Article Synopsis
- This study examined volatile organic compounds (VOCs) pollution in Jinshan District, Shanghai, showing higher concentrations during polluted days compared to clear days, with mean values of 47.1 ppbv and 59.2 ppbv, respectively.
- The increase in daytime levels of alkenes was identified as a key factor driving atmospheric photochemistry during these polluted days, influenced by processes like VOC loss and ozone formation potential.
- Main sources of VOCs were found to be refining, petrochemicals, and oil and gas evaporation, highlighting the need for targeted measures in managing air quality and controlling reactive VOC emissions.
Article Synopsis
- Emissions from the iron and steel industry significantly contribute to air pollution, with a study in China's Yangtze River Delta analyzing volatile organic compounds (VOCs) and trace metals (TMs) between 2020 and 2022.
- The average concentration of VOCs was 58.2 ppbv, with benzene and ethylene being the most prevalent, and the study indicated higher ozone formation potential during the warmer season, highlighting a VOCs-limited condition for ozone creation.
- Health risk assessments revealed concerning cancer risks associated with exposure, particularly from chemicals such as chromium, nickel, and benzene, suggesting a need for improved raw material quality and pollution control measures in the industry.
Wuhan Tianhe International Airport (WUH) was suspended to contain the spread of COVID-19, while Shanghai Hongqiao International Airport (SHA) saw a tremendous flight reduction. Closure of a major international airport is extremely rare and thus represents a unique opportunity to straightforwardly observe the impact of airport emissions on local air quality. In this study, a series of statistical tools were applied to analyze the variations in air pollutant levels in the vicinity of WUH and SHA.

Results showed the concentration of VOCs was 51.63 ± 36.
