Study provides more insight into air pollution mechanisms that cause cardiovascular diseases

Green Car Congress

Air pollution, and fine dust in particular, is calculated to contribute to more than four million deaths each year. While the mechanisms by which air pollutants cause cardiovascular events is undergoing continual refinement, the preponderant evidence support rapid effects of a diversity of pollutants including all particulate pollutants (e.g.

NUS researcher links air pollution to increased residential electricity demand

Green Car Congress

Understanding what drives energy demand across the socioeconomic distribution of Singapore households can provide insight on the future energy demand of urban populations in the region’s cities as incomes rise. Besides electricity, the study found that households exposed to air pollution consumed more natural gas. —Prof Salvo.

OSU, Ford study provides insight into more efficient use of Rhodium in TWC applications

Green Car Congress

A study by a team from The Ohio State University and Ford is providing insight into the deactivation mechanism of rhodium in three-way catalysts (TWC) for automotive emissions control. This solution, however, is chemically inactive, meaning that it can’t scrub away harmful pollutants and gases, making the device effectively useless.

Study provides insight into mechanism of atmospheric new particle formation in polluted cities

Green Car Congress

de novo rather than as direct emissions—via nucleation and growth is a major source of aerosol pollution in terms of number concentration. In spite of a great deal of research, it is still a puzzle why and how such new particule formation (NPF) occurs in a highly polluted urban atmosphere.

Insight into benzene formation could help development of cleaner combustion engines

Green Car Congress

That insight could also help the car industry make cleaner combustion engines. The industrial processes behind crude oil refineries and the inner-workings of gas-powered combustion engines can emit PAHs, which can form into toxic air pollutants such as soot. Zhao et al.

Researchers suggests high level of air pollution in Northern Italy a co-factor in COVID-19 mortality rate

Green Car Congress

Researchers from the University of Siena in Italy and Aarhus University in Denmark are suggesting that the high level of pollution in Northern Italy should be considered an additional co-factor of the high level of COVID-19 fatalities recorded in that area.

New Emissions Analytics study suggests pollution from tire wear now 1,850 times worse than exhaust emissions

Green Car Congress

The aim is to bring transparency and insight to an area that has historically been under-researched, but which has now been thrown into the spotlight with ever-heavier vehicles and rapidly cleaning tailpipes. Emissions Analytics is looking to talk to anyone interested in research in this area.
