Various organic pollutants so-called emerging pollutants (EPs), including active residues from pharmaceuticals, pesticides, surfactants, hormones, and personal care products, are increasingly being detected in numerous environmental matrices including water. The persistence of these EPs can cause adverse ecological and human health effects even at very small concentrations in the range of micrograms per liter or lower, hence called micropollutants (MPs). The existence of EPs/MPs tends to be challenging to mitigate from the environment effectively. Unfortunately, most of them are not removed during the present-day treatment plants. So far, a range of treatment processes and degradation methods have been introduced and deployed against various EPs and/or MPs, such as ultrafiltration, nanofiltration, advanced oxidation processes (AOPs) and enzyme-based treatments coupled with membrane filtrations. To further strengthen the treatment processes and to overcome the EPs/MPs effective removal dilemma, numerous studies have revealed the applicability and notable biocatalytic potentialities of laccases and peroxidases to degrade different classes of organic pollutants. Exquisite selectivity and unique catalytic properties make these enzymes powerful biocatalytic candidates for bio-transforming an array of toxic contaminants to harmless entities. This review focuses on the use of laccases and peroxidases, such as soybean peroxidase (SBP), horseradish peroxidase (HRP), lignin peroxidase (LiP), manganese peroxidase (MnP), and chloroperoxidase (CPO) as a greener oxidation route towards efficient and effective removal or degradation of EPs/MPs.
各种有机污染物，即所谓的新兴污染物（EPs），包括来自药品、农药、表面活性剂、激素和个人护理产品的活性残留，越来越多地在包括水在内的众多环境基质中被检测到。这些 EPs 的持久性即使在微克/升或更低的非常小浓度范围内，也会对生态和人类健康产生不利影响，因此被称为微量污染物（MPs）。从环境中有效减轻这些污染物的存在往往具有挑战性。不幸的是，目前的处理厂大多数情况下都无法去除这些污染物。迄今为止，已经引入和部署了一系列处理工艺和降解方法来处理各种 EPs 和/或 MPs，例如超滤、纳滤、高级氧化工艺（AOP）和基于酶的处理方法与膜过滤相结合。为了进一步加强处理工艺并克服 EPs/MPs 的有效去除难题，许多研究表明漆酶和过氧化物酶在降解不同类有机污染物方面的适用性和显著的生物催化潜力。漆酶和过氧化物酶具有出色的选择性和独特的催化特性，使这些酶成为将各种有毒污染物生物转化为无害物质的强大生物催化候选物。本综述重点介绍了漆酶和过氧化物酶（如大豆过氧化物酶（SBP）、辣根过氧化物酶（HRP）、木质素过氧化物酶（LiP）、锰过氧化物酶（MnP）和氯化过氧化物酶（CPO））作为一种更绿色的氧化途径，用于有效去除或降解 EPs/MPs。
