According to reports, China is a big country for the production and use of pesticides. The majority of POPs production enterprises were built in the 1960s and 1970s. They have poor production equipment, poor technology, and no pollution control facilities, causing serious pollution to the surrounding environment. After the ban on the production of some POPs chemicals in the 1980s, most companies did not clean up production facilities and sites. The toxic and hazardous wastes that were cleaned up by individual companies were simply stacked outside the plant area. Most of the storage sites did not have protective measures, resulting in the generation of surrounding soil and groundwater. Serious pollution. In addition, the non-standard piling of waste residue and fly ash containing waste pesticides and two dioxin also exacerbated site pollution. With the urban economic development and industrial and product structure adjustment, especially after the end of the exemption period next year, a large number of POPs production and use enterprises will be gradually shut down or transferred. These POPs-contaminated production sites have become potential sources of pollution and have a great environmental risk.
Zhuang Guotai, director of the office of the Foreign Economic Cooperation Leading Group Office of the Ministry of Environmental Protection, pointed out that environmental risk management of POPs contaminated sites is a prominent environmental issue related to people's livelihood. The Ministry of Environmental Protection attaches great importance to this. Zhuang Guotai said that he hopes that international organizations and bilateral agencies will pay more attention to and pay attention to the problem of POPs contaminated sites. Together with the Chinese government, they will discuss and work together to solve the problem of POPs contaminated sites and provide financial, technical and management support. In addition, relevant domestic experts must also provide strong technical support.
The management of POPs contaminated sites in China cannot be delayed
China's management in the field of contaminated sites has only just begun. Policies, standards, technologies, and funding mechanisms are all left blank, and regulatory capacity and public awareness need to be improved. The initiation of POPs (Persistent Organic Pollutants) contaminated site management work has become an urgent task. This is what the reporter learned from the International Symposium on Contaminated Sites of POPs held in China from May 23 to 24.
