Ecological Risk Assessment

An ecological risk assessment is the process for evaluating how likely it is that the environment may be influenced as a result of revelation to one or more environmental stressors like chemicals, land change, disease, invasive species and climate change. Environmental Risk Assessment (ERA) aims to evaluate the effects of stressors, generally chemicals, on the specific environment. A risk is an integrated evaluation of likelihood and severity of an unsought event. In ERA, the unsought   event often depends on the chemical of interest and on the risk assessment scenario.
