Thebacteria in the soil take the nitrogen from the fertilizer andmake more nitrous oxide with it.So how can we help? "Number one is to not wastefood, " Wagner Riddle, a scientist from Canada, said.4. That number comes from a U. S. universitystudy. "There is a lot that goes into ...
Less is known about nitrous oxide use in the general population, but this also appears to be increasing over time. The Australian Institute of Health and Welfare (AIHW) reported in their National Drug Strategy Household Survey that past year use of inhalants, which included nitrous oxide, increas...
Note: on the second stage of analgesia, oxygen knobs can be adjusted to about 45% (that is, nitrous oxide is 55%), increase the amount of analgesia. 翻译结果4复制译文编辑译文朗读译文返回顶部 正在翻译,请等待... 翻译结果5复制译文编辑译文朗读译文返回顶部 ...
“In Europe and North America, we have succeeded in decreasing growth in nitrous oxide emissions, an important contributor to climate change and stratospheric ozone depletion,” he added. “Unfortunately, the same can’t be said for Asia and South America, where fertilizer use, intensification...
Nitrous oxide from agriculture and other sources is accumulating in the atmosphere so quickly it puts Earth on track for a dangerous 3℃ warming this century,our new researchhas found. Each year,more than 100 million tonnes of nitrogenare spread on crops in the form of synt...
For instance, the water that is used to cool polyamides often introduces pollutants into the ecosystems surrounding manufacturing plants, and the production of adipic acid, which is used to create most forms of nylon, releases nitrous oxide into the environment. Nitrous oxide is 300 times worse ...
They are used to power farm machinery, to take food to market (and home), to store food waiting for processing and to cook food. The researchers also calculated methane. Mostly cows release this gas. Scientists also calculated the nitrous oxide(一氧化二氮)released during the plowing and ...
The use of nitrous oxide, or laughing gas during childbirth fell out of favor in the United States decades ago, and just two hospitals—one in San Francisco and one in Seattle—still offer it. But interest in returning the dentist office staple to the delivery room is growing: respected hos...
