With the development of society volatile organic compounds in the atmosphere are widely concerned. Many of these species are thought to be closely related to ozone in the atmosphere. Volatile organic compounds (VOCs) were collected for one year from March 2021 to February 2022 in three areas of petrochemical cities in Northwest China, including PAMs and 99 organic compounds in To-15 except aldehydes and ketones. These VOCs are composed of a variety of organic compounds, which include alkanes,

Principal component analysis was used to attribute species to statistical data using the maximum variance method and to score the VOC concentration levels in different areas. The change in correlation was then calculated from the number of respiratory morbidity cases obtained from public health hospitals in the respective regions. Studies have found a clear relationship between VOC concentration levels and the onset of respiratory disease in the fall and winter. in the fall and winter can effectively reduce public health risks.
