Exposure to environmental toxins can lead to a range of health issues, depending on the nature of the toxin and the level of exposure. Short-term exposure to high levels of pollutants can cause acute effects such as respiratory distress or skin irritation. Long-term or chronic exposure can lead to more severe health problems, including cancer, neurological disorders, and endocrine disruption. Vulnerable populations, such as children and pregnant women, may be more susceptible to these effects.
