Organic contamination has been recognized as a matter of concern, and simultaneous monitoring of various organic contaminants in the complex environment has always been a part of the efforts of scientists. In the present study, settled house dust (SHD) was selected to establish HPLC fingerprint method for simultaneously evaluating organic matters in an indoor environment. The relative standard deviations (RSDs) of the relative retention time (RRT) and relative peak area (RPA) for precision were 2.46% and 0.47%, respectively, while the RSDs of RRT and RPA for repeatability were 2.51% and 0.50%, respectively, and for stability within 24 h were 2.51% and 0.49%, respectively, which indicated good reliability of the method. Then, the method was used to evaluate the trend of indoor organic matters of Yunyan district (urban) and Gangou village (rural) from 2012 to 2014. The results showed the overall organic matters of Yunyan did not change significantly within 2 years, while the organic matters of Gangou village were a little aggravated by the appearance of some suspicious matters. Our study suggests a method with the capability of simultaneously evaluating various organic matters and a possibility for detecting those that are not currently on the list of priority organic contaminants.

HPLC指纹图谱方法的建立及其在复杂环境中有机物总体变化评估中的应用:以沉降的室内灰尘为例

人们已经意识到有机污染物是一个令人关注的问题,在复杂环境中同时监测各种有机污染物一直是科学家们努力的一部分。在本研究中,选择了室内灰尘(SHD)来建立HPLC指纹法,以便同时评估室内环境中的有机物。相对保留时间(RRT)和相对峰面积(RPA)的精密度的相对标准偏差(RSD)分别为2.46%和0.47%,而RRT和RPA的重复性的RSD分别为2.51%和0.50% ,且24 h内的稳定性分别为2.51%和0.49%,表明该方法具有良好的可靠性。然后,该方法用于评估2012年至2014年云岩区(城市)和甘沟村(农村)室内有机物的趋势。结果显示,云岩的总体有机物在两年内没有显着变化,而有机物一些可疑事物的出现使冈沟村的居民感到有些不安。我们的研究提出了一种能够同时评估各种有机物的方法,并有可能检测出那些目前不在优先有机污染物列表中的有机物。
