采用直读式Dust Trak8520型颗粒物浓度测定仪对陶瓷生产区附近空气中PM10、PM2.5和PM1质量浓度进行了测定。结果表明PM10、PM2.5和PM1日平均质量浓度变化趋势相似,三者之间存在显著的相关性。连续十日PM10、PM2.5和PM1平均质量浓度分剐为0．253mg／m3、0．224mg／m3,0．188mg／m3,PM2.5/PM10、PM1／PM10与PM1／PM2.5的平均值分别为0．88、0．74与0．84,表明陶瓷生产区空气中颗粒物污染比较严重,且细粒子在PM10中比例有增大的趋势。
The concentration of PM10, PM2.5 and PM1 in the air near the ceramic production area was measured by direct reading Dust Trak8520 particle concentration meter. The results showed that PM10, PM2.5 and PM1 daily average concentration of the quality of the variation is relatively homogeneous, there is a significant correlation between the three. The average mass concentrations of PM10, PM2.5 and PM1 on the ten consecutive days were 0.253mg / m3, 0.224mg / m3 and 0.188mg / m3, respectively, and PM2.5 / PM10, PM1 / PM10 and PM1 / PM2.5 The average values were 0.88, 0.74 and 0.84, respectively, indicating that the particulate matter in the air in the ceramic production area is more polluted and the proportion of fine particles in PM10 tends to increase.
