湿地处理系统在世界各地广泛用于减少地表径流。虽然湿地处理氮减排已全面审查，常用的农药和抗生素对氮减排的影响仍然相对未经审查。因此，本综述旨在全面评估常用的农药和抗生素的去除及其对湿地处理系统中氮去除的影响，该系统接收来自城市和农业景观的非点源径流。在37个国家共确定了181项主要研究。大多数审查的出版物研究农药（n = 153）进入湿地系统，而抗生素（n = 29）的出版物较少。甚至更少的出版物回顾了进水混合物对湿地脱氮过程的影响（n = 16）。抗生素（35-100%），农药（-619-100%）和硝酸盐氮（-113-100%）的去除效率在研究中差异很大，农药和抗生素影响微生物群落，植被的存在和类型，时间和湿地生态系统中的水文。然而，对氮循环的影响取决于具体的新兴污染物。一个显着的知识差距仍然在湿地处理系统是如何用来处理非点源混合物，含有营养物质，农药和抗生素，导致一个未知的氮去除效率作为径流污染物的混合物演变。
Wetland treatment systems are used extensively across the world to mitigate surface runoff. While wetland treatment for nitrogen mitigation has been comprehensively reviewed, the implications of common-use pesticides and antibiotics on nitrogen reduction remain relatively unreviewed. Therefore, this review seeks to comprehensively assess the removal of commonly used pesticides and antibiotics and their implications for nitrogen removal in wetland treatment systems receiving non-point source runoff from urban and agricultural landscapes. A total of 181 primary studies were identified spanning 37 countries. Most of the reviewed publications studied pesticides (n = 153) entering wetlands systems, while antibiotics (n = 29) had fewer publications. Even fewer publications reviewed the impact of influent mixtures on nitrogen removal processes in wetlands (n = 16). Removal efficiencies for antibiotics (35–100%), pesticides (−619–100%), and nitrate-nitrogen (−113–100%) varied widely across the studies, with pesticides and antibiotics impacting microbial communities, the presence and type of vegetation, timing, and hydrology in wetland ecosystems. However, implications for the nitrogen cycle were dependent on the specific emerging contaminant present. A significant knowledge gap remains in how wetland treatment systems are used to treat non-point source mixtures that contain nutrients, pesticides, and antibiotics, resulting in an unknown regarding nitrogen removal efficiency as runoff contaminant mixtures evolve.
