Abstract

As environment emerging contaminants of anthropogenic origin, antidiabetic drugs are present in the range of high ng/L to ng/mL in the influent and the effluent of the waste water treatment plant (WWTP). The metformin compound is the most used hypoglycemic agent in the world. The aim of this study was to develop a new analytic method, based on solid phase extraction followed by liquid chromatography coupled with mass spectrometric detector (SPE-LC-MS/MS), for identification and quantification of 5 antidiabetic compounds (glibenclamide/glyburide, glimepiride, metformin, glipizide, guanyl urea, gliclazide) and one degradation product (guanyl urea). The investigated environmental samples were the influent and the effluent of four urbans WWTP’s. By validating of the analytical method, it was obtained low LOQ’s (0.2-4.5 ng/L), satisfactory recovery rates (53.6-116.8%), and corresponding performance parameters: inter-day precision (4.9-8.4%) and reproducibility (11.3-14.6%). The concentrations of antidiabetics were as follow in influent and effluent: metformin 76-2041ng/L and 2-206ng/L, gliclazide (14.1-42.4 ng/L, and 3.3-19.1), glipizide (7.5-11.2 ng/L and 6.5-10ng/L), guanyl urea (6.2-7.3 and 8.3-21.3 ng/L). The efficiency of elimination of the antidiabetics in WWTP’s was maximum for metformin (67.6-98.5%), followed, by gliclazide (72.9-78.2%). The lowest elimination efficiency was calculated for glipizide (10.7-13.3%). The guanyl urea undergoes a formation process (74.5-84.2%) in effluent, from the metformin contained in influent.

通过新的SPE-LC-MS / MS方法灵敏地检测废水样品中的抗糖尿病化合物和一种降解产物

作为环境中人为污染的新兴污染物,抗糖尿病药物在废水处理厂(WWTP)的进水和出水中的浓度在ng / L至ng / mL的范围内。二甲双胍化合物是世界上使用最广泛的降血糖药。这项研究的目的是开发一种新的分析方法,该方法以固相萃取,液相色谱和质谱检测器(SPE-LC-MS / MS)为基础,用于鉴定和定量5种抗糖尿病化合物(格列本脲/格列本脲,格列美脲,二甲双胍,格列吡嗪,鸟嘌呤脲,格列齐特)和一种降解产物(鸟嘌呤脲)。调查的环境样本是四个城市污水处理厂的进水和出水。通过验证分析方法,可以得到较低的最低定量限(0.2-4.5 ng / L),令人满意的回收率(53.6-116.8%),以及相应的性能参数:日间精度(4.9-8.4%)和可重复性(11.3-14.6%)。进水和出水中的降糖药浓度如下:二甲双胍76-2041ng / L和2-206ng / L,格列齐特(14.1-42.4 ng / L和3.3-19.1),格列吡嗪(7.5-11.2 ng / L和6.5) -10ng / L),胍基尿素(6.2-7.3和8.3-21.3 ng / L)。二甲双胍在污水处理厂中消除糖尿病的效率最高(67.6-98.5%),其次是格列齐特(72.9-78.2%)。计算出格列吡嗪的最低消除效率(10.7-13.3%)。鸟嘌呤尿素从进水中所含的二甲双胍在流出物中经历形成过程(74.5-84.2%)。进水和出水中的降糖药浓度如下:二甲双胍76-2041ng / L和2-206ng / L,格列齐特(14.1-42.4 ng / L和3.3-19.1),格列吡嗪(7.5-11.2 ng / L和6.5) -10ng / L),胍基尿素(6.2-7.3和8.3-21.3 ng / L)。二甲双胍在污水处理厂中消除糖尿病的效率最高(67.6-98.5%),其次是格列齐特(72.9-78.2%)。计算出格列吡嗪的最低消除效率(10.7-13.3%)。鸟嘌呤尿素从进水中所含的二甲双胍在流出物中经历形成过程(74.5-84.2%)。进水和出水中的降糖药浓度如下:二甲双胍76-2041ng / L和2-206ng / L,格列齐特(14.1-42.4 ng / L和3.3-19.1),格列吡嗪(7.5-11.2 ng / L和6.5) -10ng / L),胍基尿素(6.2-7.3和8.3-21.3 ng / L)。二甲双胍在污水处理厂中消除糖尿病的效率最高(67.6-98.5%),其次是格列齐特(72.9-78.2%)。计算出格列吡嗪的最低消除效率(10.7-13.3%)。鸟嘌呤尿素从进水中所含的二甲双胍在流出物中经历形成过程(74.5-84.2%)。二甲双胍在污水处理厂中消除糖尿病的效率最高(67.6-98.5%),其次是格列齐特(72.9-78.2%)。计算出格列吡嗪的最低消除效率(10.7-13.3%)。鸟嘌呤尿素从进水中的二甲双胍在流出物中经历形成过程(74.5-84.2%)。二甲双胍在污水处理厂中消除糖尿病的效率最高(67.6-98.5%),其次是格列齐特(72.9-78.2%)。计算出格列吡嗪的最低消除效率(10.7-13.3%)。鸟嘌呤尿素从进水中所含的二甲双胍在流出物中经历形成过程(74.5-84.2%)。
