, forming a pollution zone about 5 kilometers long. After investigation, the accident was caused by artificial discharge of chemical wastewater into Mangniu River by Jilin Changbai Mountain Fine Chemical Co., Ltd..

Arsenic pollution incident in Yueyang, Hunan Province

On September 8, 2006, a water pollution incident occurred in Xinqiang River, a drinking water source in Yueyang County, Hunan Province. The arsenic exceeds the standard by about 10 times, and the drinking water safety of 80,000 residents is threatened. After investigation, the culprit of this pollution is three chemical plants in the upstream. Due to the daily discharge of industrial sewage, a large number of high-concentration arsenic-containing wastewater flows into Xinqiang River.

Major environmental pollution accident in Luzhou Power Plant, Sichuan Province

In June 2006, 5438+065438+1October, 65438+May, the construction unit of Sichuan Luzhou Chuannan Power Plant began to install and debug the fuel system before the sewage facilities were completed, resulting in diesel oil leaking into the cooling water pipeline and being discharged into the Yangtze River. On the same day, the company reported that the diesel oil entering the Yangtze River was 0.38 tons. Under the supervision of the environmental protection department, the diesel oil entering the Yangtze River the next day was 16.945 tons. This accident caused the urban area of Luzhou City to stop water supply and enter Chongqing to form cross-border pollution.

Afterwards, the State Environmental Protection Administration decided that this was a major environmental pollution incident. Luzhou Chuannan Power Generation Co., Ltd. was fined 200,000 yuan, and the relevant responsible persons of the company were punished by deducting bonuses and revoking their posts. Before May 15, 2007, Sichuan Environmental Protection Bureau suspended the approval of all new projects in Huzhou except pollution control projects.

In 2007

Cyanobacteria Crisis in Taihu Lake, Chaohu Lake and Dianchi Lake

Since May 29, 2007, the tap water quality of a large number of citizens in Wuxi City, Jiangsu Province has suddenly changed, accompanied by an unpleasant smell, which makes it impossible to drink normally. The reason is that a large area of cyanobacteria has appeared in Taihu Lake as a local drinking water source. This "frequent visitor" who invades Taihu Lake every year has come earlier and more fiercely this year. Small blue-green algae disrupted the normal life of millions of Wuxi citizens overnight, and the pure water in supermarkets was snapped up, and the price of bottled pure water in street retail also soared.

In June, cyanobacteria also appeared in Chaohu Lake and Dianchi Lake. A large area of cyanobacteria about 5 square kilometers appeared in the western half of Chaohu Lake in Anhui Province. With the continuous high temperature, cyanobacteria also appeared in the eastern half of Chaohu Lake, threatening the local drinking water safety. Dianchi Lake in Kunming, Yunnan Province is also sweltering for several days, and cyanobacteria multiply in large numbers. On the bank of Dianchi ridge, the lake is green paint, accompanied by bursts of stench.

Jiangsu Shuyang water pollution incident

At 3 pm on July 2, 2007, the surface water plant in Shuyang County, Jiangsu Province found that in a short period of time, a large amount of sewage invaded the water intake of the waterworks located in Huaishuhe River, and the water flow showed obvious odor. After testing, the ammonia nitrogen content in the water of the water intake is about 28 mg per liter, which far exceeds the national water quality standard of the water intake. Because the polluted water could not meet the drinking water standard after treatment, the urban water supply system was forced to shut down, affecting 200 thousand people's water use, and the whole Shuyang County was cut off for more than 40 hours.

the year of 2008

Poisonous water incident in Baishui village, Guangzhou

On March 2, 2008, 4 1 villager in Baisha Village, Zhong Luotan Town, Baiyun District, Guangzhou, suffered from vomiting, chest tightness, black fingers and cramps after eating at home or in a restaurant, and were sent to hospital for treatment. According to the investigation, the cause of this pollution is that a small private factory in Baisha village improperly used nitrite, which polluted the well dug by the factory without authorization, and illegally connected the pumping pipe and tap water pipe of the well without permission, resulting in tap water pollution.

Arsenic pollution incident in Yangzonghai, Yunnan

Since June 2008, the arsenic concentration in Yangzonghai, one of the nine plateau lakes in Yunnan, has seriously exceeded the drinking water safety standard, directly endangering the drinking water safety of 20,000 people. From July 8, people and enterprises around the lake stopped using water as drinking water. On September 12, the Yunnan provincial government decided to implement the "three prohibitions" on Yangzonghai, that is, no drinking, no swimming and no fishing for aquatic products. And decided to take measures to investigate and deal with polluting enterprises, start comprehensive pollution control measures, and strive to restore the water quality of Yangzonghai to normal in about three years.

