MIT study: half of US deaths related to air pollution are linked to out-of-state emissions

Green Car Congress

The study focuses on the period between 2005 and 2018 and tracks combustion emissions of various polluting compounds from various sectors, looking at every state in the contiguous United States, from season to season and year to year. Scientists have long known that pollution observes no boundaries, one of the prime examples being acid rain.

EPA’s 2011 Toxics Release Inventory shows air pollutants continue to decline, releases of toxic chemicals up

Green Car Congress

Total toxic air releases in 2011 declined 8% from 2010, mostly because of decreases in hazardous air pollutant (HAP) emissions, even while total releases of toxic chemicals increased for the second year in a row, according to the US Environmental Protection Agency (EPA) annual Toxics Release Inventory (TRI) report published today.

LSBU researchers investigating metal hydride hydrogen storage for buses

Green Car Congress

Researchers from London South Bank University (LSBU), School of the Built Environment and Architecture, are investigating the use of metal hydrides to absorb, release and store hydrogen for fuel cell buses. From Adelhelm & Jongh (2011). Hydrogen is stored by reaction with a metal to form a hydride (exothermic reaction). EP/T022760/1.

USC researchers find car ventilation setting critical to in-cabin exposure to particulate pollutants; new model for aiding exposure assessments

Green Car Congress

In-vehicle-to-outside (I/O) ratios for four pollutants under different ventilation settings. Researchers at USC have found that using recirculation rather than outside air ventilation in a car can effectively reduce in-cabin exposure to on-road particle pollution.
