Definition Ecological risk assessment

is a process for organizing and analyzing data, information, assumptions, and uncertainties to evaluate the likelihood that one or more stressors are causing or will cause adverse ecological effects. Ecological risk assessment provides risk managers with a tool for considering available scientific information when selecting a course of action, in addition to other factors that may affect their decision (e.g., social, legal, political, or economic). Ecological risk assessment includes three phases (problem formulation, analysis, and risk characterization). Within problem formulation, important areas include identifying goals and assessment endpoints, preparing a conceptual model, and developing an analysis plan. The analysis phase involves evaluating exposure to stressors and the relationship between stressor levels and ecological effects. In risk characterization, key elements are estimating risk through integration of exposure and stressor-response profiles, describing risk by discussing lines of evidence and determining ecological adversity, and preparing a report.
