What health issues can sulfur dioxide and oxides of nitrogen cause?

Sulfur dioxide and oxides of nitrogen are significant air pollutants that primarily affect the respiratory system. When inhaled, these gases can irritate the airways and lung tissue, leading to a range of respiratory problems. This includes conditions such as asthma, bronchitis, and other chronic lung diseases. Both sulfur dioxide and nitrogen oxides can aggravate existing respiratory conditions, making it critical to assess air quality in relation to public health.

While heart disease can be influenced by air quality and pollutants, the direct association with sulfur dioxide and oxides of nitrogen is stronger with respiratory health. Skin irritation and visual impairment are not the primary concerns linked to these specific pollutants, as they primarily harm individuals through inhalation and exposure to the lungs rather than through contact with skin or direct effects on vision. Therefore, the focus on respiratory problems highlights the primary health risks posed by these emissions.
