文摘

Error Estimation (EE) analysis based on PMF Model was used to identify an optimal solution. Correlations between PM2.5 concentrations and ratios (SO42-/NO3− and OC/EC) were analysed. Secondary source, coal combustion and vehicle exhaust were major sources to PM2.5 at Heze. Shandong, Henan and Jiangsu were major potential sources-areas of PM2.5 at Heze.
