Pharmaceuticals and personal care products (PPCPs) are a group of emerging micro-pollutants causing detrimental effects on living organisms even at low doses. Previous investigations have confirmed the presence of PPCPs in the environment at hazardous levels, mainly due to the inefficiency of conventional wastewater treatment plants (CWWTPs). Their stable structure induces longer persistence in the environment. Microalgae are currently used to bioremediate numerous pollutants of different characteristics and properties released from the domestic, industrial, agricultural, and farm sectors. CO2 mitigation during culture and the use of biomass as feedstock for biodiesel or biofuel production are, briefly, other benefits of microalgae-mediated treatment over CWWTPs. This review provides a comprehensive summary of recent literature, an overview of approaches and treatment systems, and breakthrough in the field of algal-mediated removal of PPCPs in wastewater treatment processes. The mechanisms involved in phycoremediation, along with their experimental approaches, have been discussed in detail. Factors influencing the removal of PPCPs from aqueous media are comprehensively described and assessed. A comparative study on microalgal strains is analyzed for a more efficient implementation of future processes. The role of microalgae to mitigate the most severe environmental impacts of PPCPs and the generation of antibiotic-resistant bacteria is discussed. Also, a detailed assessment of recent research on potential toxic effects of PPCPs on microalgae was conducted. The current review highlights microalgae as a promising and sustainable approach to efficiently bio-transform or bio-adsorb PPCPs.

使用微藻类去除废水中的药品和个人护理产品(PPCP):综述

药品和个人护理产品(PPCP)是一类新兴的微污染物,即使在低剂量下也对生物体造成有害影响。先前的调查已确认环境中以危险水平存在PPCP,这主要是由于常规废水处理厂(CWWTP)效率低下所致。它们的稳定结构在环境中引起更长的持久性。微藻目前用于生物修复从家庭,工业,农业和农场部门释放的许多不同特性和特性的污染物。一氧化碳2简而言之,与CWWTP相比,微藻介导的处理的其他好处是,在培养期间的缓解和将生物质用作生物柴油或生物燃料生产的原料。这篇综述提供了最新文献的全面总结,方法和处理系统的概述,以及在废水处理过程中藻类介导的PPCP去除领域的突破。phycoremediation所涉及的机制及其实验方法已被详细讨论。全面描述和评估了影响从水性介质中去除PPCP的因素。分析了对微藻菌株的比较研究,以更有效地实施未来的流程。讨论了微藻在减轻PPCP对环境的最严重影响以及产生抗生素抗性细菌方面的作用。另外,对PPCP对微藻的潜在毒性作用的最新研究进行了详细评估。当前的评论强调了微藻是有效地生物转化或生物吸附PPCP的有前途和可持续的方法。
