Subacute lethality refers to toxic effects that occur after repeated exposure to a substance over a period of days to weeks, usually up to one month. It is an intermediate category of toxicity that falls between acute toxicity, which occurs after a single or short-term exposure, and chronic toxicity, which involves long-term exposure. Subacute lethality is crucial for understanding the potential danger of chemicals that may not cause immediate death but can be fatal with repeated exposure over a relatively short period.
