室内环境中的大气微塑料（MPs）近年来引起了人们的广泛关注。在研究中，我们选取了五个室内研究案例，以不同年龄段的学生为研究对象，包括幼儿园、小学、初中、高中和大学。在不同的研究室中不断收集大气中的 MP 沉降物。同时，还研究了MP的形态特征和组成。由于室内环境特点不同，MPs污染程度差异较大。国会议员的丰度最高和最低分别出现在高中和幼儿园课堂。纤维是 MP 的主要形式，因为纤维很容易从纺织产品中分离出来。此外，MP的丰度与室内人口密度和人类活动持续时间显着相关。这项研究提供了不同研究室中大气MP的第一个证据，这可能有助于了解MP的环境行为，并为评估接触室内空气中MP的潜在风险提供进一步的信息。
The atmospheric microplastics (MPs) in indoor environment have attracted great attention in recent years. In the study, we selected five indoor study cases with students of different as the research objects, including kindergartens, primary schools, middle schools, high schools and university. The atmospheric MPs fallouts were continuously collected in the different study rooms. Simultaneously, the morphological characteristics and composition of MPs were also investigated. The level of MPs pollution greatly varied due to different characteristics of indoor environments. The highest and lowest abundance of MPs appeared in senior high school and kindergarten classroom, respectively. Fibers were the main form of MPs, since fibers were easily detached from the textile products. Besides, the abundance of MPs was significantly related to indoor population density and duration of human activity. This study provides the first evidence of atmospheric MPs in different study rooms, which could be helpful for understanding environmental behavior of MPs and providing further information to assess potential risks of exposure to indoor airborne MPs.
