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. Electric power generation is the greatest contributor to out-of-state pollution-related deaths, the findings suggest.

MIT researchers build model simulating atmospheric transport of PAHs; how chemicals get to the Arctic

Green Car Congress

MIT researchers have built a model to simulate long-range atmospheric transport of polycyclic aromatic hydrocarbons (PAHs). The model that will be further developed as part of an NSF-funded project to track how chemicals get to remote Arctic environments. Persistent organic pollutants are chemicals of substantial international concern.

Cambridge-MIT Study Attributes ~8,000 Premature Deaths Per Year to Aircraft Cruise Emissions

Green Car Congress

A study by a team from the University of Cambridge (UK) and MIT attributes ~8,000 premature mortalities per year to aircraft cruise emissions. However, recent regional modeling work indicates that cruise emissions may contribute a significant fraction of aircraft-accountable ground-level pollutant concentrations on a regional scale.

Study: marine cyanobacteria produce 100s of millions of tonnes of hydrocarbons annually

Green Car Congress

An international team of researchers, led by the University of Cambridge, has estimated that photosynthetic marine cyanobacteria annually produce hundreds of millions of tonnes of hydrocarbons in the oceans. Oil spills cause widespread damage, but some parts of the marine environment recover faster than others. —Lea-Smith et al.
