County health officials said today they don`t believe there will be any long-term effects from the methane gas leak in the Porter Ranch neighborhood of Los Angeles.SCOTT PELLEY, MIREYA VILLARREAL
a strong greenhouse gas (1) methane is a colorless, odorless gas; it is also a potent greenhouse gas, and once released into the atmosphere, it absorbs heat radiating from earth's surface. that's why methane is a major contributor to the planet's increasing temperature rise .-- or ...

Methane's concentration in the troposphere, after a long period of stabiliszation, is rising again since 2006. Here I will give a review on methane, its atmospheric chemistry, its emission sources and global budget. 展开 关键词:methane budgets climate change greenhouse gas pollutant ...
Gas chroma- tography analysis showed that the strain could use methane as the sole carbon and energy source. Based on 16S rDNA sequence analysis, the strain was identified as Pseudomonas aeruginosa. Effects of inoculum size, temperature, methane content and initial pH of media on cell growth ...
Cows produce much methane (甲烷) the world’s second worst greenhouse gas, as they break down the grass. They are a large source of the greenhouse gases that are driving climate change. Now scientists have shown the pollution from cows can be reduced by adding a little seaweed (海藻) to ...
