Modelling the public health risks associated with environmental exposures: A case study in wastewater reuse

摘要

This project used a novel, probabilistic approach to overcome challenges of assessing health risks associated with recycled water. The thesis describes development of graphical statistical models combining key factors influencing risk of infection. The models were used to analyse exposure scenarios and risk management options for working or playing in public parks irrigated with recycled water and for consumption of recycled water-irrigated lettuce. Water managers can use the models interactively to vary exposure factors and assess outcomes of their decisions under different conditions.
