Sulfur dioxide and oxides of nitrogen are primarily known as pollutants produced from burning fossil fuels and industrial processes. When these gases are inhaled, they can irritate the airways and lead to respiratory problems. This includes conditions such as asthma, bronchitis, and other chronic respiratory diseases, which are worsened by exposure to these pollutants.

The respiratory tract is particularly sensitive to these gases, as they can cause inflammation and aggravate existing lung conditions. The presence of these substances in the air contributes to poor air quality, which has been linked to increased hospital admissions for breathing difficulties and other respiratory issues.

Other options, such as bone fractures, skin irritation, and vision impairment, are generally not associated with exposure to sulfur dioxide and oxides of nitrogen in the same way that respiratory issues are. While skin irritation could occur from exposure to certain chemicals, it is not a major health risk linked to these specific pollutants.
