When dealing with a hazardous material exposure, what time frame is considered long-term?

Long-term exposure to hazardous materials is typically defined as an exposure that lasts for years or even generations. This duration indicates a sustained interaction with a hazardous substance, which can lead to cumulative health effects, chronic illnesses, and environmental impacts. Unlike short-term exposure, which may result in immediate, acute reactions, long-term exposure allows hazardous materials to accumulate within the body or environment, leading to progressive health risks. Understanding the significance of long-term exposure is crucial in emergency response and public health planning, as it influences monitoring strategies, remediation efforts, and health screenings for affected populations.
