摘要:

双酚A(BPA)及其类似物统称为双酚类化合物(BPs),这类物质主要用于生产聚碳酸酯塑料和环氧树脂,因此广泛分布于各类环境介质、人体组织及代谢产物中。现有研究表明,BPs会对神经系统、生殖系统、免疫系统和代谢系统产生不良影响。本文将固相支撑液液萃取(SLE)与超高效液相色谱-串联质谱(UHPLC-MS/MS)技术结合,建立了一种人体尿液中17种BPs的高通量测定方法。样品经酶解处理后,依次进行全自动SLE净化、氮吹浓缩和复溶等步骤。使用CAPCELL PAK ADME色谱柱(100 mm×2.1 mm,2 μm)进行分离,以0.05 mmol/L氟化铵水溶液和0.05 mmol/L氟化铵甲醇溶液作为流动相进行梯度洗脱。质谱检测采用电喷雾电离(ESI)负离子扫描模式,在多反应监测(MRM)模式下进行,通过保留时间及离子丰度比进行定性,内标法进行定量。在优化的条件下,17种BPs可实现有效分离。17种BPs在对应的质量浓度范围内线性关系良好,相关系数(r)≥0.998 6,检出限(LOD)为0.002~0.489 μg/L,定量限(LOQ)为0.005~0.986 μg/L。选取低本底含量的儿童混合尿样为基质,在低、中、高3个加标水平下进行加标回收试验,结果表明,17种BPs的回收率为61.1%~121.7%,日内精密度为1.3%~11.2%,日间精密度为3.7%~19.0%。采用本方法对50份随机尿样进行测定,结果表明,共有11种BPs被检出,其中双酚S(BPS)和BPA的检出率最高,分别为98.0%和86.0%,检出水平中位值分别为0.075 μg/L和0.829 μg/L。本文所建方法操作简便、灵敏可靠,适用于人体尿液中17种BPs的快速定量分析,可为人群BPs暴露风险评估提供有效的技术支撑。

Abstract:

Bisphenol A (BPA) and its analogs are collectively termed bisphenol compounds (BPs), which are predominantly utilized in the manufacturing of polycarbonate plastics and epoxy resins. BPs are ubiquitous in diverse environmental matrices, human tissues, and metabolic products. Extensive research has demonstrated that BPs exert adverse effects on the nervous, reproductive, immune, and metabolic systems. After exposure in humans, BPs are primarily excreted in urine. Consequently, the development of efficient and robust analytical methods for BPs quantification in urine is essential for assessing population exposure levels. In this study, solid supported liquid-liquid extraction (SLE) was combined with ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) technology to establish a high-throughput determination method for 17 BPs in human urine. After enzymatic hydrolysis treatment of the samples, the steps of fully automatic SLE purification, nitrogen blowing concentration and redissolution were carried out successively. Separation was performed using a CAPCELL PAK ADME chromatography column (100 mm×2.1 mm, 2 μm), and gradient elution was carried out with 0.05 mmol/L ammonium fluoride aqueous solution and 0.05 mmol/L ammonium fluoride methanol solution as the mobile phases. MS detection was carried out using the electrospray ionization (ESI) negative ion scanning mode under the multi-reaction monitoring (MRM) mode. Qualitative analysis was conducted based on retention time and ion abundance ratio, and quantitative analysis was performed using the internal standard method. Under the optimized conditions, 17 BPs can be effectively separated. The linear relationships of the 17 BPs within the corresponding mass concentration ranges were good, and the correlation coefficients (r) were ≥0.998 6, the limits of detection (LODs) and quantification (LOQ) were 0.002-0.489 μg/L and 0.005-0.986 μg/L, respectively. Children’s mixed urine samples with low background content were selected as the matrix, and then spiked recovery tests were conducted at three spiked levels (low, medium and high). The results showed that the recoveries of 17 BPs were 61.1%-121.7%, the intra-day RSDs were 1.3%-11.2%, and the inter-day RSDs were 3.7%-19.0%. This method was used to determine 50 random urine samples, and the results showed that a total of 11 BPs were detected. Among them, bisphenol S (BPS) and BPA had the highest detection rates, which were 98.0% and 86.0% respectively, and the median detection levels were 0.075 μg/L and 0.829 μg/L respectively. This method is simple to operate, sensitive and reliable. It is suitable for the rapid quantitative analysis of 17 BPs in human urine and can provide effective technical support for the risk assessment of BPs exposure in the population.
