What is VOC pollution
The air monitoring system detects air pollution. We have heard a lot of air pollution. For example, the well-known smog is caused by PM2.5 particulate matter. I often hear voc pollution, so what exactly is voc?
voc is an acronym for volatile organic compounds. The translation is volatile organic compounds. voc is an air pollutant, that is, a volatile organic substance. The electronic equipment we use every day. If the temperature is high, some semi-volatile organic compounds SVOC will be volatilized. Part of the voc whose vaporization point is above 40 degrees will be released quickly.
Definition of voc
The US Federal Environmental Protection Agency's definition of voc. Volatile organic compounds are except for carbon monoxide, carbon dioxide, carbonic acid, metal carbides, metal carbonates and ammonium carbonate. Any carbon compound that participates in atmospheric photochemical reactions.
The World Health Organization's definition of "total volatile organic compounds". The general term for volatile organic compounds with a melting point lower than room temperature and a boiling point between 50-260°C.
The harm of voc
Voc acts as an air pollutant. First of all, the smell is unpleasant, which will harm the human respiratory system. Secondly, it will cause damage to the human central nervous system and decrease in memory. There are the following carcinogenic chemicals in vocs, such as benzene and benzene series.
The voc's monitoring equipment is varied. Portable volatile organic compound VOC gas detector that can be carried with you. There are also volatile organic compounds monitoring equipment suitable for industrial areas. Both can help people to better monitor the voc.
The voc online monitoring system can store real-time data. The real-time data warehouse system mainly realizes the real-time storage of measurement data generated by all VOC monitoring points of campus enterprises in the monitoring platform data storage center.
Voc online monitoring system data storage. The original monitoring data will all be stored in the distributed file system of the monitoring platform to store a large amount of unstructured data. In order to meet and adapt to the different needs of data volume, data characteristics and query processing. Some are stored in relational databases.
