Which term describes a delayed poisonous effect from exposure to a substance?

The term that describes a delayed poisonous effect from exposure to a substance is chronic toxicity. This refers to the adverse effects that occur after prolonged exposure to low levels of a toxic substance over time. Unlike acute toxicity, which results from short-term exposure and manifests rapidly, chronic toxicity is characterized by symptoms and health issues that may take longer to develop, often showing up after repeated exposure over extended periods. This is particularly relevant in environmental health and pesticide exposure, as it helps determine long-term risks associated with certain chemicals. Understanding chronic toxicity is crucial for safety practices in pesticide application and for evaluating the impact on both human health and the environment.
