Which of the following statements about dose-response curves is FALSE? A)A dose-response curve shows the effect of different doses of a toxicant on a population. B)Doses lower than the threshold level will have no measurable effect on organisms. C)The smaller the LD₅₀, the more toxic the chemical. D)Studies of the dose-response curves of toxicants gives us assurance that for all chemicals there is a threshold level of the chemical so small amounts of chemical pollution pose no health risks

Question

Quizplus · Accepted Answer

The statement D is false because it oversimplifies the complexity of toxicological responses and assumes a universal threshold for all chemicals, which is not accurate. Not all chemicals have a clear threshold below which there are no health risks, as individual sensitivity and long-term low-dose exposures can still pose risks.
