Question

question 7
acute exposure to an environmental toxin
o is the case with chronic alcohol and nicotine abuse
o involves low levels of exposure over long periods of time
o is a high exposure over short times and associated with a specific cause
o makes it difficult to associate the symptoms with a cause
o is usually untreatable and fatal

Explanation:

• Chronic alcohol and nicotine abuse: These are examples of chronic exposure (low - level over long time), not acute.
• Low levels over long periods: This is the definition of chronic exposure, not acute.
• High exposure over short times: Acute exposure is characterized by a high - dose exposure in a short time frame, and it is often associated with a specific incident (e.g., a chemical spill at work).
• Difficulty associating symptoms with cause: This is more of a characteristic of chronic exposure where the build - up of a toxin over time makes causation harder to pinpoint.
• Usually untreatable and fatal: Acute exposure is not always untreatable and fatal. For example, acute carbon monoxide poisoning can be treated with hyperbaric oxygen therapy.

Answer:

is a high exposure over short times and associated with a specific cause
