A rapid and efficient method based on solid phase extraction and liquid chromatography-tandem mass spectrometry was validated, allowing the determination of the endocrine-disrupting herbicides (acetochlor, alachlor, amitrole and atrazine), fungicides (carbendazim, triadimefon, penconazole and propiconazole), and insecticides (carbaryl and carbofuran) in drinking water. Low method detection limits (0.01-0.64 ng/L) and method quantification limits (0.03-2.13 ng/L) were obtained with satisfactory recoveries and precision for the endocrine-disrupting pesticides. The method was applied for real drinking water samples collected in the area of the city of Hangzhou (Zhejiang, China); the results showed that carbendazim, atrazine and acetochlor were detected in the drinking water samples and acetochlor was the most detected analyte.

固相萃取和UHPLC-MS / MS测定饮用水样品中干扰内分泌农药的多残留方法的开发。

验证了基于固相萃取和液相色谱-串联质谱的快速有效方法,可测定干扰内分泌的除草剂(乙草胺,丙草胺、,虫和阿特拉津),杀菌剂(多菌灵,三唑酮,戊康唑和丙康唑),和饮用水中的杀虫剂(西维因和呋喃丹)。获得了低方法检测限(0.01-0.64 ng / L)和方法定量限(0.03-2.13 ng / L),对于干扰内分泌的农药,回收率和精密度均令人满意。该方法用于在杭州市(浙江)地区采集的真实饮用水样品;结果表明,在饮用水样品中检测出了多菌灵,azine去津和乙草胺,其中乙草胺是检测到最多的分析物。
