Exposures and Risk
You can be exposed to environmental health hazards in one of three ways: swallowing (ingestion), breathing (respiration), or skin contact (absorption). How dangerous the exposure is can be affected by:
- The way that you are exposed: Touching a sponge containing a toxic cleaning product may not be too big a problem, but accidentally swallowing the same product could be extremely dangerous.
- The amount of the exposure: Being exposed to a larger quantity of a toxic substance can be much more harmful than exposure to a smaller quantity.
- The frequency of the exposure: Being exposed to a toxic substance on a regular basis can be more harmful than a single or rare exposure.
- Your age, your overall health, and your genes: Some people's bodies are better able to deal with exposure to a health hazard. Because fetuses and children are small and still developing, they are particularly vulnerable.
Consider the three health hazards you listed on the previous screen. Describe how the above factors might affect how dangerous your exposure could be. Be sure to click "Save."
