FIFTH NHEERL SYMPOSIUM FLYER -- INDICATORS IN HEALTH AND ECOLOGICAL RISK ASSESSMENT
BarnesMiller, A. FIFTH NHEERL SYMPOSIUM FLYER -- INDICATORS IN HEALTH AND ECOLOGICAL RISK ASSESSMENT. U.S. Environmental Protection Agency, Washington, DC.
Announcement for NHEERL Fifth Symposium - Indicators in Health and Ecological Risk Assessment. The purpose of the symposium is to address assessment of risk to public health or environmental resources which requires competent characterization of stressors and corresponding effects. Because of the complexity of most stressor-response relationships, it is impossible to completely characterize all the variables, so a select set of measurements is made to reflect the most critical comonents. Such measurements, or indicators, are included in monitoring programs to estimate trend, stressor source, or magnitude of effects and lead to thresholds for management action or restoration. Although a wide variety of programs and program objectives exist, there are some common challenges for indicator development, including a strong link to management actions. Indicator measurements used in U. S. EPA risk assessment activities must stem from collaboration among managers, risk assessors, scientists and stakeholders. The primary objective of the U.S. EPA's Fifth Symposium of the National Health and Environmental Effects Resarch Laboratory is to improve health and ecological risk assessment through dedicated sessions that maximize interaction and discussion among these groups.
