In 2008, the Ministry of Environmental Protection issued the Standard Electronic Components for Pollutant Discharge in Electronic Industry (draft for comments).

The VOCs limit of existing enterprises is 80mg/m3, and that of new enterprises is 50mg/m3.

In 2008, the Ministry of Environmental Protection issued "Electronic Terminal Products of Pollutant Emission Standards for Electronic Industry" (draft for comments). The VOCs limit of existing enterprises is 70mg/m3, and that of new enterprises is 50mg/m3.

In 2008, the Ministry of Environmental Protection issued the Emission Standard of Pollutants in Electronic Industry: Flat Panel Display, Electric Vacuum and Photoelectric Devices (draft for comment). The VOCs limit of existing enterprises is 100mg/m3, and that of new enterprises is 80mg/m3.

In 20 15, the Ministry of Environmental Protection issued the Emission Standard of Pollutants for Electronic Industry (Draft for Comment), which stipulated that the maximum allowable emission concentration of non-methane total hydrocarbons was 100mg/m3, and the special emission limit was 80mg/m3, without involving TVOCs.

In 20 18, the Ministry of Environmental Protection issued the Emission Standard of Pollutants for Electronic Industry (the second draft for comments), which stipulated that the maximum allowable emission concentration of non-methane total hydrocarbons was 100mg/m3 and TVOCs was 150mg/m3. The exclusion limits are 50 and 100 respectively.

VOCs (volatile organic compounds) are common air pollutants, which are produced in paint production, chemical fiber industry, metal painting, chemical coatings, shoemaking and tanning, plywood manufacturing, tire manufacturing and other industries. Harmful volatile organic compounds mainly include acetone, toluene, phenol, dimethylaniline, formaldehyde, n-hexane, ethyl acetate and ethanol.
