孕妇尿酚类环境内分泌干扰物浓度检测的尿样收集方法比较

目的 · 探讨孕妇尿酚类环境内分泌干扰物检测的尿样收集方法,采用并比较2 种方法对尿双酚A(BPA)、三氯生(TCS) 与正壬基酚(4-n-NP)检测浓度的影响。方法 · 采用2 种方法收集孕晚期尿样:导尿管尿袋收集(n=176),聚丙烯(PP)尿杯收 集(n=642)。采用高效液相色谱-串联质谱(HPLC-MS/MS) 法检测尿BPA、TCS 及 4-n-NP 的浓度。验证实验采用PP 材质尿杯、 导尿管尿袋、低密度聚乙烯材质离心管及玻璃杯(阴性对照)留取同一妇女共 5 人的尿样。结果 · 导尿管尿袋收集的尿样BPA 浓 度几何均数为82.5 ng/mL(95% CI 为 71.4 - 95...

Summary:目的 · 探讨孕妇尿酚类环境内分泌干扰物检测的尿样收集方法,采用并比较2 种方法对尿双酚A(BPA)、三氯生(TCS) 与正壬基酚(4-n-NP)检测浓度的影响。方法 · 采用2 种方法收集孕晚期尿样:导尿管尿袋收集(n=176),聚丙烯(PP)尿杯收 集(n=642)。采用高效液相色谱-串联质谱(HPLC-MS/MS) 法检测尿BPA、TCS 及 4-n-NP 的浓度。验证实验采用PP 材质尿杯、 导尿管尿袋、低密度聚乙烯材质离心管及玻璃杯(阴性对照)留取同一妇女共 5 人的尿样。结果 · 导尿管尿袋收集的尿样BPA 浓 度几何均数为82.5 ng/mL(95% CI 为 71.4 - 95.4 ng/mL),比尿杯留取尿样的BPA 浓度高63 倍(几何均数1.3 ng/mL,95% CI 为 1.3 - 1.5 ng/mL); 2 种方法尿 TCS、4-n-NP 及肌酐浓度相似。验证实验的结果表明,相同个体的尿样,尿袋收集的尿 BPA 浓度远远 高于其他 3 种方法。结论 · 尿酚类环境内分泌干扰物浓度检测的尿样收集,用 PP 材质尿杯优于导尿管尿袋收集,PP 材质尿杯及低 密度聚乙烯材质试管适合于流行病学人群研究。

Objective · To compare urine sample collection methods for measuring urinary concentrations of phenolic endocrine disrupting chemicals including bisphenol A (BPA), triclosan (TCS), and 4-n-nonylphenol (4-n-NP) in pregnant women. Methods · Urine samples were collected from women at late pregnancy by two methods: urine catheter and collection bag (n=176), urine collecting containers made of polypropylene (PP) (n=642). Urinary concentrations of BPA, TCS and 4-n-NP were measured with high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method. Confirmation experiment used PP containers, urine catheter and collection bags, as well as low-density polyethylene (LDPE) tubes and glass containers as both negative controls to collect urine sampl
