2. Goals • What is an environmental problem? Evolving issues • Recognition, understanding, judging, action • Measurements, mathematics and statistics • If mathematics is the language of nature then statistics is its dialects • Classification of environmental problems • Extent: Global, regional, local; duration • Type: Natural or anthropogenic • Effects: Lethal or chronic, significant or insignificant, social, political, ecological risks • Some Typical Examples • Water Pollution Risks 4. Needs • Collaboration among stakeholders • Ecological and environmental indicators • Improved predictive, tools for risk analysis

3. Balance between Growth and Environmental Health Balance between the Present and the Future Land, Water, Air Environment Environmental Quality Natural Resources Economy Labor Force Human Production Consummation Capital Innovation Quality of Human Life Waste Pollution

13. INTERPRETATIONOF RISK TERMS • Risk: undesirable outcomes which differ from the beneficial ones • Analysis in isolation is difficult due to inextricable association with the beneficial ones. • They are not mutually exclusive!  Decision-making is based on the level of disbenefits and risk we may choose to tolerate, compared to the benefits of the outcomes.

14. encompasses a number of concepts and methods directed towards gaining qualitative and quantitative understanding of risks. focuses on the knowledge about the nature and burden of risks involved in an activity and placing it in some framework of relationships to express its significance. concerns with arrangements to deal with the assessed burden of risk by eliminating causes of risk where practicable; reducing the probability of occurrences and the magnitude of consequences; seeking acceptable compensations and redistributions in relation to the residual risk (i.e., Don’t keep all the eggs in one basket!). PRINCIPAL CONCEPT OF RISK Interactive and Complementary RISK ASSESSMENT RISK MANAGEMENT

15. Components of Risk Communication

16. Setting Regulations

17. Risk & Benefit (Health & Economy)

18. Objectives of Environmental Effects Monitoring Program: • Does effluent cause an effect in the environment? • Is effect persistent over time? • Does effect warrant correction? • What are the causative stressors? • From 1992, all new effluent regulations require sites to do EEM. • Pulp and Paper Pilot program
