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

Green Car Congress

More than half of all air-quality-related early deaths in the United States are a result of emissions originating outside of the state in which those deaths occur, MIT researchers report in a paper in the journal Nature. Now it’s looking like other emissions sectors are becoming important. That wasn’t really possible before.

However, emissions do not just remain in conurbations; particles and gaseous pollutants can be transported thousands of kilometers by the wind. A total of approximately 100 flight hours are planned for the measurement flights in the emission plumes of Asian cities, said John P. HALO in-hangar in Taiwan.

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.

Why Schools Should Electrify Their Bus Fleets

Numerous studies compiled by the Environmental Defense Fund show that in addition to harming the community, diesel school buses also “self-pollute” with emissions entering the bus cabin, to the point that “ the interior cabin of a diesel bus is five times higher ” than outside the bus.

National Academies Report Examines Hidden Cost of Energy Production and Use in US; Estimates $120B in 2005

The committee that wrote the report focused on monetizing the damage of major air pollutants—sulfur dioxide, nitrogen oxides, ozone, and particulate matter—on human health, grain crops and timber yields, buildings, and recreation. Most vehicle and fuel combinations had similar levels of greenhouse gas emissions in 2005.

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 researchers characterized nanowastes and nanoparticle emissions from the SiNW synthesis. 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).
