Analysis of Atmospheric Pollutants by Time Variation in Jinshan Petrochemical District, Shanghai
In order to provide theoretical basis and decision-making basis for the reasonable planning and layout of the industrial park in the future.We analyze the change trend of SO2,NO2,O3,PM10 and PM2.5 based on the atmospheric monitoring data from Shanghai Jinshan petrochemical site in 2014.Result:(1) The concentration of atmospheric pollutants has seasonal characteristics.SO2,NO2,PM10,PM2.5 with high concentration in Winter,low concentration in summer,O3 just in the opposite.(2)O3 has a single peak diurnal variation,and NO2,PM10,PM2.5 have two high values in one day.The photochemical reaction is intensified due to the enhancement of solar radiation,ground temperature rise and human activities.As less affected by solar radiation,SO2 daily change trend is not obvious.Concentration of pollutants in the wind indicate that major pollutants come from Jinshan Metro emissions.The emission of waste gas in chemical industry has a significant effect on the concentration of O3.
