(Japan) report in the journal Angewandte Chemie the development of a mesoporous two-line ferrihydrite (2LFh)—ferrihydrite is a widespread mineral composed of iron, oxygen, and water—that could lead to a new generation of ozone filters in electrostatic devices and aircraft applications. removal; it showed about 95 % O 3.

In its recently released Inventory of US Greenhouse Gas Emissions and Sinks: 1990 – 2011 ( earlier post ), the US Environmental Protection Agency (EPA) reported that methane (CH 4 ) emissions from the field production of natural gas have declined by 36% from 2007 to 2011 (from 83.1 a global warming potential of 21.

Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. Hydrogen is not a greenhouse gas, but its chemical reactions in the atmosphere affect greenhouse gases such as methane, ozone, and stratospheric water vapor. Sand et al.

The two vehicles, working together to gather upwind and downwind readings of sources, will monitor for methane, nitrous oxide, carbon dioxide, halocarbons, sulfur hexafluoride, carbon monoxide, ozone and particulate elemental carbon; as well as particulate matter size and distribution. While California’s population is less than 0.5%

NO x is a precursor for both ground level ozone and secondary PM 2.5 It is important to state that there are several technology paths to achieve these levels of emissions, and some of them can simultaneously lower greenhouse gas emissions, such that the NO x reductions do not compete with the CO 2 reductions.

Although the catalyst is in use, exactly how it converts NO x to nitrogen and water with the help of ammonia (urea) hasn’t been entirely clear. In addition, they produce as a byproduct the greenhouse gas nitrous oxide (known to dental patients everywhere as laughing gas). Lei Ma, Yisun Cheng, Giovanni Cavataio, Robert W.

That ranks the effects of soot ahead of methane, an important greenhouse gas. Particle traps filter out soot particles from exhaust fumes. Warming of the air by any chemical, including soot, enhances natural surface emissions of water vapor [e.g., These three gases are all greenhouse gases, and ozone is a surface air pollutant.
