The harmful effects of ozone that exist at low levels in the earth's atmosphere can be reduced when charging is done at night for electric vehicles, a new study has found. In the stratosphere, ozone becomes a protective layer of film that filters out ultraviolet rays that can cause skin cancer and DNA mutations in plants, reports AFP. However, ozone that is formed from the reaction between hydrocarbons and nitrogen oxide with sunlight can irritate the airways of people with cardiac or...

Black carbon (BC) and tropospheric ozone (O3) are harmful air pollutants that also contribute to climate change. The emission of both will continue to negatively impact both human health and climate. While our scientific understanding of how black carbon and tropospheric ozone affect climate and public health has significantly improved in recent years, the threat posed by these pollutants has catalysed a demand for knowledge and concrete action from governments, civil society, United Nations...

By Adam Voiland, NASA's Earth Science News Team An assessment report to be released this week by the United Nations Environment Program and the World Meteorological Organization shows that reducing emissions of two common air pollutants -- black carbon and gases integral to the production of ground-level ozone -- could slow the rate of climate change markedly over the next half-century. For decades, scientists have known both substances harm human health. More recently, evidence has emerged...

Current computer models may underestimate levels of ground-level ozone A team of scientists has, for the first time, completely characterized an important chemical reaction that is critical to the formation of ground-level ozone in urban areas. The team's results indicate that computer models may be underestimating ozone levels in urban areas during episodes of poor air quality (smoggy days) by as much as five to 10 percent. Ground level ozone poses significant health hazards to people,...
