What does "at-risk populations" refer to in toxicological assessments?

The term "at-risk populations" in toxicological assessments specifically refers to groups that are more susceptible to the toxic effects of chemicals. This susceptibility can result from various factors, including age, pre-existing health conditions, genetic predispositions, and environmental influences.

For instance, children may have immature metabolic pathways, making them more vulnerable to certain toxins. Similarly, elderly individuals or those with compromised immune systems can also be at greater risk. Identifying these populations is crucial for risk assessment and for implementing appropriate safety measures to protect their health.

In contrast, other options describe groups that are either less susceptible or resistant, which do not fall under the definition of at-risk populations, nor do they encompass the concept of susceptibility to toxic exposures. Additionally, mentioning groups in chemical-free environments does not pertain directly to susceptibility to toxins in assessments relevant to environmental health or toxicology. Understanding the specific characteristics of at-risk populations aids in tailoring public health strategies and regulations aimed at minimizing their exposure to hazardous substances.
