Does bonfire make the air pure or impure?

A bonfire can make the air impure due to the release of smoke and particulate matter, which can contain harmful pollutants and contribute to air quality issues. The combustion of wood and other materials produces carbon monoxide, volatile organic compounds, and other toxins. While a bonfire can create a pleasant atmosphere, it's essential to consider its impact on air quality and respiratory health, particularly for sensitive individuals. Overall, the air around a bonfire is generally considered to be less pure.
