Which of these factors should NOT be included in determining sensitivity to chemicals?

When assessing sensitivity to chemicals, factors such as tobacco use, pregnancy, and general health are all significant because they can increase the potential for adverse reactions to various substances.

Tobacco use can compromise lung function and overall health, making individuals more vulnerable to respiratory irritants found in many chemical products. Pregnancy is a critical period where hormonal changes and increased susceptibility to toxins can affect both the mother and developing fetus. General health encompasses an individual’s medical history, pre-existing conditions, and immune responses, all of which contribute to how the body reacts to chemicals.

Income level, in contrast, might influence access to healthcare and products but does not directly affect an individual’s physiological sensitivity to chemical substances. Therefore, it is appropriate to exclude income level from the factors considered in determining sensitivity, as it does not have a direct biological impact on how the body processes or reacts to chemicals.
