What does the saying "the dose makes the poison" mean?Multiple choice question.All substances have equivalent potential for harm, so exposure to any of them is risky.Any amount of a dangerous substance is unacceptable and counting the numbers of compounds detected is a reliable way to establish danger.Most substances are toxic at some level of exposure depending on the substance and the nature of the exposure.What matters is the amount of a toxic substance present; whether or not we are exposed to the toxin is not relevant.Need help?

Select all that applyIn assessing the danger of toxic substances, which of these statements are true?Multiple select question.Any exposure to toxic substances is unjustifiable.The dose makes the poison.Our increasing ability to detect traces of a substance sometimes means that though we can detect it, the level may be too low to cause harm.If a toxin can be detected, it is dangerous, no matter how low the level.Need help?

Which of the statements below accurately captures the relationship between toxicity and potency?Multiple choice question.Though categorizing toxins based on potency is useful, it is complicated by differences in individual and species reactions to particular chemicals.Studies of relative toxicity show that while synthetic toxins are very potent, natural toxins have low potency and are toxic only in large doses.The potency of toxins varies, but knowing the level at which a substance is directly toxic makes it possible to establish safe levels for exposure.Need help?

Dose limits are established, above which there is an unacceptably high risk biological damage from exposure. Below the dose limit there is no danger of an exposure causing cancer. True or false?Group of answer choicesTrueFalse

Poisons that are produced naturally are called substances.

Acute toxicity occurs after: Repeated and/or prolonged exposures Single or short exposures Following exposure to a hazardous chemical Exactly 3 exposures
