尽管人们对纳米粒子对人类健康和生态系统功能的影响认识不足，但在化妆品、防晒霜和电子设备等消费品中使用纳米粒子的情况在过去十年中大幅增加。此外，进入海洋和湖泊等自然生态系统的塑料废物的数量正在增加，处理后的塑料的降解会产生更小的纳米级颗粒。因此，了解塑料纳米颗粒如何进入并影响生物体是至关重要的。在这里，我们通过水生食物链（从藻类到水蚤）给鱼注射了24和27纳米聚苯乙烯纳米颗粒，并研究了对行为和代谢的影响。我们发现对鱼类的摄食和鱼群行为以及新陈代谢都有严重的影响；因此，我们得出结论，聚苯乙烯纳米颗粒对鱼类的行为和代谢都有严重的影响，并且常用的纳米颗粒可能对自然系统和由此产生的生态系统服务产生相当大的影响。
The use of nanoparticles in consumer products, for example, cosmetics, sunscreens, and electrical devices, has increased tremendously over the past decade despite insufficient knowledge about their effects on human health and ecosystem function. Moreover, the amount of plastic waste products that enter natural ecosystems, such as oceans and lakes, is increasing, and degradation of the disposed plastics produces smaller particles toward the nano scale. Therefore, it is of utmost importance to gain knowledge about how plastic nanoparticles enter and affect living organisms. Here we have administered 24 and 27 nm polystyrene nanoparticles to fish through an aquatic food chain, from algae through Daphnia, and studied the effects on behavior and metabolism. We found severe effects on feeding and shoaling behavior as well as metabolism of the fish; hence, we conclude that polystyrene nanoparticles have severe effects on both behavior and metabolism in fish and that commonly used nanosized particles may have considerable effects on natural systems and ecosystem services derived from them.
