What can prolonged exposure to biological contaminants result in?

Prolonged exposure to biological contaminants, such as mold, bacteria, and allergens, can lead to a variety of health problems. These issues may include respiratory infections, asthma, allergic reactions, and other serious conditions, particularly in sensitive individuals, such as those with preexisting health issues or weakened immune systems. Biological contaminants can thrive in damp or poorly ventilated areas, and their presence can significantly degrade indoor air quality. Understanding the implications of these contaminants is crucial for maintaining a healthy environment, as prolonged exposure can have lasting effects on both physical health and overall well-being.

The other options do not effectively capture the significance of biological contaminants in relation to indoor environments. For instance, increased property value is more likely associated with well-maintained properties, rather than those plagued with contamination. Enhanced air quality contradicts the impact of biological contaminants, which typically degrade air quality rather than improve it. Lastly, improved insulation is not a direct consequence of exposure to biological contaminants and may lead to an environment that traps moisture and exacerbates contamination issues.
