Characteristics and Influencing Factors of Atmospheric Environment Quality in Jinan City during National Holiday |
| |
| Abstract: | The atmospheric environment quality of Jinan is analyzed with correlation analysis and principal component analysis method.Peak concentrations of dominant pollutants like PM2.5 and PM10 appeared in 9:00 and 23:00, valley values appeared in 14:00.The daily average concentrations exceeded the national secondary standard, PM2.5 rose by 33.6% and PM10 rose by 34%on October 1st.The maximum concentrations during National Holiday and the minimum concentrations on 6th.The concentrations PM2.5 and PM10 picked up rapidly on 7th.Making reasonable arrangements to avoid the peak tour can alleviate the ambient pres-sure and promote sustainable development of the city. |
