| Sumario: |
Risk assessment is the process by which the probability and magnitude of adverse effects is evaluated as a result of exposure to one or more stress factors. Risk assessment can be used to predict, compare, and manage environmental risk, and provide a quantitative basis for preventive or remedial action under uncertainty. This work attempts to integrate ecological , and human health risk assessments to mercury emissions in a small scale gold mining area. The relative risk of damages to stream biota, and local inhabitants, was calculated using hazard quotient (HQ) approaches. When comparing our results a relatively higher risk from Hg emission is found for human health followed by aquatic organisms. |
