| The lungs also contribute to this process by eliminating carbon dioxide which is the waste byproduct of glucose and lactic acid metabolism. |
| Figures showed that amounts of the pollutant nitrogen dioxide were predicted to exceed allowed annual limits in five areas of the city. |
| Volcanic carbon dioxide would cause atmospheric warming that would, in turn, warm surface ocean water. |
| Additionally, carbon dioxide and organic acids may be added to the water from the soil, where they form by decay of organic matter. |
| The gases, especially carbon dioxide and methane, absorb the Earth's heat radiation and thus warm the surface, just as a blanket traps body heat. |
| Researchers say many sodas are acidic and contain carbon dioxide that can expand the stomach, which in turn can cause acid reflux. |
