作者:    信息来源:    发布时间: 2021-03-18

化学品暴露风险分析研究室,主要从事有毒化学品的环境暴露分析以及环境风险评估研究。近5年承担国家自然科学基金项目、国家高技术研究发展计划(863)项目及其它各类科研项目20余项。在“Environ. Sci. Technol.”等高水平期刊发表SCI论文70余篇,申请发明专利9项。

研究方向:(1) 新型及痕量环境污染物的分析;(2)有毒污染物快速分析新方法、新技术;(3)有机污染物的环境光化学行为;(4) 有机污染物环境迁移转化研究。

The research works of Chemical Exposure Risk Analysis Group mainly focus on the analysis and assessment of the contamination levels, environmental fate and risks of toxic chemicals. During the last five years, the group has carried out over 20 national and other projects, published over 70 SCI-indexed papers and applied for 9 invention patents.

The main research fields include: (1) Analysis of novel and trace environmental pollutants; (2) New methods and techniques for fast detection of toxic pollutants; (3) Environmental photochemical behavior of organic pollutants; (4) Environmental fate of organic pollutants.

代表性成果


——水体中藻毒素的免疫传感检测方法

发展了一种基于单壁半导体碳纳米管的无标记免疫电阻传感器,用于水中痕量微囊藻毒素的快速检测。该方法不需要任何标记步骤、灵敏度高、选择性好,整个分析过程可在1 h内完成,具有重要应用前景。





——羟基多溴联苯醚(OH-PBDEs)在非生命介质中的来源及形成机制

以天然水中的典型溴酚为模型化合物,研究了水体中OH-PBDEs的光化学形成,通过采用激光闪光光解技术,从分子水平研究了该转化过程的反应路径及基元反应动力学,结合电子顺磁共振技术详细表征转化过程中产生的活性物种,揭示了苯氧自由基共振式的二聚反应是水体中溴酚光聚生成OH-PBDEs的反应机制。
