The effect of catchment revegetation on waterways. This project will examine the forms, transformations and fate of dissolved organic matter (DOM) in aquatic ecosystems and the link to human health with water treatment. Catchment revegetation is a management tool used to reduce excessive nutrient loads to waterways, which in turn causes poor water quality. However, catchment revegetation also produces DOM. DOM is typically poorly characterised and its effect on ecosystem health unclear. DOM also reacts with chlorine in water treatment plants to form disinfection by-products that affect human health. This research is expected to provide important new information to guide future catchment restoration efforts.

集水区重新植被对水道的影响。该项目将研究水生态系统中溶解有机物（DOM）的形式、转化和归宿，以及水处理与人类健康的联系。集水区重新植被是一种管理工具，用于减少水道中过多的养分负荷，这反过来又会造成水质差。然而，集水区植被重建也会产生DOM。DOM的特征通常很差，其对生态系统健康的影响尚不清楚。DOM还与水处理厂的氯反应，形成影响人类健康的消毒副产品。这项研究预计将提供重要的新信息，以指导未来的集水区恢复工作。
