Abstract

Endocrine-disrupting chemicals (EDCs) have recently gained prominence as emerging pollutants due to their significant negative impacts on diverse living forms in ecosystems, including humans, by altering their endocrine systems. EDCs are a prominent category of emerging contaminants in various aquatic settings. Given the growing population and limited access to freshwater resources, their expulsion from aquatic systems is also a severe issue. EDC removal from wastewater depends on the physicochemical properties of the specific EDCs found in each wastewater type and various aquatic environments. Due to these components' chemical, physical, and physicochemical diversity, various approaches based on physical, biological, electrochemical, and chemical procedures have been developed to eliminate them. The objective of this review is to provide the comprehensive overview by selecting recent approaches that showed significant impact on the best available methods for removing EDCs from various aquatic matrices. It is suggested that adsorption by carbon-based materials or bioresources is effective at higher EDC concentrations. Electrochemical mechanization works, but it requires expensive electrodes, continual energy, and chemicals. Due to the lack of chemicals and hazardous byproducts, adsorption and biodegradation are considered environmentally friendly. When combined with synthetic biology and an AI system, biodegradation can efficiently remove EDCs and replace conventional water treatment technologies in the near future. Hybrid in-house methods may reduce EDCs best, depending on the EDC and resources.

摘要

内分泌干扰化学物质(EDCs)由于其对生态系统中包括人类在内的各种生物形式的内分泌系统的显著负面影响,最近作为新兴污染物而备受关注。EDCs 是各种水生环境中新兴污染物的主要类别。由于人口增长和淡水资源有限,将它们从水生系统中排出也是一个严重的问题。从废水中去除 EDC 取决于每种废水中特定 EDC 的物理化学性质和各种水生环境。由于这些成分的化学、物理和物理化学多样性,已经开发了各种基于物理、生物、电化学和化学过程的方法来去除它们。本综述的目的是通过选择最近的方法提供全面的概述,这些方法对去除各种水生基质中 EDC 的最佳现有方法产生了重大影响。有人建议,碳基材料或生物资源的吸附在较高的 EDC 浓度下有效。电化学机械化工作,但它需要昂贵的电极、持续的能源和化学品。由于缺乏化学品和有害副产品,吸附和生物降解被认为是环保的。当与合成生物学和人工智能系统结合使用时,生物降解可以在不久的将来有效地去除 EDCs,并取代传统的水处理技术。根据 EDC 和资源的不同,内部混合方法可能会更好地去除 EDCs。
