Chemical Machinery and Equipment Network Policies and Regulations Chemical Machinery and Equipment.
Volatile organic compounds (VOCs) are important precursors that cause composite pollution in cities characterized by ozone (O3) and fine particulate matter (PM2.
5) pollution.
Some VOCs have carcinogenic, mutagenic, and teratogenic effects, and can directly affect Harm to human health

5) pollution.
Some VOCs have carcinogenic, mutagenic, and teratogenic effects, and can directly affect Harm to human health
.
In recent years, compound pollution characterized by O3 and PM2.
5 pollution has become the main problem of the atmospheric environment in Shandong Province.
Compared with the control of particulate matter, sulfur dioxide, and nitrogen oxide pollution, Shandong Province’s VOCs management foundation is weak, which has become a constraint in Shandong Province.
The bottleneck of continuous improvement of air quality
.
Shandong Province is a major petroleum refining province.
It has the largest refining capacity in the country, accounting for about 30% of the national capacity.
The petroleum refining industry accounts for 20.
6% of the province’s emissions of VOCs.
The VOCs pollution prevention and control capabilities of related companies are uneven.
There is an urgent need to formulate technical guidelines for pollution prevention and control based on the characteristics of VOCs emissions from enterprises in the petroleum refining industry in Shandong Province
