In fact, in June 2019, the Ministry of Ecology and Environment issued a \"Standard for Controlling Unorganized Emissions of Volatile Organic Compounds,\" which sets requirements regarding the storage, transfer, and transportation of VOCs, as well as various industrial processes; this standard came into effect on July 1, 2019 ； At the beginning of 2018, our country also issued the \"Monitoring Plan for Volatile Organic Compounds in Ambient Air in Key Areas for 2018\", which specified the monitoring tasks for 4 municipalities directly under the Central Government, 15 provincial capitals and cities designated as such, as well as 59 prefecture-level cities. The introduction of a series of documents fully demonstrates China’s emphasis on VOCs emissions. VOCs are important precursors for the formation of fine particulate matter (PM2.5) and ozone (O3). Unlike traditional air pollutants, VOCs are volatile; therefore, any process involving the storage, transportation, mixing, stirring, cleaning, coating, drying, or other handling of substances containing VOCs can result in the emission of these compounds. Meanwhile, according to the \"2018 Monitoring Plan for Volatile Organic Compounds in Ambient Air in Key Areas\" issued in China, municipalities directly under the Central Government, provincial capitals, and cities designated as separate planning units are required to monitor a total of 117 compounds, while cities at the prefecture level need to monitor 70 compounds; as a result, the monitoring of VOCs becomes even more complex. To ensure the smooth monitoring of VOCs, achieve the monitoring objectives, and enhance the scientificity, relevance, and effectiveness of measures to control volatile organic compounds (VOCs), the \"Comprehensive Control Plan for Volatile Organic Compounds in Key Industries\" identifies key control tasks for six industries: the petrochemical industry, the chemical industry, industrial painting, the packaging and printing industry, oil storage, transportation, and sales, as well as industrial parks and clusters. This will further drive the expansion of the VOCs monitoring market. Some analysts say that driven by strong policy support, the VOCs control market is set to experience explosive growth, with its scale expected to exceed 150 billion yuan. Currently, VOCS online monitoring systems are divided into two types: one is for the detection of organized waste gases, which refers to the collection of waste gases emitted through chimneys. Another type is unorganized exhaust gas monitoring. Unorganized exhaust gas monitoring refers to testing in the outdoor environment, that is, testing of exhaust gases in factory areas. According to the reference methods outlined by USEPA, at least four different instrument principles can be employed: Flame Ionization (FID) ； Catalytic oxidation or combustion method ； Infrared absorption method (IR or NDIR) ； Photoionization (PID) involves instruments such as gas chromatography analyzers and hydrogen flame ionization detectors. Given the increasing focus on VOCs and the rapid growth of the market, VOCs are set to become a significant segment of the environmental monitoring industry; as a result, many companies have already begun to focus on this area. In 2018, Shimadzu introduced the \"Detection Method for Volatile Organic Compounds in Ambient Air\", utilizing the high-performance GCMS-QP2020 and GC-2010Pro models in combination with well-known thermal desorption instruments and atmospheric pre-concentration devices available on the market. This solution helped environmental monitoring professionals quickly understand the patterns of pollutant changes in the environment, thereby enhancing Shimadzu’s influence in this industry. To cut into the \"big pie\" and win the market, research and development of instruments are essential. In Shaanxi Province, in order to better monitor VOCs and identify pollution sources, the Xixian New Area has introduced high-temporal and spatial VOCs mobile monitoring vehicles. Equipped with advanced onboard time-of-flight mass spectrometers for volatile organic compounds, a vehicle-based atmospheric sampling system, and a vehicle-mounted satellite positioning system, this mobile monitoring vehicle is capable of analyzing more than 300 types of organic pollutants, including benzenes, alkanes, and alkenes, while in motion. As technology continues to advance, monitoring instruments will also become more portable. In addition to the 6 industries listed this time, the \"Comprehensive Management Plan for Volatile Organic Compounds in Key Industries\" also states that by the end of June 2020, efforts will be made to establish emission standards for air pollutants in industries such as pesticides, automotive painting, container manufacturing, packaging and printing, furniture manufacturing, and the electronics industry. At the same time, standards for VOCs monitoring and analysis methods, as well as technical requirements for monitoring instruments, will be developed to correspond to these emission standards. In the future, VOCs monitoring and control will extend to more industries. Environmental monitoring companies must take responsibility and help with the control of VOCs.
