The health effects of contaminants depend on their type, concentration, exposure duration, and the susceptibility of the exposed population. Acute exposure to high levels of contaminants can lead to immediate health effects such as poisoning, respiratory issues, and skin irritation. Chronic exposure, even at low levels, can lead to long-term health issues like cancer, neurological disorders, and reproductive problems. For example, lead contamination is known to cause cognitive impairment in children.
