Abstract
Particulate matter (PM) is a major environmental concern in Vietnam as well as in the world. Samples of PM2.5, PM10, and total suspended particle (TSP) were collected on the rooftop of a five-floor building inside Hanoi University of Science and Technology, Hanoi, from January to May 2015. The levels PM2,5, PM10, and the metal elements of TSP were determined. PM2,5 and PM10 had average concentrations of 73 ± 37 and 138 ± 67 μg\m3, respectively. The concentration of PM2,5 and PM10 in all samples were higher than the recommended level in the World Health Organization (WHO) guideline (2005) for 24h and annual concentrations of 25 and 50 μg\m3, respectively. Nineteen elements detected in TSP samples included the higher concentration group in order: Ca > Fe > Na > Al > Mg > K > Zn and in the lower concentration group: Pb > Mn > Ti > Sr > V > Cr > Cd. The potential sources revealed from element components were discussed.
微粒物质(PM)是越南乃至世界的一个主要环境问题。2015年1月至5月，在河内科技大学一栋五层楼的屋顶上采集了PM2.5、PM10和总悬浮颗粒(TSP)样本。测定了PM2、pm5、PM10及TSP中金属元素的含量。PM2、pm5和PM10的平均浓度分别为73±37和138±67 μg\m3。所有样本的PM2、pm5和PM10浓度均高于世界卫生组织(WHO)指南(2005)建议的24小时和年浓度水平，分别为25和50 μg\m3。TSP样品中检出19种元素，浓度较高组为Ca > Fe > Na > Al > Mg > K > Zn，浓度较低组为Pb > Mn > Ti > Sr > V > Cr > Cd。
