Abstract：
Microplastic (MP) particles can be found all around the planet, even in Antarctica where they can be locally originated or transported by marine currents and winds. In this communication, we identify and report for the first time the contribution of a wastewater treatment plant (WWTP) as a local source of MP particles in the region. The analysis of the entire sample using micro-Raman spectroscopy revealed an MP concentration that ranged from 64 to 159 particles per liter of wastewater. >90 % of the identified particles were smaller than 50 μm. Among those analyzed, microplastics were identified as polyethylene, polypropylene, polyvinyl chloride, polytetrafluoroethylene, polyethylene terephthalate, and polystyrene. These findings demonstrate the need for urgent policies and technologies to mitigate this MP contamination source.
摘要：
微塑料（MP）颗粒可以在地球上找到，即使在南极洲，它们也可以在当地起源或通过海流和风运输。在这份通讯中,我们首次确定并报告了废水处理厂（WWTP）作为该地区MP颗粒的本地来源的贡献。使用显微拉曼光谱对整个样品的分析显示MP浓度范围为每升废水64至159个颗粒。>90%的鉴定颗粒小于50μm。在那些被分析的人中，微塑料被确定为聚乙烯，聚丙烯,聚氯乙烯,聚四氟乙烯,聚对苯二甲酸乙二醇酯，和聚苯乙烯。这些发现表明需要紧急的政策和技术来减轻这种MP污染源。
