Washington Pesticide Laws and Safety Practice Test

When we talk about acute toxicity, we are referring to the immediate or short-term effects that occur after a single exposure to a substance. This can include symptoms such as nausea, vomiting, and dizziness. Option A is incorrect as it refers to the effects from long-term exposure, which would fall under the category of chronic toxicity. Option C is incorrect as it refers to genetic changes over time, which is not necessarily related to acute toxicity. Option D is incorrect as it refers to the development of tumors, which would fall under the category of carcinogenicity, a different type of toxic effect. Therefore, option B is the best answer as it accurately describes the characteristics of acute toxicity.
