What Is Sulfur Dioxide and How Does It Affect Indoor Air Quality?
Sulfur dioxide (SO2) is a colorless gas with a pungent smell, produced primarily from burning fossil fuels and industrial processes. It can significantly affect indoor air quality by contributing to respiratory problems and aggravating existing health conditions.
According to the U.S. Environmental Protection Agency (EPA), sulfur dioxide is defined as an air pollutant and can lead to poor air quality both outdoors and indoors. The World Health Organization (WHO) also identifies SO2 as a harmful air contaminant that poses health risks.
Sulfur dioxide can cause various health issues, including irritation of the respiratory system, throat, and eyes. It impacts individuals with asthma or chronic obstructive pulmonary disease (COPD) more severely, leading to exacerbated symptoms.
The National Institute for Occupational Safety and Health (NIOSH) describes sulfur dioxide exposure as a risk in industries such as oil refining and metal smelting, where emissions can infiltrate indoor environments. Poor ventilation and excessive use of combustion appliances can elevate SO2 levels indoors.
Statistics indicate that approximately 1.3 million tons of sulfur dioxide were emitted in the United States in 2020, according to the EPA. Projections suggest that with rising energy demands, emissions could remain significant unless effective measures are implemented.
Continual sulfur dioxide exposure can result in diminished air quality, contributing to long-term health issues like lung diseases. Environmental consequences include acid rain, leading to damage to buildings, ecosystems, and water bodies.
Health impacts include increased respiratory illnesses and costs associated with healthcare and lost productivity. Economically, industries may face heavy fines for emissions violations.
To reduce sulfur dioxide levels indoors, experts recommend improved ventilation, using low-emission appliances, and maintaining indoor air quality. The EPA advises routine air quality monitoring to ensure safe levels.
Specific strategies include using air purifiers equipped with activated carbon filters, conducting regular maintenance on heating systems, and minimizing the use of combustion-based appliances indoors.
