Risk Assessment and Environment Management

1. RISK ASSESSMENT AND ENVIRONMENT MANAGEMENT Nano Science & Technology Consortium

4. Assessments completed for about 10 cities and regionsNano Science & Technology Consortium

5. Environmental Management Comparative Health Risk Assessment is used to set priorities for environmental management. Identify and evaluate risks, set priorities among problems. Risk Assessment Develop and implement solutions for high priority problems Risk Management Nano Science & Technology Consortium

6. Environmental Risks Environmental damage may have three types of negative effects. Public Health--illness, injuries, deaths Ecological--loss of species and habitat Quality of Life--economic and social costs Nano Science & Technology Consortium

7. Types of “Risk Assessment” Health Risk Assessment: evaluates the potential public health impacts of an environmental condition Comparative Health Risk Assessment: evaluates and compares the potential health impacts of several environmental conditions Comparative Risk Assessment: evaluates and compares the potential health, ecological, and quality-of-life impacts of several environmental conditions Nano Science & Technology Consortium

9. Steps in Risk Assessment Exposure Assessment-- estimate a group’s exposure (amount, duration) Risk Characterization-- estimate the probability and severity of effects Nano Science & Technology Consortium

11. 300 - 1400 deaths Nano Science & Technology Consortium

12. Example:Health Risk Assessment Health Risk Assessment in Quito, Ecuador: Population: 1.1 million Pesticides in food: 44.3 g/day intake of heptachlor 11.0 g/day intake of aldrin Health Effects: 0.3 to 9.1 x 10-3 lifetime cancer risk Up to 150 excess cancer cases/year Nano Science & Technology Consortium
