Microplastics (MPs) and nanoplastics (NPs) seriously contaminate environments by adsorbing environmentally hazardous chemicals. NPs (<1 µm) are not removed by conventional wastewater treatment processes, and have strong sorption capacity for the environmentally hazardous chemicals because of their high surface area. This study revealed that large amounts of MPs are generated in the eye-glass lens polishing process. Qualitative analyses of MPs were performed via Fourier-transform infrared (FTIR) and Raman spectroscopy. Particle size distribution was measured through particle size analysis based on light diffraction. MPs were quantified in the wastewater by measuring the mass balance using membrane filtration with polyaluminum chloride coagulation. One liter of wastewater contained 1380–62 539 g MPs and 0.0136–0.0324 mg NPs. Wastewater from 140 000 eye-glass shops in South Korea is discharged into wastewater plants, and about 57 g NPs per day pass through the wastewater treatment process. The amount of NPs that accumulate daily is likely to increase dramatically. Increased heavy metal concentrations after acid digestion confirmed that MPs in the wastewater adsorbed heavy metals. Detection of various types of volatile organic compounds in the wastewater indicated that workers in eye-glass shops are exposed to the significantly hazardous environments.

微塑料 (MPs) 和纳米塑料 (NPs) 通过吸附对环境有害的化学物质严重污染环境。NPs (<1 µm) 不能通过传统的废水处理工艺去除，并且由于其高表面积而对环境有害化学品具有很强的吸附能力。该研究表明，在眼镜镜片抛光过程中会产生大量 MP。MP 的定性分析通过傅里叶变换红外 (FTIR) 和拉曼光谱进行。通过基于光衍射的粒度分析测量粒度分布。通过使用聚合氯化铝凝聚的膜过滤测量质量平衡，对废水中的 MPs 进行量化。一升废水含有 1380–62 539 g MPs 和 0.0136–0.0324 mg NPs。韩国 14 万家眼镜店的废水被排放到污水厂，每天约有 57 克 NPs 通过废水处理过程。每天积累的 NP 数量可能会急剧增加。酸消化后重金属浓度增加证实废水中的 MPs 吸附了重金属。废水中各种挥发性有机化合物的检测表明，眼镜店的工人暴露在非常危险的环境中。酸消化后重金属浓度增加证实废水中的 MPs 吸附了重金属。废水中各种挥发性有机化合物的检测表明，眼镜店的工人暴露在非常危险的环境中。酸消化后重金属浓度增加证实废水中的 MPs 吸附了重金属。废水中各种挥发性有机化合物的检测表明，眼镜店的工人暴露在非常危险的环境中。
