the lungs by normal pulmonary clearing mechanisms. Because of these factors, we do not expect members of sensitive populations to have greater harmful effects from exposure to zinc cadmium sulfide. However, as a precautionary measure, the subcommittee assumed in its risk estimates for cancer and other health effects that sensitive subpopulations might be 10 times more sensitive than healthy adults.
9. Would there be any potential adverse health effects passed on to children born to people who were exposed to zinc cadmium sulfide?
The subcommittee did not identify any information showing that exposure to zinc cadmium sulfide could have caused adverse health effects in the children of exposed people. The subcommittee's review of available developmental toxicity data on cadmium (the most toxic component of zinc cadmium sulfide) shows that it is extremely unlikely that children of exposed mothers would show signs of developmental toxicity at the low levels encountered as a result of the Army's dispersion tests.
10. How do I know if I have been exposed to zinc cadmium sulfide?
No medical test is available to determine whether you were exposed to zinc cadmium sulfide. However, you can be tested for exposure to cadmium in several ways. The amount of cadmium in your blood, urine, hair, or nails can be measured by some medical laboratories. The amount of cadmium in your blood tends to show your recent exposure to cadmium. The amount in your urine tends to indicate both your recent and past exposures. However, a finding of exposure to cadmium does not mean that you were exposed to zinc cadmium sulfide, because people are exposed naturally to cadmium from air, food, and water. The subcommittee concluded that an increase in cadmium in the body above the typical background concentrations could not be attrib-
