报告人简介： 徐向荣，女，中国科学院南海海洋研究所研究员，博士生导师。研究方向为海洋环境地球化学，探索自然变化和人类活动影响下的污染物（氮磷、重金属和持久性有机物）在典型热带河口及海湾等近海生态系统中的环境过程。2005年获香港大学博士学位后，分别在香港大学和香港理工大学从事博士后研究工作。2010年进入南海海洋研究所工作。先后主持或参加10多项国家或省部级科研项目。目前主持国家自然科学基金面上项目、973项目子课题、广州市科技项目等，参加广东省自然科学基金重点项目。已在国际国内重要学术期刊上发表论文100多篇，其中在Science of the Total Environment, Environmental Research, Chemosphere, Journal of Hazardous Materials, Marine Pollution Bulletin等国际SCI期刊上发表学术论文60多篇，被SCI总引1400多次，H指数20。获得2014年中国科学院广州教育基地优秀研究生导师称号 。

研究领域  以南海及其邻近热带海域为研究区域，以促进热带海洋生物资源可持续利用为主线，以维护和保障近海海域生态安全及促进人类健康可持续发展为目标，组建了“海洋环境污染与生态修复技术”研究团队。试图从环境污染和生态修复两个角度，剖析南海及其邻近热带海域环境污染特征，探索建立环境友好型的复合污染绿色修复技术，尝试构建“环境污染特征-污染源解析-风险评价-绿色修复技术”链式知识体系：

1. 污染物的海洋环境地球化学过程   研究典型污染物在海洋环境介质中的来源及分布特征，阐明污染物在典型海洋生态系统中的传递过程、累积规律及生态效应，为海洋环境污染的预防和治理提供科学基础。

2. 污染修复   研发海洋污染修复技术，耦合物理吸附、化学氧化还原和生物吸附降解等综合技术，为海洋环境污染综合防治提供技术支持。
