emissions, eg dust and other substances to the air. hazardous substance storage, use and disposal. liquid waste drainage and disposal. environmental impact of raw materials, eg potentially toxic metals or other materials.
Why is an environmental risk assessment required?
Environmental risk assessments require determination of risks for physiologically diverse individuals who are exposed to several air and water pollutants. … Because a chemical may produce more than one toxic effect, the first step for these assessments is to identify the adverse effect that occurs at the lowest dose.

- Step 1 – Hazard Identification. …
- Step 2 – Dose-Response Assessment. …
- Step 3 – Exposure Assessment. …
- Step 4 – Risk Characterization.
What are the 3 types of risk factors?

What are the 4 types of environmental hazards?
Types of Environmental Hazards
To better understand them, we can think of them as falling into four categories: physical, chemical, biological, and cultural. Physical hazards are physical processes that occur naturally in the environment.
