However, it is possible that exposure to certain microorganisms and other biological contaminants can cause serious, potentially life threatening respiratory diseases that may lead to chronic respiratory ailments.
  • Chronic effects. Chronic effects are long-lasting responses to long-term or frequently repeated exposures. Cancer is the most well-known chronic effect of long-term exposure to certain air pollutants.
