Embodiment 1
[0043] Take the water samples (W1~W13) and soil samples (S1~S6) collected in the Fuling area of Chongqing for a total of 17 samples for rapid screening of chemicals of high concern. Ultra-high performance liquid chromatography-quadrupole / The electrostatic field orbitrap high-resolution mass spectrometry is used for rapid screening, matching with the mass spectrometry library search of chemicals of high concern. The measurement method includes the following steps:
[0044] Step 1: Sample collection:
[0045] In July 2018, we collected Chongqing Rudong Yangkou Chemical Park, Jianfeng Wujiang Bridge, Panjiaba Sewage Outlet, Panjiaba Sewage Sewage Outlet, Lizhi Wujiang Bridge, Fuling Wujiang Second Bridge, Shibangou Yangtze River Bridge, Fuling Yangtze River Bridge , Qingcaobei Yangtze River Bridge, Longqiao Sewage Treatment Plant (sewage body, discharge outlet), Baitao Sewage Treatment Plant discharge outlets set 13 points (W1 ~ W13), 1L in a brown glass bottle, collect 13 samples...
Embodiment 2
[0063] Taking a total of 22 samples collected in the Three Gorges area (W1~W22) for rapid screening of chemicals of high concern as an example, ultra-high performance liquid chromatography-quadrupole / electrostatic field orbitrap high-resolution mass spectrometry is used for rapid screening Check the sample and match it with the mass spectrometry library search for chemicals of high concern. The measurement method includes the following steps:
[0064] Step 1: Sample collection
[0065] In July 2019, collected the Three Gorges Zhuankou, Honghu Xintankou, Honghu Luoshan Town, Chenglingji, Shishouxiulin Town, Guanyin Temple, Chenjiadian, Gezhouba, Taipingxi, Jiuwanxi, Qinggan River, Xiangxi River, Badong Guandukou, Quchitan, Wushan Yangtze River Bridge, Fengjie County Yangtze River Bridge, Modaoxi, Dazhou, Chungzhou Town Shunxichang, Fengcheng Huangcao Gorge, Xiaoxi Tiansheng Bridge, Jialing River, a total of 22 points Position (W1~W22), 1L in a brown glass bottle, collect 22 sample...
