20 18 causes of pollution sources in changzhou foreign languages school.

20 18 causes of pollution sources in changzhou foreign languages school.

The root of all this lies in the original site of the chemical plant across the street from the school. Because of the environmental pollution caused by land restoration, the school "at least 493 junior high school students are in different health", and pollutants in non-urban air quality standards were detected in the groundwater and air of the school.

265438+20 th Century Business Herald reporter saw at the scene that many flowers and trees were planted in the original plot of the chemical plant, and an excavator was working. The doorman said that the city and district leaders have been here many times and asked not to close the construction site.

On April 18, the Ministry of Education made a statement on the pollution incident in Changzhou's foreign schools, and launched a special mechanism for major emergencies. The state inspector took the lead in rushing to Changzhou for special supervision, and announced the situation in time. Members of the investigation team entrusted by the Ministry of Environmental Protection and Jiangsu Province have arrived in Changzhou one after another to investigate.

Considering the possible impact of the incident, the Changzhou municipal government has changed the use of the polluted land. In the future, as a livelihood project of park environment and ecology, the government will carry out greening and ecological restoration.

Sequela of "retreat from two to three"

During the period from the Tenth Five-Year Plan to the Eleventh Five-Year Plan, southern Jiangsu and other regions ushered in a round of economic transformation, and cities including Changzhou successively implemented the policy and institutional arrangement of "retreating from two to three", that is, moving or investing in different places, in order to promote the development of service industry and increase the proportion of urban tertiary industry.

This development logic was confirmed by Xu Puqing, president of Changzhou Environmental Science Research Institute. In the previous "retreat two into three", Changzhou became a pilot city for the remediation of polluted land in China. The restoration method was consulted and evaluated by experts from well-known universities in China, such as Nanjing Institute of Soil Science, Chinese Academy of Sciences and Nanjing Institute of Environmental Protection, and the thickness of clay coverage in the contaminated area of this plot was determined by environmental health risk assessment model, which passed the acceptance of experts on February 15, 2005.

In order to further control the environmental risk of contaminated soil and groundwater in the plot, the Design Outline of Plot Environmental Monitoring Scheme was compiled, and a five-year implementation plan was formulated. The air, soil and groundwater monitoring of the plot and its surrounding sensitive targets and the controlled remediation project of groundwater were continuously carried out.

"From the current monitoring data, the ecological hidden danger of this plot is controllable." Xu said that it is unlikely that the new campus in changzhou foreign languages school will be relocated again.

Changzhou foreign languages school (hereinafter referred to as "Changzhou Foreign School") is in the whirlpool of public opinion.

According to the information provided by Changzhou Xinbei District Government to the reporter of 2 1 Century Business Herald, experts have been organized to formulate and implement the emergency treatment plan and soil remediation adjustment plan of the original Changlong plot, and at the same time, the use of the plot has been adjusted from commercial development to greening and supporting facilities, and the environmental protection department has strengthened construction supervision to ensure that similar pollution will not happen again.

The government of Xinbei District stated that it publicly apologized to parents and the society for the odor problem in the land restoration project, promised to improve measures, insisted on openness and transparency, accepted social supervision, answered questions, announced the results as soon as possible, and strived to provide a good production, living and teaching environment for the surrounding areas.

"The school did not find any leukemia cases in the outside news, but there was a student suffering from lymphatic diseases. According to the hospital case report we just got, it started before entering school." Cao Hui, president of changzhou foreign languages school, told the reporter of 2 1 Century Business Herald that the new campus was officially put into use in September of 20 15. In the class closest to the polluted area, there is no abnormality in students' physical condition, only "individual colds".

An eighth-grade boy told 2 1 Century Business Herald that his lymph was swollen in the pungent smell, and now he has basically recovered after treatment.

Local reaction to the objection of ecological restoration

The plot involved in this incident belongs to the original sites of Jiangsu Changlong Chemical Co., Ltd., Changzhou pesticide plant, Changzhou Huada Chemical Factory and Changzhou Changyu Chemical Co., Ltd., with a total area of about 26.2 hectares.

In order to improve the surrounding air quality, Xinbei District started the relocation of chemical enterprises in this plot in May 2009, and completed the relocation of the original Changlong Chemical and other enterprises before June 20 1 1. The project was approved on 20 13, and the restoration project of this plot was formally implemented in March. By 20 15, 12, due to improper protection, the odor emitted during maintenance caused environmental complaints.

