Determination of perfluorinated compounds， antibiotics and pesticides in drinking water by automated solid phase extraction with ultra-performance liquid chromatography-tandem mass spectrometry

， the contents of perfluorooctanoic acid， 2，4-dichlorophenoxyacetic acid， atrazine， carbofuran， and bentazone were significantly lower than the national standard limits， indicating a low health risk associated with these compounds in the source water of the studied regions. This method is efficient， rapid， and cost-effective， which is suitable for the simultaneous determination of PFCs， antibiotics， and pesticides in drinking water. This method provides strong technical support for the control and treatment of new contaminants in drinking water.
