Which group is likely to have the most extreme reaction to toxic exposure?

Children are likely to have the most extreme reaction to toxic exposure due to their developing bodies and unique physiological characteristics. Their metabolism and organ systems are not yet fully mature, which means they might absorb, metabolize, and excrete toxic substances differently than adults.

Additionally, children have a higher surface area to volume ratio compared to adults, which can lead to greater exposure to certain environmental toxins relative to their body size. Their developmental stages often make them more vulnerable to the adverse effects of toxic substances, such as neurological impacts, because their brains and bodily systems are still forming.

Moreover, children's behavior—such as being more likely to put objects in their mouths, playing close to the ground, and spending more time outdoors—can increase their potential for exposure to hazardous materials. Therefore, this combination of physiological characteristics and behaviors makes children particularly sensitive to toxic exposure compared to other groups like adults, teenagers, or the elderly.
