What is the result of repeated exposure to a low dose of a toxic substance over time?

• A. Acute toxicity
• B. Chronic toxicity
• C. Immediate health impacts
• D. No effect

Answer: (B)

Repeated exposure to a low dose of a toxic substance over time typically leads to chronic toxicity. This type of toxicity occurs when a person is exposed to a harmful substance at a low level for an extended period. Unlike acute toxicity, which results from a single high-level exposure leading to immediate health effects, chronic toxicity can result in cumulative harm that may take years to manifest. This can include a range of long-term health effects, including organ damage or the development of diseases such as cancer. Chronic toxicity is particularly concerning in the context of environmental health and occupational safety, as individuals may unknowingly accumulate harmful doses over time, leading to subtle but serious health issues that require monitoring and management.
