Study on the Impact of Changes of Gaseous Pollutant SO2 Index on Human Health in Gansu Plateau in the Past Three Years

Abstract

Abstract The literature data method, instrument measurement method and mathematical statistics method are used to track the changes of SO2 in the Gansu Plateau in the past three years. The results show that the daily variation of SO2 in the Gansu Plateau has a double peak, the monthly variation shows a “U” shape with high data at both ends, and the annual variation shows that the SO2 index is decreasing year by year. In response to the above data changes, coping strategies are proposed from the perspective of human health.
