Study suggests air pollution may be linked to heightened mouth cancer risk; PM2.5 and ozone

Green Car Congress

High levels of air pollutants, especially fine particulate matter (PM 2.5 ) and to a lesser extent, ozone, may be linked to a heightened risk of developing mouth cancer, suggests a study by a team of Taiwanese researchers. Diagnoses of mouth cancer were then linked to local area readings for air pollutants taken in 2009.

Study finds São Paulo switch from ethanol to gasoline dropped local ozone levels by 20%, increased CO and nitric oxide concentrations

Green Car Congress

A study by a pair of researchers at Northwestern University found that when fuel prices drove residents of São Paulo, Brazil, to switch from ethanol to gasoline in their flexible-fuel vehicles, local ozone levels dropped 20%. At the same time, nitric oxide and carbon monoxide concentrations tended to go up. 3 , respectively, being 2.7

These State Implementation Plans (SIPs) are the roadmaps to meeting the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS) of 0.08 In 1997, EPA first established the 8-hour ozone standard, which replaced the older 1-hour ozone standard (0.12 Source: EPA.

International study identifies 14 key measures to reduce methane and black carbon emissions; reduction in projected global mean warming of ~0.5 °C by 2050

Green Car Congress

A study by an international team of researchers, led by Drew Shindell of NASA’s Goddard Institute for Space Studies (GISS) in New York City, has identified 14 measures targeting methane and black carbon (BC) emissions that could reduce projected global mean warming ~0.5°C °F) by 2050, as well as improving human health and agriculture.

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

Green Car Congress

The researchers analyzed extensive satellite and ground-based measurements of nitrogen oxides and carbon monoxide. They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency.

Urban CO2 Domes May Enhance May Increase Ozone and PM, With Accompanying Increase in Mortality

Green Car Congress

While the existence of higher CO 2 levels overs cities—CO 2 domes—has been known for more than a decade, their effects on local air pollution has up to now not been explored. As such, reducing locally emitted CO 2 may reduce local air pollution mortality even if CO 2 in adjacent regions is not controlled. Jacobson, 2010. Mark Jacobson.

Pollution plumes in Paris air are richer in gaseous aromatic compounds than in LA; gasoline engines main source of VOCs

Green Car Congress

The study also shows that the proportion of gaseous aromatic compounds—apart from benzene—in hydrocarbon emissions is two to three times greater in pollution plumes in Paris than in Los Angeles, even though the total quantity of hydrocarbons emitted in Los Angeles remains considerably greater than in Paris.
