报告人简介：
Dr. Joan Rose serves as the Homer Nowlin Chair in Water Research at Michigan State University, the Co-Director of the Center for Advancing Microbial Risk Assessment (CAMRA) and the Director of the Center for Water Sciences (CWS). Dr. Rose received her B.S., in 1976 from University of Arizona, her MS from University of Wyoming in 1980 and Ph.D. in Microbiology from the University of Arizona in 1985. She served as a Professor in the College of Marine Science, University of South Florida (USF) from 1998-2002 and Associate Professor, Department of Marine Science, USF from 1994-1997. In 1995, she was an Assistant Professor, Department of Environmental and Occupational Health, USF, and from 1986-1989, she served as Research Associate/Lecturer, Department of Microbiology and Immunology, UAZ.
Abstract：
Prevention and control of infectious diseases requires an understanding of the ways bacteria, viruses and parasites are spread. Environmental transmissible agents such as waterborne pathogens are particularly a challenge due to the emergence of viruses and parasites which are resistant to conventional means of water and wastewater treatment. Knowledge of the transmission systems [including transport and survival] of many potential agents is incomplete; thus we need to greatly enhance the ability to effectively predict and anticipate the extent of an epidemic following a water contamination event, and develop management strategies for control. Quantitative microbial risk assessment (QMRA) is now a field which has developed over the last decade and is used to address both probability of infection and community risks. The new challenges facing the development of a strategy for achieving community goals of for water quality and water safety require that greater specificity regarding the infectious agent is addressed and that better assessment of exposure is undertaken. Methodologies associated with sampling [e.g. air, water, and surfaces] will need to take into account the level and extent of exposure and be able to interpret this in regard to health outcomes. Future advances will focus on models of the agent and its transmission as well as analytical methods using environmental and epidemiological data. The use of QMRA can be used to set priorities for improving the safety of water and for setting relevant public policy. Many examples of QMRA applications are available from defining drinking water treatment to assessing sewage treatment and reuse. While the conventional National Academy of Sciences approach (4 steps Hazard Identification, dose-response, exposure assessment and risk characterization) will continue to be used, new tools and techniques as well as the issues of sensitive populations will likely modify the risk assessment strategy for microbial contaminants.
