Question: 1 / 400

What best defines chronic toxicity?

Toxic effects that appear immediately after exposure

Toxic effects that result from a one-time exposure

Toxic effects that develop after long-term exposure to a substance

Chronic toxicity is characterized by the development of toxic effects that arise from prolonged or repeated exposure to a substance over an extended period, often involving lower doses that might not elicit immediate reactions. These effects can gradually manifest and may not become apparent until long after the exposure has occurred, potentially leading to serious health issues over time. This contrasts with acute toxicity, where effects are typically rapid and occur soon after exposure.

Understanding chronic toxicity is crucial in toxicology, as it can lead to prolonged health effects that may not be initially recognized. This knowledge is particularly important for regulatory frameworks and health assessments related to long-term exposure to chemicals in various settings.
