Objectively speaking, untreated pollutant gas is toxic, but through clean emission treatment of poisonous gas, the toxicity can be reduced or even non-toxic.
The following is a government document issued after citizens complained about some of BOE's factories:
Some residents in Xinzhan District, Hefei City reported on the leadership message board: There is often a foul smell at night near BOE on Xin Bengbu Road. It was sent out from 17:30 to 1 am the next day. Residents of Xinzhan District have repeatedly complained about odor emissions but have not been properly resolved. At present, we want to know where the odor comes from and whether it may have an impact on the body. The factory can handle the emissions in accordance with environmental protection requirements. Why does it happen at night every time? Emissions, please pay attention to the leadership, thank you.
Residents made two similar complaints in January 2020 and June 2020.
First reply:
After investigation, it is found that the company you reported is actually Hefei Xinsheng Optoelectronics Technology Co., Ltd. This company is engaged in manufacturing LCD flat panel display devices, and the production project has been approved by the Ministry of Environmental Protection. The approval was passed and the "three simultaneous" acceptance of environmental protection was completed. The company has installed automatic monitoring facilities for waste gas emissions, and the District Ecological Environment Bureau conducted supervisory testing of the company's unorganized and organized waste gases. The test results showed that the pollutants were discharged in compliance with the standards. In order to further improve the surrounding air quality, the District Ecological Environment Bureau requires the company to ensure the efficient and normal operation of exhaust gas treatment facilities, regularly detect exhaust gas pollutant emission indicators, strictly meet emission standards, and further improve and control exhaust gas pollutant emissions. At present, the company has submitted a plan to improve the standards for exhaust pollutant emissions. In the next step, relevant departments in the district will urge enterprises to carry out planned improvement of exhaust pollutant emission standards in accordance with the plan to further improve air quality.
