| This article is based on the United States'EPA method improved. In order to set up a method that how to detect the trace PPCPs in natural water samples. BP-3, BP-1, Caffeine, Carbamazepine, libenclamide, emfibrozil, lydrochlorothiazide, Ibuprofen, Naproxen, Triclocarban, Triclosan which are of pharmaceuticals and personal care products are selected as the target objects, and the conditions of solid-phase extraction and detection that used by UPLC-MS-MS instrument are optimized. At last, estimate the concentration of the 11 PPCPs that says above in the areas of Jiulong river estuary by means of detecting collecting water samples and observe the concentration of 11 targets before and after rainstorm to assess the impact of extreme weather condition on 11 targets. In the study site the experimental results suggest that different from the Hydrochlorothiazide, Carbamazepine, Ibuprofen and Triclocarban which remove from estuary, Glibenclamide and Benzophenone-1 have stable input, and only Caffeine and Gemfibrozil show conservative behavior. The experimental results also indicate that unlike caffeine whose concentration increases with the increase of rainfall, Naproxen and Carbamazepine decrease with the increase of precipitation, the concentration of other targets first rise and then drop with the increase of rainfall. |
