Rampant industrial boom, urbanization, and exponential population growth resulted in widespread environmental pollution, with water being one of the leading affected resources. All kinds of pollutants, including phenols, industrial dyes, antibiotics, pharmaceutically active residues, and persistent/volatile organic compounds, have a paramount effect, either directly or indirectly, on human health and aquatic entities. Strategies for affordable and efficient decontamination of these emerging pollutants have become the prime focus of academic researchers, industry, and government to constitute a sustainable human society. Classical treatment techniques for environmental contaminants are associated with several limitations, such as inefficiency, complex pretreatments, overall high process cost, high sludge generation, and highly toxic side-products formation. Enzymatic remediation is considered a green and ecologically friendlier method that holds considerable potential to mitigate any kinds of contaminating agents. Exploiting the potential of various peroxidases for pollution abatement is an emerging research area and has considerable advantages, such as efficiency and ease of handling, over other methods. This work is designed to provide recent progress in deploying peroxidases as green and versatile biocatalytic tools for the degradation and transformation of a spectrum of potentially hazardous environmental pollutants to broaden their scope for biotechnological and environmental purposes. More studies are required to explicate the degradation mechanisms, assess the toxicology levels of bio-transformed metabolites, and standardize the treatment strategies for economic viability.
工业蓬勃发展、城市化和人口的指数级增长导致了广泛的环境污染，而水是受影响最严重的资源之一。各种污染物，包括酚类、工业染料、抗生素、药物活性残留和持久性/挥发性有机化合物，直接或间接地对人类健康和水生生物都有极大的影响。对于这些新兴污染物，开发经济高效的去除策略已成为学术界、工业界和政府的主要关注点，以构建可持续的人类社会。对于环境污染物的经典处理技术存在一些局限性，例如效率低、预处理复杂、总成本高、污泥产生量大以及有毒副产物形成等问题。酶修复被认为是一种绿色且生态友好的方法，具有很大的潜力来减轻各种污染物的影响。利用各种过氧化物酶来消除污染是一个新兴的研究领域，与其他方法相比，它具有效率高、易于操作等优势。这项工作旨在提供利用过氧化物酶作为绿色、多功能生物催化工具来降解和转化一系列潜在危险环境污染物的最新进展，以扩大其在生物技术和环境方面的应用范围。需要更多的研究来阐明降解机制、评估生物转化代谢物的毒理学水平，并为经济可行性制定标准化的处理策略。
