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.

Chalmers study finds ship exhaust gas scrubbers responsible for up to 9% of certain hazardous emissions into Baltic Sea

Green Car Congress

The Baltic Sea is one of the most polluted sea areas in the world due to the northerly geographic location, natural hydrographic properties, large catchment area and the semi-enclosed character of the brackish inland sea. Also, the cancer-causing PAHs are difficult to degrade and can spread widely in the environment before breaking down.

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, D.
