What is the general effect of chronic exposure to toxic substances?

Chronic exposure to toxic substances typically leads to slowly developing harmful effects. This occurs because the body may initially tolerate low levels of exposure without showing immediate symptoms. Over time, however, the accumulation of toxins can disrupt normal physiological processes and lead to a range of health issues, including chronic diseases, organ damage, or cancer.

In contrast to the other options, which suggest immediate or non-existent impacts, chronic exposure is characterized by a gradual onset of symptoms that can be subtle at first but progressively worsen. It is essential for individuals who might be exposed to toxic substances over extended periods to be aware of these potential long-term health implications, as they may not recognize the risks right away.
