Respiratory Diseases in Petrochemical Cities in Western China
Author(s): Chang Lu*, Wang Xia, Ding Haixia and Zhou Yian
In the urban and suburban areas of Lanzhou, a petrochemical industry city located in Northwest China, 99 Volatile Organic Compounds (VOCs) excluding aldehydes and ketones were measured using both PAMS and TO-15 methods between 2021 and 2022. The analysis of the collected data aimed to explore the seasonal trends in air pollution and its correlation with respiratory diseases in Lanzhou. The average annual concentrations of VOCs were found to be 121 ppbv for urban living areas, 165 ppbv for industrial areas, and 114 ppbv for background areas, with industrial areas exhibiting the highest concentration. These VOCs consist of various organic compounds, including alkanes, olefins, halogenated hydrocarbons, and aromatic hydrocarbons, which act as organic tracers of specific marker molecules or their sources. By employing principal component analysis and grouping the species using the maximum.. View More»
