While the technologies available today can generate high-quality water from wastewater, the majority of the wastewater treatment plants are not intended to eliminate emerging xenobiotic pollutants, pharmaceutical and personal care items. Most endocrine disrupting compounds (EDCs) and personal care products (PPCPs) are more arctic than most regulated pollutants, and several of them have acid or critical functional groups. Together with the trace occurrence, EDCs and PPCPs create specific challenges for removal and subsequent improvements of wastewater treatment plants. Various technologies have been investigated extensively because they are highly persistent which leads to bioaccumulation. Researchers are increasingly addressing the human health hazards of xenobiotics and their removal. The emphasis of this review was on the promising methods available, especially nanotechnology, for the treatment of xenobiotic compounds that are accidentally released into the setting. In terms of xenobiotic elimination, nanotechnology provides better treatment than chemical treatments and their degradation mechanisms are addressed.
虽然当今可用的技术可以从废水中生成高质量的水，但大多数废水处理厂并非旨在消除新兴的异生物质污染物、药物和个人护理用品。大多数内分泌干扰化合物（EDCs）和个人护理产品（PPCPs）比大多数受监管的污染物更具北极性，其中有几种具有酸性或关键官能团。EDCs 和 PPCPs 与痕量出现一起，为去除和随后改进废水处理厂带来了特定的挑战。由于它们具有高度持久性，导致生物蓄积，因此已经广泛研究了各种技术。研究人员越来越关注异生物质及其去除对人类健康的危害。本综述的重点是针对那些意外释放到环境中的异生物质化合物的有前途的处理方法，特别是纳米技术。就异生物质消除而言，纳米技术提供了比化学处理更好的处理效果，并且还解决了它们的降解机制。
