微塑料是长度小于5毫米的塑料颗粒。空气中的微塑料可被人类摄取和吸入。在这项工作中，对路边区域的三个地点进行了微塑料调查。空气样品是通过真空泵将这三个位置的空气吸入不锈钢漏斗中获得的。空气通过过滤介质以保留任何颗粒，然后收集这些颗粒，并用数字显微镜和傅里叶变换红外(FTIR)测试进行观察。在现场发现了多种微塑料形状，包括纤维、碎片和薄膜。在任何部位都没有发现微球，微塑料的主要形状是纤维。在高交通流量的研究地点，微塑料含量最高，而在低交通流量的研究地点，微塑料含量最高。Microplastic on Urip Sumoharjo street (225,087 units/day) as many as 174.97 particles/m3 and 130.50 particles/m3， Mayjend Sungkono street (132,066 units/day) as many as 131.75 particles/m3 and 68.36 particles/m3，和Embong玛朗街(98,017单位/天)94.69粒子/m3和55.93粒子/m3。 Microplastics from different polymers, such as polyethene terephthalate (PET), polyester and cellophane, were identified. Thus, dust emissions and depositions in the air, on land surfaces, and in aquatic environments are associated with microplastic transportation.
