| 1 | One of the constituents of both smoke and urban pollution is carbon monoxide. | |
| 2 | Finally, the map shows high carbon monoxide concentrations along the Atlantic Seaboard. | |
| 3 | Emissions of greenhouse gases, carbon monoxide and particulates could all be significantly reduced. | |
| 4 | That produces hydrogen and carbon monoxide, which can be converted to a liquid fuel. | |
| 5 | Besides water, the plume also contained carbon monoxide, carbon dioxide, ammonia, sodium, mercury and silver. |
