Abstract

In this work, the amount and physical and chemical characteristics of airborne microplastics (MPs) pollution in dust samples in Sistan, located in the eastern part of Iran, is reported. Sampling stations were selected according to the wind direction and population density. MPs were collected by a static dust sampler and analyzed by optical microscopy and FT-IR spectroscopy. Results showed that the distribution frequency of MPs in residential and non-residential areas was 6 to 11 pieces per 100 g (pcs/100 g) with an average abundance of 9.8 pcs/100 g. Fragmented MPs were approximately consisted 64% of total MPs and their sizes were in the range of 0.9–3.8 mm. Polyethylene (49%), polystyrene (21%) and polyester (18%) were the main MPs presented in the dust samples. It was observed that population density and wind direction were the most important parameters affecting MPs pollution in dust.

锡斯坦大气粉尘样品中的微塑料:来源和分布

本文报道了伊朗东部锡斯坦地区粉尘样品中空气中微塑料(MPs)污染的数量和物理化学特征。根据风向和人口密度选择采样站。采用静态粉尘采样器采集MPs，并用光学显微镜和红外光谱分析。结果表明，MPs在居民点和非居民点的分布频率为6 ~ 11个/ 100g (pcs/ 100g)，平均丰度为9.8个/ 100g。碎片化MPs约占总MPs的64%，其大小在0.9 ~ 3.8 mm之间。聚乙烯(49%)、聚苯乙烯(21%)和聚酯(18%)是粉尘样品中主要的MPs。种群密度和风向是影响扬尘中MPs污染最重要的参数。
