Description

technical field [0001] The invention relates to the technical field of air quality monitoring, in particular to an online navigation monitoring system and analysis method for volatile organic compounds. Background technique [0002] Volatile Organic Compounds (Volatile Organic Compounds, VOC) refers to the kind of volatile organic compounds that will cause harm. The main components of VOC are: hydrocarbons, halogenated hydrocarbons, oxygen hydrocarbons and nitrogen hydrocarbons, which include: benzene series Chemicals, organic chlorides, freon series, organic ketones, amines, alcohols, ethers, esters, acids and petroleum hydrocarbons, etc., have a huge impact on human health. When VOC reaches a certain concentration, people will feel headache, nausea, vomiting, fatigue, etc. in a short time. Consequences, while VOC outdoors mainly come from fuel combustion and transportation. [0003] Therefore, the monitoring of volatile organic compounds is essential. The traditional VOC...