Because of this pollution incident, Yunnan Province imposed administrative accountability on 26 government workers, of whom 12 were dismissed. In order to strengthen environmental law enforcement, Kunming Public Security Bureau has set up an environmental protection sub-bureau, which is the first time in China.

In 2009

Water pollution incident in Yancheng, Jiangsu

On February 20, 2009, because the tap water source was polluted by phenolic compounds, Yancheng City, Jiangsu Province cut off water for nearly 67 hours, affecting the lives of 200,000 citizens, accounting for two-fifths of the city's urban population. According to the investigation, Yancheng Biaoxin Chemical Plant, which was rated as a local model enterprise, created this pollution incident. In order to reduce the cost of pollution control, the factory secretly discharged 30 tons of chemical wastewater in rainy days, and finally polluted the water source. Afterwards, two persons in charge of the factory were sentenced to 10 and 6 years' imprisonment respectively for "throwing dangerous substances", which is the first time that China has made criminal punishment for environmental pollution incidents on this charge.

Arsenic pollution incident in Yinan, Shandong Province

In April 2009, yinan county Yixin Chemical Co., Ltd. illegally produced arsanilic acid without the approval of relevant procedures, and stored a large amount of arsenic-containing toxic wastewater produced in the production process in a deliberately hidden sewage pool. Late at night on July 20th and 23rd, the company used local rainfall to pump waste water with arsenic content exceeding 27,254 times into the Su River, causing serious water pollution. Afterwards, the three responsible persons involved in the case were sentenced respectively, and were sentenced to * * * to compensate the national economic loss of 37 1.4 million yuan.

Collapse accident of Hanyin tailings pond in Shaanxi Province

Danger has seriously polluted the Niqing River near the tailings pond, and seriously threatened the water quality of Guanyinhe Reservoir, the main source of tap water in the old city of Hanyin County.

Cadmium pollution incident in Liuyang, Hunan Province

In 2003, Shuangqiao Village, Shitou Town, Liuyang City, Hunan Province introduced Changsha Xianghe Chemical Plant through attracting investment. In April of the following year, the factory built 1 indium smelting production line without approval, and discharged industrial waste for a long time, which caused a large area of cadmium pollution in the surrounding area and led to a large area of vegetation dying. Some villagers experienced dizziness, chest tightness, joint pain and other symptoms due to excessive cadmium in their bodies, and two villagers died. On July 29th and 30th, 2009, thousands of local villagers blocked the town government and police station because of unbearable pollution. Afterwards, the heads of enterprises and government officials related to pollution were investigated and suspended.

In many places, children's blood lead exceeds the standard.

In August 2009, among the 10 16 children tested in Fengxiang County, Shaanxi Province, * * * found that 85 1 children's blood lead exceeded the standard, which triggered a vicious group incident. Subsequently, the blood lead of 1.354 children in Wugang city, Hunan province was found to exceed the standard, and that of/kloc-0 children in Shanghang county, Fujian province was found to exceed the standard. 65438+In late February, dozens of children in Qingyuan City, Guangdong Province were also collectively found to have lead poisoning. After investigation, these lead poisoning incidents are all related to the sewage discharge of local enterprises, and the problem of heavy metal pollution has attracted great attention from relevant departments.

"Hometown of Nonferrous Metals" is in urgent need of drinking water.

In 2009, a survey report revealed that in Hunan, known as the "hometown of non-ferrous metals", mining, smelting, chemical and other enterprises were mostly distributed in the Xiangjiang River Basin, resulting in serious heavy metal pollution. For many years, the emissions of mercury, cadmium, chromium and lead in Hunan ranked first in China, and the emissions of arsenic, sulfur dioxide and chemical oxygen demand (COD) ranked first in China. Fish in Xiangjiang River basin has been greatly reduced, thousands of acres of farmland can not be cultivated, a considerable area of fish, grain and vegetables can not be eaten, and the drinking water safety of 40 million people is threatened.

20 10 year

Leakage accident of copper acid water in Zijin mining industry

20 10 On July 3, Fujian Zijin Mining Group Co., Ltd., the copper acid water leaked, and 9 100 cubic meters of sewage flowed into the Tingjiang River along the spillway culvert, resulting in serious pollution in some sections of the Tingjiang River, and millions of kilograms of fish cultured in cages by local fishermen died, resulting in a direct economic loss of 3187100,000 yuan. However, Zijin Mining did not make an announcement until 9 days after it concealed the pollution accident, and sewage infiltration occurred again on July 16 due to poor emergency response. On September 2 1, a dam-break accident occurred in the Gaoqiling tailings pond of Yin Yan tin mine of Maoming Xinyi Zijin Mining Co., Ltd., causing heavy casualties and property losses.