This time node coincides with the time point of abnormal skin of Changzhou foreign school students. Cao Hui, president of Changzhou Foreign School, told the reporter of 2 1 Century Business Herald that 65438+February was the most provocative moment, which was also confirmed by the direct feelings of two eighth-grade students interviewed.

Since there are a series of construction environmental protection measures and on-site monitoring, why does the smell spread to hundreds of junior high school students? On April 18, Changzhou City and Xinbei District provided explanations to reporters of 2 1 Century Business Herald on many "unresolved issues".

Aiming at the problems of "large-scale landfill of hazardous waste" and "mismatch of detection points", excavation and detection were carried out under the supervision of East China Supervision Center of the Ministry of Environmental Protection, with cumulative footage154m, and key suspected areas were excavated one by one, with an excavation area of 345m2 and a excavation depth of 6m. A total of 30 kilograms of landfill materials were excavated at the site, including two broken iron drums (one of which contained a small amount of dark brown mucus) and.

"The location of drilling is subject to the location identified by the reporter on the spot." Xu Yuqing emphasized this point.

Cao Hui emphasized that the school water comes from the municipal water supply system, and the groundwater has not been exploited. 200 1 The Standing Committee of Jiangsu Provincial People's Congress passed the Decision on Prohibiting Groundwater Exploitation in Suzhou, Wuxi and Changzhou, which is still in use in southern Jiangsu.

Some parents found "other pollutants" in the indoor air of schools through their own channels. Cao Hui explained that the survey was commissioned by the school and the parents by a third party. Other pollutants entrusted by parents, such as acetone and dichloromethane, have low concentrations and are not the characteristic factors caused by pollution in Chimelong.

From 2065438 to the beginning of February 2006, after the completion of the soil remediation and adjustment project of the original contaminated site of Changlong (Huada and Changyu) Company, Changzhou Institute of Environmental Science conducted a comparative sampling and monitoring of ambient air in Changlong site, Changwai North Gate and the north side of Xinbei District Government (comparison point). The monitoring results showed that there was no obvious difference in the organic matter detected in the three sites.

In the conference room of Changzhou Foreign School, the reporter of 2 1 Century Business Herald saw that the container sealed by the notary office still kept the original three samples.

Regarding the problem that the concentration of chlorobenzene in underground water and soil in Changlong exceeds the standard respectively, the local explanation is that after the relocation in 20 1 1 year, the local environmental protection department organized the site environmental investigation of the plot in time. According to the Dutch Soil and Groundwater Environmental Quality (DIV, 2009) (there is no relevant standard in China at present), the concentration of characteristic pollutants such as chlorobenzene in soil and underground water in some areas of the plot exceeded the standard.

One of the main controversial issues is "whether pesticide ingredients have been considered". In this regard, Xu Puqing told the reporter of 2 1 Century Business Herald that in the first quarter of 20 15, Xinbei District Environmental Protection Bureau monitored the concentrations of volatile organic compounds, semi-volatile organic compounds and odor in the ambient air around Changlong plot, in which volatile organic compounds (VOCs) include 6 1 parameters such as chlorobenzene, benzene and toluene, and semi-volatile organic compounds (SVOC) includes. Finally, only benzene and toluene were detected, and the odor concentration was 12. The other substances were not detected (lower than the detection value), and all monitoring indicators were up to standard.

Why is there a pungent smell spreading in on-site inspection and testing? Li Fei, the head of Changzhou Black Peony Construction Investment Co., Ltd., the construction unit of the land restoration project, explained to the reporter of 2 1 Century Business Herald that the dug pollutants were provided to the cement plant and burned according to the disposal process, but the cement plant was in the "de-capacity period", resulting in insufficient start-up, and the pollutants were not transported to the cement plant in time, but piled up on the spot after digging, but the treatment method was "different from complete sealing", so considering that the cement plant may need it at any time, it is not.

According to an interview with the reporter of 265438+20th Century Business Herald, both the statements of Changzhou City and Xinbei District and the reply of the headmaster of Changzhou Foreign School explained that the trigger of this incident was "caused by land excavation and peculiar smell".
