What type of respiratory issue is linked to sulfur dioxide exposure?

The connection between sulfur dioxide exposure and respiratory issues is significant, especially concerning lower respiratory tract irritation. Sulfur dioxide is a gas that can exacerbate pre-existing respiratory conditions and irritate the airways. When inhaled, it reacts with the moisture in the respiratory tract, forming sulfurous acid, which can lead to inflammation and irritation in the lungs.

This irritation can result in symptoms such as coughing, wheezing, and shortness of breath, particularly affecting individuals with asthma or chronic obstructive pulmonary disease (COPD). When the lower respiratory tract is compromised, it can result in more severe respiratory issues and has been associated with increased respiratory distress in sensitive populations.

Understanding the specific impact of sulfur dioxide allows industrial hygienists to implement appropriate control measures to protect workers and individuals in areas where sulfur dioxide might be present, thus mitigating risks to health and safety.
