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

Green Car Congress

In general, the researchers find that when air pollution is generated in one state, half of that pollution is lofted into the air and carried by winds across state boundaries, to affect the health quality of out-of-state residents and increase their risk of early death. and/or ozone. Early-death source–receptor matrices for 2011.

Researchers fully characterize reaction that affects ground-level ozone formation; a small but significant impact on predictive models

Green Car Congress

The two combine in the atmosphere to make either nitric acid or peroxynitrous acid; the so-called branching ratio of these two chemicals is important in models of ozone production. This means less of the hydroxyl radical and nitrogen dioxide go away, leading to proportionately more ozone, mostly in polluted areas, Okumura said.

Bromine also can remove ozone from the lowest layer of the atmosphere, the troposphere. Despite ozone’s beneficial role blocking harmful radiation in the stratosphere, ground-level ozone is a harmful pollutant. Bromine then reacts with a gaseous form of mercury, turning it into a pollutant that falls to Earth’s surface.

However, emissions do not just remain in conurbations; particles and gaseous pollutants can be transported thousands of kilometers by the wind. The transport and transformation of plumes from selected European and Asian major population centers (MPCs) will now be investigated with special focus on the rate of formation of ozone and aerosols.

In addition, other studies have shown that increases in PM 2.5 , NO 2 , and ozone were associated with lower test scores that were “equivalent to the effects of short-term reductions of thousands of dollars in district median household income.” The more vehicles that switch to running on electricity, the better.

DOE funds a fifth round of projects pairing manufacturing, high performance computing; KeraCel and solid-state batteries

Green Car Congress

Since it began, the HPC4Mfg Program has funded a total of 60 industry projects, ranging from improving the reliability and lifetime of wind turbines to studying how to mitigate defects in the 3D printing of metal parts to reducing emissions from semiconductor processing that could potentially harm the ozone layer.

Lifecycle study finds that environmental impacts of silicon-anode Li-ion battery could be roughly comparable with conventional Li-ion battery

Green Car Congress

The battery components (including anode, cathode, electrolyte, separator, cell casing, BMS, cooling system, and pack housing) together take a share of each corresponding impact ranging between 21% (HTP) and 77% (ETP).
