摘要
微塑料（MPs）最近成为一个日益严重的环境污染问题。MPs很容易转移，并且在周围空气中无处不在。空气中的多聚体可作为几种有毒污染物的载体，暴露于多聚体可导致人类肺部疾病。聚对苯二甲酸乙二醇酯（PET）是用于制造各种纤维和塑料的最丰富的MPs之一。在这项研究中，我们提出了一种利用液相色谱-串联质谱（LC-MS/MS）测定空气中细颗粒物（PM2.5）可吸入部分中PET MPs质量浓度的方法。测试了聚四氟乙烯和石英纤维过滤器在测量空气中PET MPs质量浓度时的萃取效率。与石英纤维过滤器相比，聚四氟乙烯过滤器具有良好的回收率（80-120%）。利用该方法，在印度首都德里和印度-恒河平原（NWIGP）西北部的郊区城市莫哈里进行了一项试点研究，以确定空气中PM2.5中PET MPs的质量浓度。在德里和莫哈里观测到的空气中PM2.5中PET MPs的最大质量浓度分别为135.20 ng m - 3和157.98 ng m - 3。
Determination of mass concentrations of airborne PET microplastics using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS)†
Microplastics (MPs) have recently become a growing environmental pollution concern. MPs are easily transferred and ubiquitously found in ambient air. MPs in the air can act as carriers for several toxic pollutants, and exposure to MPs can lead to pulmonary diseases in humans. Polyethylene terephthalate (PET) is one of the most abundant MPs used in the manufacturing of various fibres and plastics. In this study, we present a method for the determination of mass concentrations of PET MPs in the airborne inhalable fraction of fine particulate matter (PM2.5) using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). Teflon and quartz fiber filters were tested for extraction efficiency in measuring the mass concentrations of airborne PET MPs. Teflon filters showed good recovery (80–120%) compared to quartz fiber filters. Using this method, a pilot study was carried out in Delhi, the national capital of India, and Mohali, a suburban city in the northwest Indo-Gangetic Plain (NWIGP), for the determination of mass concentrations of PET MPs present in airborne PM2.5. The observed maximum mass concentrations of PET MPs in airborne PM2.5 in Delhi and Mohali are 135.20 ng m−3 and 157.98 ng m−3, respectively.
