Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

Study finds significant slowdown in decrease of NOx emissions in US; implications for air quality management

Green Car Congress

NO x emissions have not been decreasing as expected in recent years (2011–2015) when comparing top-down estimates from satellites and surface NO 2 measurements to the trends predicted from the US Environmental Protection Agency’s emission inventory data, according to a new study by an international team of researchers.

Additionally, the study found that the population-weighted mean concentrations of ozone increased globally by 8.9% An additional 217,000 deaths were attributable to long-term ozone exposure. and ozone (O 3 ).

Study estimates ~4M children worldwide develop asthma each year because of NO2 air pollution

Green Car Congress

The study, based on data from 2010 to 2015, estimates that 64% of these new cases of asthma occur in urban areas. NO 2 is a pollutant formed mainly from fossil fuel combustion, and traffic emissions can contribute up to 80% of ambient NO 2 in cities. —Susan Anenberg.

HEI ACES study of lifetime animal exposure to New Technology Diesel Engine exhaust finds no lung cancer

Green Car Congress

exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. The study exposed laboratory rats 80 hours a week, for up to 30 months, to emissions from a heavy-duty diesel engine meeting 2007 US EPA standards using new filters and other control technology.
