Ministry of the Environment released the measurement standard for industrial oil mist

     In order to implement the "Environmental Protection Law of the People's Republic of China", protect the ecological environment, safeguard human health, improve the level of ecological environment management, and standardize the monitoring of ecological environment, the Ministry of Education decided to develop a "fixed pollution source, the determination of soot and oil mist.

Fume Oil fume

     Refers to the oils that are volatilized during food cooking and processing, organic matter and their pyrolysis or cracking products.

Oil mist

     Refers to the mineral oil produced by volatilization in industrial production processes (such as machining, metal material heat treatment, etc.) and its thermal decomposition or cracking.

Oil mist damage to the environment

        Soot refers to the cooking, the oil that is volatilized during processing, the organic matter and its thermal decomposition or cracking. Its main components are animal and vegetable oils and their decomposition products. Oil mist refers to the source, mechanical processing and other processes to produce oil and its lysate, the main component of which is mineral oil. At present, soot and oil mist have become another major pollution problem after noise, exhaust gas and sand dust, and have become one of the hot issues of environmental complaints of the people. Research by relevant departments on PM2.5 in atmospheric aerosols in Beijing shows that the content of organic matter is as high as 30-40%, and the proportion of soot from the catering industry has reached 13-15%, which is significantly higher than that of developed countries. The research results of Wang Yuesi and other researchers of atmospheric physics research of the Chinese Academy of Sciences show that the most important component of organic aerosols emitted by food fume, the proportion of catering fumes in the PM2.5 in the Beijing market is about 13%, and the highest reaches 15%. %. The proportion in the Beijing-Tianjin-Hebei region is about 6%. According to media reports, the current proportion of catering enterprises in Guangzhou accounts for about 14% of atmospheric pollution. The above data show that soot has become an important source of pollution affecting urban air quality. Strengthening pollution control measures to promote oil mist and oil mist is an important measure to improve urban air quality.

       The method for measuring oil mist pollution is also important. The task of monitoring and correcting oil smoke and oil mist pollutants issued by the Environmental Protection Department is revised by the Dalian Environmental Monitoring Center. A standard preparation group is set up to inquire about relevant standards at home and abroad. Market research and development of groping experiments, organization of expert groups to open the discussion, carry out experimental research work, organize experiments, prepare standard consultation drafts and preparation instructions, consult the technical review meeting, and finally improve the standard draft and preparation instructions.
