Several pollutants that are not covered by UN regulations could be harmful to humans, according to new research in the Balkans. By sampling air at various urban sites, the research showed that polycyclic aromatic compounds (PAHs) have the potential to be a major health risk.

A new tool used to investigate exhaust emissions of marine vessels has been developed and applied to shipping in the Baltic Sea.

New research has estimated the global footprint of emissions from commercial aircraft. In 2006 nearly 190 million tonnes of fuel were burnt and 162 million tonnes of carbon from CO2 were emitted. The vast majority of the fuel was burned in the Northern hemisphere and half the emissions were over the US, Europe and East Asia.

Global air quality will significantly deteriorate by 2050 unless further steps are taken to cut current emissions from human activities, according to recent research. Most people around the world will be affected by worsening air quality with hotspots of particularly poor air occurring in China, northern India and the Middle East.

Air pollution from the world’s megacities not only has local impacts, but can spread to remote regions of the world. Recent research has highlighted, for example, that megacities are a source of black carbon pollution in lowest kilometre of atmosphere in the Arctic, with European megacities contributing more than others.

Reductions in emissions of fine particle air pollution can prevent premature deaths, not just locally, but also in countries thousands of kilometres away, new research illustrates. The transcontinental study examines the effects of reducing air pollution emitted from Europe, North America, South and East Asia by 20% and shows that, for example, reductions in the EU would mean 3700 fewer premature deaths in the other three regions every year.

Greater amounts of air pollutants emitted in East Asia will move around the globe under climate change, a recent study predicts. Changes to wind speeds and air pressure will mean that movement of pollution from this region is enhanced under a changing climate. These results highlight the need for globally coordinated efforts to tackle air pollution and climate change.

PM_2.5 air pollution can have a significant impact on human health, not only for local populations, but also in regions far from its source of emission, shows a new study. The study calculates ‘damage factors’ to human health of PM_2.5 and in different parts of the world.

Globally, more than 3.2 million premature deaths per year are attributed to exposure to ambient fine particulate matter (PM2.5). A new study estimates that 2.1 million premature deaths could be avoided if countries achieved the WHO guideline for PM2.5. Even meeting their closest WHO interim concentration targets could avoid 750 000 (23%) deaths attributed to PM2.5 per year.

Polycyclic aromatic hydrocarbons (PAHs) enter the environment in large quantities via the combustion of fossil fuels and organic matter. They are a cause for concern given their known toxicity, potential to cause cancer and ability to move large distances in the atmosphere — meaning that they are found in remote or protected areas, such as the Arctic, even if not emitted there. This study explores how PAH levels in the Arctic atmosphere have changed over the past 20 years at three sites in Canada, Norway and Finland. The results show that, despite a global decrease in PAH emissions in the same timeframe, the air concentrations in the Arctic are not significantly declining — possibly partly as a result of local warming causing more volatile PAHs to move from the surface to the air.
