Ecological Risk Assessment Framework
The framework of ecological risk assessment consists of a problem statement (formulation), risk analysis, risk characterization, and risk management. A precursor to the problem statement involves a historical account and fundamentals of living organisms, ecological systems, and any substances, whether biological or synthetic, that may be introduced to environmental components. Once evaluated, a problem statement can be defined and a plan created to analyze and characterize the risk. Reviewing data on sources, stressors, effects, and ecosystem and receptor characteristics helps to develop endpoints and conceptual models that are used to complete an analysis plan (2002). The analysis plan is used to determine how stressors occur and how exposure to stressors may occur; these are characterization profiles that lead to risk characterization. Risk characterization integrates exposure and stressor-response profiles to summarize assumptions, uncertainties, strengths, and limitations of analysis (2002). Risk assessors communicate the results to risk managers. Risk management consists of evaluating data from all aspects, reiterating or changing assessment activities, and reviewing data pertaining to predictions and endpoints to determine a feasible outcome; considering risks and interested and affected parties.
Framework Correlation
The problem statement correlates to the analysis through the formulation of endpoints and conceptual models, which is used in the analysis process to determine exposure characterization and effects characterization (2002). The exposure and effects characterization are used in the risk characterization, which integrates the profiles and sums up a risk description of adverse effects, uncertainties, and supporting information. Risk assessors then communicate data to risk managers, who determine potentiality of
