WHAT TYPES OF RISK ARE EVALUATED IN AN MMR ECOLOGICAL RISK ASSESSMENT?
The types of stressors evaluated in an MMR ecological risk assessment include those posed by chemical contamination and physical changes (such as habitat destruction). Ecological effects on selected plants and animals, such as changes in growth, ability to produce offspring, or death, also may be evaluated in the ecological risk assessment.
