Question

Quizplus · Accepted Answer

LD₅₀ values refer to the dose of a chemical that is lethal for 50% of the population that is exposed to it. Research has shown that children are more susceptible to chemical exposure than adults, and the LD₅₀ values are lower for children than adults. Option A is incorrect because children are actually more susceptible to chemical exposure than adults. Option C is incorrect because LD₅₀ values are affected by variables such as age, sex, weight, and overall health. Option D is incorrect because the ED₅₀, which refers to the dose of a chemical that has an effect on 50% of the population that is exposed to it, can also be different for children compared to adults.
