10-year study shows how air pollution fosters heart disease; accelerated plaque build-up in arteries

Green Car Congress

Long-term exposure to particulate air pollution has been linked to an increased risk of heart disease, but the biological process has not been understood. Participant-specific pollutant concentrations averaged over the years 2000–10 ranged from 9.2–22.6 The study is published in The Lancet. and NO x between 1999 and 2012. μg PM 2.5 /m

Crowdsourcing air pollution measurements: iSPEX-EU 2015

Green Car Congress

A collaboration led by researchers at Leiden University in The Netherlands has launched a Europe-wide citizen campaign— iSPEX-EU 2015 —to use a smartphone add-on and app to measure atmospheric aerosols (tiny particles), resulting in a broad-based data set with high spatio-temporal resolution. iSPEX add-on.

New exhaust catalyst features thermal durability and high reactivity at low operating temperatures

Green Car Congress

Catalytic converters have been used in the US since the 1970s as a way to clean up pollutants from vehicle exhaust. In the catalytic process, rare metals such as platinum, are used in a chemical reaction to convert carbon monoxide and other pollutants to non-toxic carbon dioxide, nitrogen, and water. —Yong Wang.

New study shows that inhaled nanoparticles can travel into the blood and accumulate

Green Car Congress

A study by researchers from the University of Edinburgh and the National Institute for Public Health and the Environment in the Netherlands has found that nanoparticles, such as those found in air pollution, can travel into the blood and accumulate in diseased blood vessels.

EU research project IDEALFUEL seeks to develop marine low-sulfur heavy fuel oils from biomass; Bio-HFO

Green Car Congress

The use of heavy fuel oils (HFOs) contributes to global warming due to the fossil origin of these fuels and, moreover, generating non-negligible emissions of pollutants such as sulfur oxides. IDEALFUEL is coordinated by Eindhoven University of Technology and involves participants from four countries. The participants are Vertoro B.V.

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. Determining effective strategies for mitigating surface ozone (O 3 ) pollution requires knowledge of the relative ambient concentrations of its precursors, NO x , and VOCs.
