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

Furthermore, airborne chemicals that originate inside a house don’t stay there: Volatile organic compounds (VOCs) from products such as shampoo, perfume and cleaning solutions eventually escape outside and contribute to ozone and fine particle formation, making up an even greater source of global atmospheric air pollution than cars and trucks do.

HEI launches two new non-tailpipe particulate emission studies

Green Car Congress

Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles. HEI receives balanced funding from government and industry.

Eaton introduces set of products to reduce vapor emissions during refueling; LEV III regulations

Green Car Congress

This category of emissions is the largest source of volatile organic compounds (VOCs) produced by automobiles, which are a main source of haze, ozone, and particulate matter. If fuel vapor is released into the atmosphere, it contributes to a category of pollutants known as evaporative emissions.

James Donaldson, is a mixture of thousands of chemical compounds spewed into the air by automobiles, factories and a host of other sources. When in the air, these compounds may combine with volatile organic compounds to produce ozone, the main component of smog. Among these compounds are nitrogen oxides. —James Donaldson.
