Study links ambient PM2.5 and ozone specifically caused by vehicle exhaust emissions to ~361,000 premature deaths worldwide in 2010 and ~385,000 in 2015

A new study provides the most detailed picture available to date of the global, regional, and local health impacts attributable to emissions from four transportation subsectors: on-road diesel vehicles; other on-road vehicles; shipping; and non-road mobile engines such as agricultural and construction equipment.

Study: consumer products overtake transportation as largest source of VOCs air pollution in cities

Green Car Congress

Consumer products such as shampoo, cleaning products and paint now contribute as much to emitted volatile organic compounds (VOCs) in cities as tailpipe emissions from vehicles, according to a new study led by NOAA. Even so, lotions, paints and other products contribute about as much to air pollution as does the transportation sector.

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

Green Car Congress

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.

CU Boulder study: routine household activities generate air quality on par with major polluted city

Green Car Congress

Cooking, cleaning and other routine household activities generate significant levels of volatile and particulate chemicals inside the average home, leading to indoor air quality levels on par with a polluted major city, according to a study by researchers at the University of Colorado Boulder.

Perhaps surprisingly, this reduction in cross-state pollution also appears to be related to electric power generation: In recent years, regulations such as the Environmental Protection Agency’s Clean Air Act and other changes have helped to significantly curb emissions from this sector across the country. and/or ozone. and/or ozone.

Researchers report on potential long-range atmospheric emissions impacts of increased ethanol fuel use in North America

Green Car Congress

Acetaldehyde is classified as a hazardous air pollutants (HAP) regulated under Title III of the Clean Air Act Amendments. Here we use a global 3D chemical transport model (GEOS-Chem CTM) applied to an ensemble of airborne observations to derive new constraints on natural and anthropogenic ethanol sources in North America.
