What common issue can formaldehyde from building materials cause?

Formaldehyde, a volatile organic compound commonly found in various building materials, such as pressed wood products, glues, and insulation, can lead to respiratory issues when it is released into the indoor air. People who are exposed to elevated levels of formaldehyde may experience a range of health problems, particularly affecting the respiratory system. Symptoms can include irritation of the eyes, nose, and throat, as well as more serious conditions such as coughing, wheezing, and aggravation of asthma or other chronic lung conditions.

This is especially concerning in poorly ventilated spaces where formaldehyde can accumulate, leading to prolonged exposure. The impact of formaldehyde on respiratory health is well documented, making it a significant concern for indoor air quality and public health. Understanding this connection is crucial for environment health professionals and sanitarians, as it helps them address potential health risks in buildings and ensure safer environments for occupants.

While the other options could relate to various building concerns, they do not have a direct association with the health consequences linked to formaldehyde exposure. For instance, increased humidity levels may occur for different reasons, electrical malfunctions relate more to wiring issues, and insect infestations are typically caused by poor sanitation practices or structural problems.
