摘要 为人类更好/现代的生活条件而开展的活动是自然生态系统污染物的主要来源。城市化和工业化中涉及的一些化合物被称为新兴污染物 (EC) 或新兴关注污染物。 EC 要么是化学物质，要么是源自天然来源，近年来环境问题和公共健康问题已引起人们的关注。 EC 进入废水处理系统，并作为直接产品或副产品从这里迁移到不同的生态系统。由于其生物降解性和光降解性较低，它们具有持久性，并且可以停留很长时间。此外，EC 在活细胞中积累并通过营养水平转化。技术的发展及其在日常生活中的应用/效用导致了各种成分的产生，这些成分被添加到自然生态系统中。处理/未经处理的废水进入淡水/海洋水体并积累在动物、植物和沉积物中。这些每天增加的污染物/污染物会导致现有生态系统平衡的变化。几乎每个国家的自然环境中都发现了EC，因此它们成为一个全球性问题。本综述讨论了选定的 EC 通过水和其他方式进入陆地生态系统的路线和运输，以及它们如何影响生态系统中的自然过程。本次综述重点介绍了个人护理产品、药品、多环芳烃、内分泌干扰物、纳米颗粒和微塑料等 EC。
Abstract Activities that were developed for better/modern living conditions of humans are the primary source of contaminants to the natural ecosystem. Some of the compounds involved in urbanization and industrialization are termed emerging contaminants (ECs) or contaminants of emerging concern. ECs are either chemical or derived from natural sources which environmental concerns and public health have been raised in recent years. ECs enter wastewater treatment systems and migrate from here to different ecosystems as direct or by-products. They are persistent and also stay for a long duration due to their less biodegradation and photodegradation nature. Also, ECs accumulated in living cells and transformed through trophic levels. Technological developments and their application/utility in daily life led to the production of various components that are being added to the natural ecosystem. The treated/untreated wastewater enters into fresh/marine water bodies and gets accumulated into fauna, flora, and sediments. These pollutants/contaminants that are getting added on an everyday basis bring about changes in the existing ecosystem balances. ECs have been found in almost every country’s natural environment, and as a result, they became a global issue. The present review discusses the route and transport of selected ECs into the terrestrial ecosystem through water and other means and how they influence the natural process in an ecosystem. The ECs such as personal care products, pharmaceuticals, polyaromatic hydrocarbons, endocrine disruptors, nanoparticles, and microplastics are highlighted in this review.
