背景:抗肿瘤药物(AD)是医疗保健中经常使用的药物,和医护人员可以在职业上接触广告。监测表面污染是评估AD职业暴露的常用方法。目的是开发和验证一种灵敏和定量的监测方法,以确定Pt的表面污染作为含PtAD的标记物。在四个瑞典医院工作场所监测了含PtAD的表面污染。
方法:开发了一种基于电感耦合等离子体质谱法的分析方法。关于不同的表面材料验证擦拭取样程序。研究收集的擦拭物样品的稳定性。通过擦拭取样监测工作场所表面以确定含Pt的AD的污染。
结果:开发了一种擦拭采样和分析方法,检出限为0.1pgPt/cm2。在从四个工作场所收集的擦拭样品中,有67%检测到Pt,浓度范围为<0.10至21100pg/cm2。在4%的样本中,在三个医院病房中检测到的Pt表面污染均高于建议的Pt卫生指导值(HGV)。在医院药房,9%的检测到的Pt表面污染高于最低的建议HGV。
结论:用户友好,具体,开发并验证了在工作环境中从AD中测定Pt表面污染的灵敏方法。在病房收集的样品中检测到的Pt表面污染之间观察到了很大的污染变化,这可能反映了病房之间处理金额和工作实践的差异。
BACKGROUND: Antineoplastic drugs (ADs) are frequently used pharmaceuticals in the healthcare, and healthcare workers can be occupationally exposed to ADs. Monitoring of surface contamination is a common way to assess occupational exposure to ADs. The objective was to develop and validate a sensitive and quantitative monitoring method to determine surface contaminations of Pt as a marker for Pt-containing ADs. The surface contaminations of Pt-containing ADs were monitored at four Swedish hospital workplaces.
METHODS: An analytical method was developed based on inductively coupled plasma mass spectrometry. The wipe sampling procedure was validated regarding different surface materials. The stability of collected wipe samples was investigated. Workplace surfaces were monitored by wipe sampling to determine contaminations of Pt-containing ADs.
RESULTS: A wipe sampling and analytical method with a limit of detection of 0.1 pg Pt/cm2 was developed. Pt was detected in 67% of the wipe samples collected from four workplaces, and the concentrations ranged from <0.10 to 21100 pg/cm2. In 4% of samples, the detected surface contaminations of Pt in three hospital wards were above proposed hygienic guidance value (HGV) of Pt. In the hospital pharmacy, 9% of the detected surface contaminations of Pt were above lowest proposed HGV.
CONCLUSIONS: A user-friendly, specific, and sensitive method for determination of surface contaminations of Pt from ADs in work environments was developed and validated. A large variation of contaminations was observed between detected surface contaminations of Pt in samples collected in wards, and it likely reflects differences in amounts handled and work practices between the wards.
