中文摘要:
      为研究PM2.5和PM10手工与自动监测仪器在高海拔地区的适用性,于2014年12月至2015年1月(冬季)在青海省西宁市开展了为期34 d的监测比对实验。PM监测数据表明:手工监测数据之间都有差异,除了受监测滤膜种类的影响,还存在监测仪器间的系统误差。石英滤膜的PM监测数据都高于聚丙烯滤膜,尤其是PM2.5更为明显,偏高近1/4;石英滤膜与聚丙烯滤膜的PM监测数据具有较好的相关性,PM10监测数据的相关系数为0.97。自动监测数据之间进行了同期比对研究,发现TEOM1405DF(微振荡天平法)和APM-2(β射线法)的PM监测值较低,BAM-1020(β射线法)的PM监测值最高;而Grimm(光散射法)的PM监测值居中。BAM1020配备动态加热系统(DHS),其PM监测数据比没有配备DHS的APM-2偏高40%。基于PM监测比对研究,建议在空气污染严重时加密对各监测仪器的运行维护,并加强长期观测以全面评估PM监测。
英文摘要:
      In order to study the applicability of PM2.5/PM10 manual and automatic monitoring instruments at high altitude, the 34 days observation campaign was conducted in Xining city, Qinghai province from Dec. 2014 to Jan. 2015. The PM monitoring data showed that there were some differences among the data from different manual monitoring instruments, which might be influenced by the different instrument types and the monitoring filters as well. The monitoring PM data from quartz filters were higher than those from polypropylene membrane filters; especially, the data difference for PM2.5 was much more obvious, nearly 1/4. While, the monitoring PM data from quartz filter and polypropylene membrane filter had good correlation, with the correlation coefficient of 0.97 for PM10 data. Paralleled monitoring data from online instruments were also compared. The PM monitoring data from TEOM1405DF instrument and APM-2 instrument were lower and from BAM-1020 instrument (Beta Ray method) were the highest; while those from Grimm instrument (Laser Light Scattering method) were in the middle. The PM monitoring data from BAM-1020 instrument with dynamic heating system were nearly 40% higher than those from APM-2 instrument without dynamic heating system. Based on this study, it was suggested that the operation maintenance for monitoring instruments and long-term observation should be strengthened when encounters continued heavy pollution weather.
