| A screening-level human health risk assessment model, MUM-FAMrisk, was developed to quantify risk of adverse human health effects, with the aim of supporting environmental decision-making. MUM-FAMrisk is comprised of exposure assessment and risk characterization components and can assess cancer and non-cancer risk from exposure to organic contaminants and metals for seven human life stages. Model flexibility allows for a combination of modelled and measured model input data. MUM-FAMrisk is used as a baseline scenario to compare six international approaches to screening-level risk assessment, which serves to highlight variability between exposure and risk estimates. Model features and utility are demonstrated in its application to mobile and area sources of polycyclic aromatic hydrocarbons from the Greater Toronto Area, Ontario, Canada. |
