Bromine also can remove ozone from the lowest layer of the atmosphere, the troposphere. Despite ozone’s beneficial role blocking harmful radiation in the stratosphere, ground-level ozone is a harmful pollutant. produced the study.

Controlling soot from fossil fuels and solid biofuels may be a faster method of reducing Arctic ice loss and global warming than other options, including controlling CH 4 or CO 2 , although all controls are needed, according to a new study by Dr. Mark Z. The study will be published this week in Journal of Geophysical Research (Atmospheres).

Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. An important analytical issue that needs to be addressed, the report notes, is the lack of lifecycle assessment studies focusing on a wider set of environmental impact indicators than greenhouse gas emissions.

succeeded in isolating the simplest CI and reported direct kinetic measurements of its reactions with water, NO, NO 2 , and SO 2. Dr. George Marston from the University of Reading (UK) notes that: The Criegee intermediates (CIs) are central to understanding the reactions of ozone with unsaturated compounds. Welz et al.

The data were gathered during the CalNex 2010 field study organized by ARB and the National Oceanic and Atmospheric Administration (NOAA). The researchers also found that every ship in California waters whose emissions were measured was using low-sulfur fuel.

Researchers at North Carolina State University are developing an ozone-based pre-treatment technique (ozonolysis) to release sugars from the energy grass miscanthus for production into renewable fuels or chemicals with minimal generation of chemical waste streams and degradation of the carbohydrate components.

2009), reproduced from Ramanathan and Feng (2008) Click to enlarge. HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. The Montreal Protocol has already delayed climate change by seven to 12 years, and put the ozone layer on the path to recovery later this century. Ramanathan.
