Which of the following factors can affect a person's sensitivity to a chemical?

A person's sensitivity to a chemical can indeed be influenced by gender due to biological and physiological differences. These differences can affect how chemicals are absorbed, distributed, metabolized, and eliminated in the body. For instance, hormones and body composition can lead to variations in how men and women respond to certain substances, which can impact the level of toxicity or effectiveness of those chemicals.

While other factors like occupation, height, and the type of chemical may also play roles in an individual’s overall exposure risk or sensitivity, gender specifically encompasses inherent biological factors that can directly influence chemical reactions within the body, making it a significant factor in understanding sensitivity to chemicals.
