Microplastics are widely spread in the environment, which along with still increasing production have aroused concern of their impacts on environmental health. The objective of this study is to quantify the number and mass of two most common textile fibers discharged from sequential machine washings to sewers. The number and mass of microfibers released from polyester and cotton textiles in the first wash varied in the range 2.1 × 10 to 1.3 × 10 and 0.12 to 0.33% w/w, respectively. Amounts of released microfibers showed a decreasing trend in sequential washes. The annual emission of polyester and cotton microfibers from household washing machines was estimated to be 154,000 (1.0 × 10) and 411,000 kg (4.9 × 10) in Finland (population 5.5 × 10). Due to the high emission values and sorption capacities, the polyester and cotton microfibers may play an important role in the transport and fate of chemical pollutants in the aquatic environment.
微塑料广泛分布于环境中，其产量仍在不断增加，这引起了人们对其环境健康影响的关注。本研究的目的是定量测定从连续洗衣机排放到污水中的两种最常见的纺织纤维的数量和质量。聚酯纤维和棉纺织品在第一次洗涤中释放的微纤维的数量和质量分别在 2.1×10 到 1.3×10 和 0.12 到 0.33%w/w 的范围内变化。释放的微纤维数量在连续洗涤中呈下降趋势。据估计，芬兰（人口 5.5×10）家庭洗衣机每年排放的聚酯和棉微纤维分别为 154,000（1.0×10）和 411,000kg（4.9×10）。由于排放值和吸附能力较高，聚酯纤维和棉纤维可能在化学污染物在水环境中的迁移和归宿中发挥重要作用。
