Problem 9: Factors affecting individual susceptibility

For help to answer the question:

All of the people listed below live in the same house. Who is most likely to experience toxic effects from the second-hand smoke?
A. the grandmother, who is very fit
B. the mother, who smokes
C. the father, who smokes
D. the teenage daughter, who has asthma
E. the son, who is in 5th grade


A person's health status can affect their response to a hazard. For example someone with asthma, whose lungs are already experiencing illness, may be more sensitive to hazardous gases and particles in the air. Also, people with damaged livers may be less able to biologically process harmful chemicals and would therefore be more sensitive than someone with a healthy liver.
