In the recent past, a class of emerging contaminants particularly endocrine disrupting compounds (EDCs) in the aquatic environment have gained a lot of attention. This is due to their toxic behaviour, affecting endocrine activities in humans as well as among aquatic animals. Presently, there are no regulations and discharge limits for EDCs to preclude their negative impact. Furthermore, the conventional treatment processes fail to remove EDCs efficiently. This necessitates the need for more research aimed at development of advanced alternative treatment methods which are economical, efficient, and sustainable. This paper focusses on the occurrence, fate, toxicity, and various treatment processes for removal of EDCs. The treatment processes (physical, chemical, biological and hybrid) have been comprehensively studied highlighting their advantages and disadvantages. Additionally, the use of agri-waste based adsorption technologies has been reviewed. The aim of this review article is to understand the prospect of application of agri-waste based adsorbents for efficient removal of EDCs. Interestingly, research findings have indicated that the use of these low-cost and abundantly available agri-waste based adsorbents can efficiently remove the EDCs. Furthermore, the challenges and future perspectives on the use of agri-waste based adsorbents have been discussed.
在最近的过去，一类新兴的污染物，特别是水生环境中的内分泌干扰化合物（EDCs），引起了很多关注。这是由于它们的毒性行为，会影响人类和水生动物的内分泌活动。目前，还没有针对 EDCs 的规定和排放限制来防止其负面影响。此外，传统的处理工艺无法有效地去除 EDCs。这就需要更多的研究来开发经济、高效和可持续的先进替代处理方法。本文重点介绍了 EDCs 的出现、命运、毒性以及各种去除 EDCs 的处理工艺。对处理工艺（物理、化学、生物和混合）进行了全面研究，突出了它们的优缺点。此外，还综述了基于农业废弃物的吸附技术的应用。本文的目的是了解基于农业废弃物的吸附剂在高效去除 EDCs 方面的应用前景。有趣的是，研究结果表明，这些低成本且大量可用的基于农业废弃物的吸附剂可以有效地去除 EDCs。此外，还讨论了基于农业废弃物的吸附剂的使用面临的挑战和未来展望。
