摘要
为了探讨银川大学附近农田大气中苯系物的污染水平与现状,以银川大学为中心,确立了4个采样点,采用固体吸附/热脱附-气相色谱法分析,得出了银川大学环境空气中苯系物的污染水平。
In order to investigate the pollution level and present situation of BTEX in the atmosphere of Yinchuan city, taked Yinchuan university as the center, four sampling points and sampling period and frequency were established by investigating the situation of the nearby farmland.Using solid adsorption/thermal desorption gas chromatography analysis, the BTEX pollution levels in Yinchuan university of farmland in the vicinity of atmospheric were obtained.
