3. Effectiveness and achievement of local characteristic control Control or research work related to PM10 and PM2.5
The average mass concentrations of PM10, PM2.5 and PM2.5-10 measured by designated stations from January to October 2021 without distinguishing the influence of airflow sources were 20, 8 and 12 μg/m3, respectively; under the influence of the northeast monsoon, respectively 20, 8, and 12 μg/m3; under the influence of high-pressure backflow, 23, 10, and 13 μg/m3; under the influence of Pacific high pressure, 17, 6, and 11 μg/m3, respectively; under the influence of southwest airflow, 22, 9, and 13 μg/m3, respectively 13 μg/m3; 18, 10 and 8 μg/m3 under the influence of mainland China.
From January to October 2021, the predominant species of water-soluble ions in PM2.5 particles collected by designated stations in Hualien County under the influence of different airflow sources are all dominated by SO42-, while PM2.5-10 is affected by Pacific high pressure and southwest airflow. The dominant species is OC, and the rest of the airflow patterns are NO3-. The estimated water-soluble ion source of PM2.5 particles is the highest secondary derived salts, and PM2.5-10 particles are seawater-related ions and secondary derived salts. The proportions of both classes are equal. The estimation results of the water-soluble ion composition in the particles estimated by the chloride ion loss method showed that the PM2.5 particles were all dominated by ammonium sulfate salts; the PM2.5-10 particles were dominated by sodium chloride and sodium nitrate. On the whole, the characteristics of particles collected by designated stations in Hualien County from January to October 2021 are not much different from those of the same period last year, and the degree of pollution caused by immigration in 2021 will be less than that in 2020.