After the incident, many local officials were suspended for inspection or ordered to resign, and the heads of relevant enterprises were criminally detained. 20 10, 10, Fujian Environmental Protection Bureau imposed an administrative penalty of 95 13000 yuan on Zijin Mining, setting a record for fines imposed on polluting enterprises.

Dalian Xingang crude oil spill incident

20 10, 16 On the afternoon of July, a 300,000-ton Liberian oil tanker was unloading additional additives, which led to the explosion of the land oil pipeline and the leakage of five nearby oil tanks with the same volume of 6,543,800 cubic meters. It was not until July 22 that the leak was basically blocked. It is estimated that the accident polluted at least 50 square kilometers of water nearby.

Songhua River Chemical Barrel Incident

On July 28th, 20 10, warehouses of two chemical enterprises in Jilin Province were destroyed by floods, and 7 138 barrels were washed into Wende River and then entered Songhua River. The main raw materials in the barrel are trimethylchlorosilane and hexamethyldisilazane, and the pollution zone is 5 kilometers long. In order to prevent the crisis from expanding, tens of thousands of people were dispatched along the coast to intercept it, and the urban water supply pipeline was cut off, almost a replica of the explosion of Jilin Petrochemical five years ago.

Chromium waste in Henan Province accumulates into urban cancer

20 10,10/0 On October 25th, the media reported that a number of chemical enterprises were built in Henan Province from 1950s to 1980s and 1990s, leaving more than 6 million tons of waste chromium slag, which was stored in piles around more than 20 cities and became an "urban cancer". Chromium slag contains carcinogen calcium chromate and toxic substance hexavalent chromium. Because most of these chromium slag piles have no rain-proof and seepage-proof measures, after decades of rain and infiltration, they have become pollution diffusion sources that permanently destroy groundwater and farmland.

20 1 1 year

Incidents of blood lead exceeding the standard occur from time to time.

Blood lead exceeded the standard in 2009 and 20 10, and it continued to spread in 20 12. In June 5438+10, 228 children in Xinshan Community, Gaohe Town, Huaining County, Anhui Province had blood lead exceeding the standard.

In May, Guangdong Zijin Three-dimensional Battery Co., Ltd. was exposed to lead exceeding the standard 136 people, of whom 59 people met the criteria for judging lead poisoning; In September, 25 children in Kangqiao area of Shanghai were found to have excessive blood lead.

The pollution sources that lead to the above blood lead exceeding the standard are almost all battery enterprises. The Ministry of Environmental Protection inspected 388 lead-acid battery enterprises in March of 20 1 1, and found that most small and medium-sized enterprises had various environmental violations, so it focused on rectifying lead-acid battery enterprises. Among them, due to the blood lead incident in Deqing, Huzhou was completely restricted by the region.

Oil spill accident in Penglai Oilfield in Bohai Sea

20 1 1 On June 4th, 2008, an oil spill occurred in Penglai 19-3 oilfield, which was jointly operated by CNOOC and ConocoPhillips. As of February 29th, 12, this accident has polluted 6,200 square kilometers of the Bohai Sea, accounting for about 7% of the Bohai Sea area, and the water quality in most sea areas has been reduced from the original Grade I to Grade IV, which has affected the ecological environment of the affected areas.

After the accident, CNOOC and ConocoPhillips were criticized by public opinion because of incomplete information disclosure, shirking responsibility and poor disposal. The claim was difficult until the following year. Among them, the State Oceanic Administration announced on April 27th, 20 12 that ConocoPhillips and CNOOC would pay a total compensation of168.3 billion yuan, setting a record for China's ecological claims.

Harbin Pharmaceutical Factory is trapped in the "pollution gate"

20 1 1 On June 5, 2008, CCTV exposed the long-term illegal sewage discharge of Harbin Pharmaceutical Group Pharmaceutical General Factory: the exhaust emissions around the factory area seriously exceeded the standard, and the odor was unpleasant; Some sewage treatment facilities have not been fully started due to maintenance, and sewage is directly discharged into the river, resulting in discoloration of the river; A large amount of waste residue is either burned anywhere or dumped directly on the edge of the river ditch. The test results of air quality in the area adjacent to the pharmaceutical factory show that hydrogen sulfide gas exceeds the standard 1 150 times, and ammonia gas exceeds the standard by 20 times. This kind of "land, water and air" three-dimensional sewage discharge is not a day's work. The surrounding residents have complained for many years, but Harbin Pharmaceutical Factory has always been reluctant to invest to solve the problem.
