摘要

本研究调查了从医院废水处理厂(WWTP)和伊朗克尔曼沙阿卡拉苏河收集的微塑料(MPs)表面是否存在严重急性呼吸系统综合征冠状病毒 2(SARS-CoV-2)RNA。利用立体、扫描电子和傅立叶变换红外光谱对微塑料进行了表征,以确定其外观、定量、定性和形态。用蒸馏水冲洗 MP 表面,提取病毒 RNA,然后将划痕材料交换并转移到病毒运输培养基中。使用 SARS-CoV-2 分子检测试剂盒和实时定量聚合酶链反应(RT-qPCR)进行鉴定。废水中最常见的 MPs 可作为病毒 RNA 的载体,而病毒 RNA 只在一个河水样本中被发现。这些发现表明,多孔介质可促进病毒通过污水处理厂传播到受纳水体。因此,应重视对作为 COVID-19 病毒载体的 MPs 的研究,因为确定 MPs 表面是否存在冠状病毒对于确定一个国家的卫生战略至关重要。此外,这项研究还表明,多孔介质有可能成为病原体的载体,并在水生环境中创造新的微生物生态位。

Microplastic occurrence and its potential role as a carrier for SARS-CoV-2 in health center wastewater treatment plant and surface water

This study investigated the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNAs on the surface of microplastics (MPs) collected from a hospital wastewater treatment plant (WWTP) and the Qara-sou river in Kermanshah, Iran. The MPs were characterized using stereo-, scanning electron-, and Fourier-transform infrared spectroscopies to determine their appearance, quantification, qualification, and morphology. The virus RNAs were extracted by rinsing the surface of the MPs with distilled water, followed by swapping and transferring the scratched material into viral transport medium. Identification was performed using SARS-CoV-2 molecular detection kits and real-time quantitative polymerase chain reaction (RT-qPCR). The most common type of MPs found in the wastewater acted as a vector for the virus RNA, whereas virus RNA was only identified in one sample of river water. These findings suggest that MPs can facilitate the spread of the virus through WWTPs and into receiving water bodies. Thus, research on MPs acting as carriers of COVID-19 should be emphasized as determining the presence of the coronavirus on the surface of MPs is crucial in determining a country's health strategies. Furthermore, this study shows that MPs have the potential to act as vectors for pathogens and create new microbial niches in aquatic environments.

期刊介绍: The Journal of Sea Research is an international and multidisciplinary periodical on marine research, with an emphasis on the functioning of marine ecosystems in coastal and shelf seas, including intertidal, estuarine and brackish environments. As several subdisciplines add to this aim, manuscripts are welcome from the fields of marine biology, marine chemistry, marine sedimentology and physical oceanography, provided they add to the understanding of ecosystem processes.
