What does exposure to formaldehyde primarily irritate?

Exposure to formaldehyde primarily irritates the respiratory passages. Formaldehyde is a volatile organic compound commonly found in a variety of building materials and household products. When inhaled, it can lead to irritation in the mucous membranes of the respiratory system, causing symptoms such as coughing, wheezing, and shortness of breath. The irritation occurs because formaldehyde can react with the tissues in the respiratory tract, leading to inflammation.

While formaldehyde can also cause irritation of the eyes and skin upon direct contact, the most significant and common health effect associated with exposure is on the respiratory system. This makes it essential for environmental health specialists to be aware of the risks associated with formaldehyde exposure, especially in settings with inadequate ventilation. Understanding this is crucial for implementing safety measures and promoting public health.
