摘要

背景:Zayandeh-rud河是伊朗中部地区最重要的河流,本研究旨在为该河地表水和沉积物中的微塑料污染提供新的见解。方法:2021年7月,从沿河19个采样点采集水和沉积物样本。通过湿式过氧化物氧化(WPO)去除样品中的有机物,并通过在ZnCl2-饱和盐中浮选和在聚四氟乙烯(PTFE)膜过滤器上过滤来提取MPs。对过滤器上捕获的MP进行计数,并通过立体显微镜进行鉴定。结果:在沿河19个采样点中的13个采样点发现了MP。水样中MPs的最低和最高水平分别为0和51±16.5个颗粒/m3。除前两个采样点外,在所有采样点的沉积物中也检测到MPs(作为干沉积物,最大水平为58±25.9个颗粒/kg)。碎片是水和沉积物样品中最常见的MPs形状。72.3%的水样中检测到的MPs尺寸为1-5mm,而沉积物的这一百分比为49.2%。在水样和沉积物中发现的五种主要聚合物类型是聚对苯二甲酸乙二醇酯(PET)、聚乙烯(PE)、聚丙烯(PP)、聚苯乙烯(PS)和聚氯乙烯(PVC)。结论:Zayandeh-rud河水体和沉积物中的MPs水平以及塑料在环境中的长期存在对环境和人类健康构成了重大威胁,需要认真注意限制MPs排入河流。

Occurrence and characteristics of microplastics in surface water and sediment of Zayandeh-rud river, Iran
Background: Zayandeh-rud river is the most important river in the central regions of Iran and the present study aimed to provide new insights into microplastics (MPs) pollution in surface water and sediments of this river. Methods: Water and sediment samples were collected in July 2021 from 19 sampling sites along the river. Organics matters were removed from the samples by wet peroxide oxidation (WPO), and MPs were extracted by floatation in ZnCl2 -saturated salt and filtration on a polytetrafluoroethylene (PTFE) membrane filter. Trapped MPs on the filter were counted and qualified by a stereomicroscope. Results: MPs were found in 13 sites from 19 sampling sites along the river. The minimum and maximum levels of MPs in water samples were 0 and 51±16.5 particles/m3 , respectively. MPs also were detected in the sediments of all sampling sites except the first two sampling sites (the maximum level was 58±25.9 particles/kg as dry sediment). Fragments were the most common shape of MPs in both water and sediment samples. 72.3% of MPs detected in water samples were 1-5 mm in size, while this percentage for sediment was 49.2%. The five main polymer types found in water and sediment samples were polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyvinyl chloride (PVC). Conclusion: These levels of MPs in the water and sediments of Zayandeh-rud river and longtime persistence of plastics in the environment is a significant threat to environmental and human health and need serious attention to restrict MPs release into the river.
