What are effects that may be exhibited years after exposure?

Long term health effects refer specifically to the consequences of exposure to a substance or environmental factor that manifest after a significant period, often extending to years or even decades later. These effects can develop insidiously, meaning that the health issues may not be immediately apparent following exposure. For instance, long term health effects can include a range of conditions such as cancer, respiratory diseases, and other chronic illnesses that may arise from prior exposure to harmful substances or environmental conditions.

In the context of this question, the emphasis is on the time frame of manifestation of health effects, which is why long term health effects are the most appropriate answer. These refer to serious health consequences that linger long after the initial exposure has occurred, highlighting the importance of monitoring and understanding potential risks associated with previous exposures.

Other effects, such as temporary and acute effects, typically present shortly after exposure and do not capture the prolonged timeline indicated in the question. Chronic effects, while they could be considered long-lasting, are often understood to have ongoing symptoms rather than manifesting after years of latency.
