What is acute toxicity?

1. Long-term exposure to chemicals

2. Immediate effects from a short exposure

3. Gradual long-term health effects

4. High dose resistance

The correct answer is: Immediate effects from a short exposure

Acute toxicity refers to the immediate harmful effects that result from short-term exposure to a substance, often at high doses. This form of toxicity can manifest rapidly after the exposure, leading to significant health impacts that may require urgent medical attention. Common examples include reactions to poisoning from chemicals, where symptoms can arise within minutes or hours of exposure. Unlike long-term exposure, which is associated with chronic toxicity and gradual health deterioration over time, acute toxicity emphasizes the sharp and instant reactions that can occur. This concept is crucial in safety and health assessments, particularly in industries where workers may encounter hazardous substances. Understanding acute toxicity helps in implementing immediate protective measures and responses in case of chemical accidents.
