Cheryl Dybas, in her December Feature article about microplastics, seems to have missed one very important aspect of the issue—namely, the origin of most of the microplastics in the environment. The vast majority of them do not come from toothpaste, cosmetics, or the breaking up of plastic bottles. They are fibers that are shed from our clothing. Initial studies in which microplastics were collected from aquatic systems by pulling nets at the surface missed this fact, because long thin shapes go through nets and are severely undercounted (Green et al. 2018). Most of these microfibers are derived from synthetic clothing; when laundered in washing machines they shed huge numbers of...

大多数微塑料来自衣服

谢丽尔·戴巴斯（Cheryl Dybas）在她12月关于微塑料的专题文章中，似乎错过了该问题的一个非常重要的方面，即环境中大多数微塑料的起源。它们中的绝大多数不是来自牙膏，化妆品或塑料瓶的破裂。它们是从我们的衣服上掉下来的纤维。最初的研究通过在水面拉网从水生系统中收集微塑料而忽略了这一事实，因为长而细的形状穿过网并被严重低估了（Green等人。2018）。这些超细纤维大多数来自合成服装。当在洗衣机中洗涤时，它们会掉下大量...
