3. amount that is present

- risk characterization
chemical exposure
-carbon monoxide

environmental health history
amount of exposure to an environmental risk varies based on proximity
-time and location
older adults environmental health
-increased age
-chronic conditions
-increase risk environmental hazards
-higher burden of absorbed chemicals
environmental health nurses
