How can ozone (O3) impact indoor air quality?

Ozone (O3) can significantly impact indoor air quality primarily because it can be produced by certain electrical devices, including photocopiers and electric motors. These devices can create ozone as a byproduct of their operation, especially during processes that involve high-voltage electrical discharges.

Ozone is a reactive gas that can lead to various health issues such as respiratory problems, irritation of the eyes, and exacerbation of asthma. As a result, its presence in indoor environments can contribute to a decline in air quality, making it crucial for individuals in occupational settings to monitor and manage ozone levels to ensure a safe and healthy atmosphere.

The other options do not accurately represent the relationship between ozone and indoor air quality. For instance, ozone does not help reduce dust levels; in fact, it may react with various indoor pollutants rather than mitigate them. Additionally, ozone is not classified as a health-promoting gas; rather, it poses health risks, particularly in sensitive individuals. Finally, saying that ozone has no effect on indoor environments neglects its significant role in affecting air quality and public health.
