Provides QMRA methodologies to determine infection risk cause by either accidental microbial infections or deliberate infections caused by terrorism. This title reviews methodologies to quantify at every step of the microbial exposure pathways, from the first release of a pathogen to the actual human infection.
Provides the latest QMRA methodologies to determine infection risk cause by either accidental microbial infections or deliberate infections caused by terrorism
• Reviews the latest methodologies to quantify at every step of the microbial exposure pathways, from the first release of a pathogen to the actual human infection
• Provides techniques on how to  gather information, on how each microorganism moves through the environment, how to determine their survival rates on various media, and how people are exposed to the microorganism
• Explains how QMRA can be used as a tool to measure the impact of interventions and identify the best policies and practices to protect public health and safety
• Includes new information on genetic methods
• Techniques use to develop risk models for drinking water, groundwater, recreational water, food and pathogens in the indoor environment

Charles N. Haas is the head of the department of Civil, Architectural and Environmental Engineering at Drexel University and the Betz Chair Professor of Environmental Engineering.  He has served on numerous advisory committees of the US EPA and the National Research Council 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).  She is a member of the National Academy of Engineering. Charles P. Gerba is a Professor in the department of Soil, Water and Environmental Science at the University of Arizona. He is the author of 11 books and over 400 journal papers. Dr. Gerba is a member of the U.S. Environmental Protection Agency's Science Advisory Board Committees on Drinking Water and Research Strategies.
