Microfibers and microplastics are widely recognized emerging pollutants, which have the potential to cause an Eco-toxicological effect. Cellulosic and synthetic fibers are being released almost equally to the environment. Synthetic fibers released were non-biodegradable resulting in a significant negative impact on the environment. In the present study, four different households using fully automated washing machines (2 top-load, 2 front-load) were studied in a domestic laundry environment under real conditions. Laundry effluents were collected and contaminants analysis was carried out. The results estimated that the average emission rate of the four households was 7,453,635 MF/7Kg (FL, H1), 7,375,500 MFs/6Kg (FL, H2), 10,692,255 MFs/7Kg (TL, H3) and 7,589,017 MFs/6.2Kg (TL, H4). Synthetic fiber's emission rate was only about 19 %, and the average length range of microfibers released was found to be in the range of ≤5 μm (48.64 %), and the least amount of emission was found in the >500 μm range (11.49 %).
微纤维和微塑料是广为人知的新兴污染物,它们有可能造成生态毒理学效应。纤维素纤维和合成纤维向环境中的释放量几乎相同。释放出的合成纤维不可生物降解,对环境造成了重大负面影响。在本研究中,在实际条件下的家庭洗衣环境中,对四个使用全自动洗衣机的不同家庭(2个上开盖式、2个前开盖式)进行了研究。收集了洗衣废水并进行了污染物分析。结果估计,这四个家庭的平均排放率分别为7,453,635根微纤维/7千克(前开盖式,家庭1)、7,375,500根微纤维/6千克(前开盖式,家庭2)、10,692,255根微纤维/7千克(上开盖式,家庭3)和7,589,017根微纤维/6.2千克(上开盖式,家庭4)。合成纤维的排放率仅约为19%,发现释放出的微纤维的平均长度范围在≤5微米(48.64%),在>500微米范围内的排放量最少(11.49%)。
