| 释义 | 一氧化碳 Carbon monoxide is a dangerous product of fire. Carbon monoxide is also one of the chemicals that create ozone pollution and urban smog. Install a CO detector to alert you of the presence of the deadly, odorless, colorless gas. Besides water, the plume also contained carbon monoxide, carbon dioxide, ammonia, sodium, mercury and silver. In high concentrations, carbon monoxide can harm human health by reducing oxygen to the heart and brain. Then, if the mix of waste is correct, the carbon and oxygen atoms involved recombine to form carbon monoxide and the hydrogen atoms link up into diatomic hydrogen molecules. And scientists say the plume contained things other than water, such as molecular hydrogen, carbon monoxide, mercury and silver. They both involve heating, rather than burning, waste until it breaks down into a flammable mixture of carbon monoxide and hydrogen, called syngas, and residual char, ash or slag. Additional pockets of high carbon monoxide concentrations southeast of Hudson Bay may have been transported to the area from the Northwest Territories, but they may also be from local fires. Moscow’s air is polluted at the best of times, but this smog, heavy with carbon monoxide, makes breathing difficult. That produces hydrogen and carbon monoxide, which can be converted to a liquid fuel. Values of tar, nicotine and CO where available as reported on packs were recorded for all products. One of the constituents of both smoke and urban pollution is carbon monoxide. Because they were so sensitive to deadly gases such as methane and carbon monoxide, a canary dropping off its perch was a highly visible signal to the miners that it was time to leave. The major air pollutants, such as carbon monoxide, carbon dioxide and particulate matter from vehicles have dropped by 20% in Beijing year-on- year, thanks to vehicle restrictions for the Olympics. We have one organism that lives off of carbon monoxide, and we use as a reducing power to split water to produce hydrogen and oxygen. Idling a car in a garage, even with the door open, is dangerous and exposes the driver to carbon monoxide and other noxious gases. In the process, they produce more smoke and more carbon monoxide than untreated objects do as they burn. This releases a mixture of hydrogen and carbon monoxide, known as syngas, and leaves a residue of amorphous elemental carbon called carbon black. The compounds, which include ammonia, carbon dioxide, carbon monoxide, sodium and, surprisingly, silver, could have come from the Earth, from the moon's interior, or from comets and asteroids. Finally, the map shows high carbon monoxide concentrations along the Atlantic Seaboard. The highest levels of carbon monoxide are shown in red, while lower levels are yellow and orange. |
