Not all combustion products are toxic, but many can be harmful to human health and the environment. For example, carbon monoxide is a toxic gas produced during incomplete combustion of carbon-containing fuels. Additionally, nitrogen oxides and volatile organic compounds produced during combustion can contribute to air pollution and have negative health effects. However, some combustion products, such as carbon dioxide and water vapor, are not inherently toxic to humans. **
