Venus, Earth, Mars, and Triton (Neptune's largest moon) have carbon dioxide in their atmospheres.
It depends on how you define air. Other planets in the solar system have atmospheres, but they have different compositions from Earth's atmosphere, which may or may not be called air. The gas planets have atmospheres made mostly of hydrogen and helium while Venus and Mars have atmospheres made mostly of carbon dioxide. The air we are familiar with is mostly nitrogen and oxygen. When Earth was young it likely had a carbon dioxide atmosphere as well, but through photosynthesis algae took carbon dioxide out of the atmosphere are replaced it with oxygen. More carbon dioxide was removed in bodies of water and deposited as carbonate rocks. The nitrogen, already present in the atmosphere, remained.
There are no health hazards from breathing carbon dioxide in the atmosphere, but breathing pure carbon dioxide will kill you. The environmental hazard from carbon dioxide is that it is one of the greenhouse gases that is causing global warming.
Carbon dioxide
Carbon Dioxide dissolves in ocean water. Plants in the ocean use the carbon dioxide dissolved in the ocean water.
The concentration of Carbon Dioxide in arterial blood. Partial (Pa) Carbon Dioxide (CO2) pressure in ABG.
The air which we are breathing is containing about 20% ofcarbon dioxide which got into our bodies while breathing.
*This may be suspect to change Triton (Neptune's largest moon), Venus, Earth, and Mars.
The main bodies to have atmospheres that include carbon are, Venus, Earth, Mars, and Titan. Titan is a moon orbiting Saturn. The gas giants, Jupiter, Saturn, Uranus, and Neptune all have mainly hydrogen atmospheres.
Many organic chemicals when combusted in oxygen can create Carbon dioxide and water
Carbon is an element, but not carbon dioxide. Carbon dioxide is a compound of carbon and oxygen.
carbon-dioxide (carbon+oxygen) CO
Mars and Venus
There are two such planets, Mars and Venus. Venus has a much thicker atmosphere than Mars, but both atmospheres are about 95% carbon dioxide.
