Abstract

In recent years, cyanobacterial blooming in lakes and reservoirs is becoming more and more frequent, which has caused serious concerns regarding the drinking water safety posed by harmful algal metabolites such as odor and toxin substances. In this project, two source water reservoirs in north China (Miyun Reservoir and Yanghe Reservoir), which are in different nutrition states, were selected as the research targets, and the responding mechanisms of algae to nutrition and hydraulic conditions, as well as the physical, chemical and biological mechanisms for the production of odor-causing compounds and algal toxins were systematically studied by combining the on-site observation approaches with microcosm simulation methods. By comprehensively using the methodologies of applied ecology, hydraulics, environmental chemistry and molecular biology, this project will try to elucidate the impacts of different environmental factors on the algal population dynamics and harmful algal metabolites both qualitatively and quantitatively, and establish algal ecological dynamics models. The purpose of the study is to predict the occurrence of algal blooms and the production behavior of harmful algal metabolites, and provide a scientific basis for lake and reservoir-type water source management.

My research interest is water quality problems in drinking water bodies, with a focus on harmful algal blooms and associated taste & odor problems.
