What is usually associated with repeated exposure over a longer period causing toxicity?

Chronic toxicity is characterized by the harmful effects that result from prolonged or repeated exposure to a toxic substance over a significant period. This may involve continuous or frequent exposure, even at lower doses, which can lead to gradual and cumulative harmful effects on various organ systems. Unlike acute toxicity, which typically arises from a single high-dose exposure resulting in immediate adverse effects, chronic toxicity develops over time and often leads to long-term health issues.

Chronic toxicity is often associated with substances such as certain heavy metals, solvents, or medications, where daily exposure may not produce immediate symptoms but can lead to serious health consequences such as organ damage, cancer, or other chronic diseases after many years of exposure. This ability to cause harm over extended periods is a fundamental aspect of chronic toxicity, highlighting the importance of monitoring and regulating exposure to potentially harmful substances in both occupational and environmental settings.
