2. Carbon dioxide is 1.5 times heavier than air and will not readily disperse in the atmosphere. Asphyxiation may be a hazard in confined areas. 二氧化碳比空气重1.5倍,在空气中不易扩散。窒息是在狭窄区域的危险。 3. Carbon dioxide in high concentrations is toxic to humans. See the toxicity ...
This high-resolution carbon dioxide (CO2) map uses a new model from the Goddard Earth Observing System (GEOS) to map CO2 dispersion in unprecedented detail.

The major source ofCO emission in the atmosphere is the gasoline-poweredinternal combustion engine. Special industrial processeswhich contribute significantly to CO emission are ironfoundries, particularly the cupola; fluid catalytic crackers;fluid coking; and moving-bed catalytic crackers in thermal...
An ultra-high-resolutionNASAcomputer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe. Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources. Credit: NASA’s Goddard Spa...

Diffuse CO2 emissions through the soil or via carbonated springs in volcanic areas do not appear to represent a threat as long as the CO2 is able to disperse into the atmosphere. However, when CO2 is able to build up in enclosed spaces it poses a definite threat. Large CO2 clouds ...

Forest restoration is fundamental to overcoming biodiversity crises and climate change. In tropical forests, animals can improve forest recovery as they disperse >70% of tree species. However, representing animals in restoration and climate change pol
Both the receptor and the transducer components of a sensor can be fabricated using carbon nanotubes [2]. Kong et al. [3] in year 2000 observed changes in the conductance of single walled carbon nanotube field effect transistors (SWCNT-FET) when exposed to nitrogen dioxide (NO2) and ammonia...
