ICL, CMU study associates PM2.5 air pollution in US with >30,000 deaths and reduced life expectancy

Green Car Congress

The tiny particles, around 30 times smaller than the width of a human hair, can be inhaled deep into the lungs, and have been associated with increased risk of a range of conditions including heart attack and various forms of lung disease. The amount of this fine particle pollution in the US has declined since 1999. µg/m 3 and 13.2

WUSTL study finds use of air conditioning reduces in-car pollution

Green Car Congress

Traffic is a major source of harmful pollutants; daily peak exposures tend to occur near roadways or while traveling—or being stuck—on them. That gave them rare, real-world look at pollutant exposure. With windows closed, the pollutants took longer to enter the vehicle cabin, but also longer to exit it.

California ARB study finds commuters’ exposures to air pollution greatly depends on mode of travel; light rail, personal vehicles the lowest

Green Car Congress

The mode of travel you take on your daily work commute can make a big difference in your exposure to air pollution, according to a new study by researchers at the California Air Resources Board (ARB). Boxplot of average PM 2.5 , BC, UFP, and LDSA [lung deposited surface area] concentrations for each commute mode. Click to enlarge.

Study: traffic density, wind and air stratification influence concentrations of NO2

Green Car Congress

In connection with the effects of the COVID-19 pandemic, satellite measurements made headlines showing how much the air pollutant nitrogen dioxide (NO 2 ) had decreased in China and northern Italy. In 2018/2019, for example, various measures were taken in Germany, ranging from a reduction in the number of lanes (e.g. in Stuttgart).
