Abstract：
Cigarette butts (CBs) and Microplastics (MPs) have serious harmful effects on the environment and living organisms despite their small size. This research aims to investigate the abundance and pollution status of CBs and MPs in Tahtalı Dam Basin (West Anatolia, Türkiye) which is the most important drinking and irrigation water resources. Clean Environment Index (CEI) and Cigarette Butt Pollution Index (CBPI) were used to determine pollution degree of the basin. The total number of CBs were 1.478 items, the total number of MPs were 477 items/m2 in the basin. As a result of this study, MP particles weren\'t found in Balaban Stream. Highest number of MP particles observed in 100-250 μm (45%) size class. The most abundant MP type and colour were, fragment (54%) and white (42%), respectively. Polyethylene terephthalate (50%) was the most abundant type of polymer according to the ATR- FTIR analysis. As a result of the CEI and CBPI, the upstream stations of the stream were classified as \"clean\" status, while downstream sampling points of the stream and Balaban Lake coasts were classified as \"extremely dirty\" status. The calculated volumes of MP particulates from mining facility, agricultural and recreational activities indicate that anthropogenic factors are the most important MP source in the Tahtalı Dam Basin. This study is the first study about MP and CB pollution of the freshwater ecosystems in the region.
摘要：
烟头（CBs）和微塑料（MPs）尽管尺寸很小，但对环境和生物体有严重的有害影响。本研究旨在调查塔赫塔勒大坝盆地（西安纳托利亚，Türkiye）是最重要的饮用水和灌溉水资源。清洁环境指数（CEI）和烟头污染指数（CBPI）用于确定流域的污染程度。CBs总数为1.478项,流域议员总数为477件/平方米。作为这项研究的结果，在BalabanStream中没有发现MP颗粒。在100-250μm（45％）尺寸等级中观察到的MP颗粒数量最高。最丰富的MP类型和颜色是，碎片（54％）和白色（42％），分别。根据ATR-FTIR分析,聚对苯二甲酸乙二醇酯(50%)是最丰富的聚合物类型。由于CEI和CBPI，河流的上游站点被归类为“干净”状态，而河流和巴拉班湖海岸的下游采样点被归类为“极其肮脏”状态。采矿设施中MP颗粒的计算体积，农业和娱乐活动表明，人为因素是塔赫塔勒大坝盆地最重要的MP来源。这项研究是关于该地区淡水生态系统MP和CB污染的首次研究。
