Current study aimed to evaluate the microplastics abundance in the surface waters of Chabahar Bay for the first time. 21 neuston net water samples were collected from 7 stations. Microplastics were visually counted by stereomicroscope, sorted into 4 size categories, 4 shape categories, and identified by ATR-FTIR spectroscopy. Density of microplastics varied from 0.07 ± 0.03 to 1.14 ± 0.27 with an average density of 0.49 ± 0.43 particle·m. Microplastics were mostly found in the shape of fibers. 69% of analyzed particles were polyethylene and polypropylene. Main colors of the collected microplastics were white, blue and red. The results showed that the largest number of microplastics was found at station near populated area. Therefore, it can be concluded that, there is a pressing-need to investigate the distribution of microplastics in sediments and biota of this Bay as well as their effects on marine life and human health.
本研究首次评估了恰巴哈尔湾表层水中的微塑料丰度。从 7 个站位采集了 21 个浮游生物网水样。使用立体显微镜对微塑料进行了目视计数，并根据粒径和形状进行了分类，然后通过衰减全反射傅里叶变换红外光谱法进行了鉴定。微塑料密度变化范围为 0.07±0.03 至 1.14±0.27，平均密度为 0.49±0.43 个·m。微塑料大多呈纤维状。分析的颗粒中 69%为聚乙烯和聚丙烯。收集到的微塑料的主要颜色为白色、蓝色和红色。结果表明，在靠近人口密集区的站位发现了最多的微塑料。因此，可以得出结论，迫切需要调查该海湾沉积物和生物群中微塑料的分布及其对海洋生物和人类健康的影响。
