Levels of air pollution significantly increase on the island of Svalbard in the Norwegian Arctic when tourist cruise ships are present, according to a recent study. With shipping levels rising in the region, the researchers recommend that stricter emissions regulations are introduced in order to limit the impact of pollution on the Arctic environment.

Gas flaring and residential combustion are significant sources of soot, or black carbon, pollution in the Arctic, but their role has been underestimated until now, according to a recent study. The research indicates that flaring from oil and gas developments is the largest source of this pollutant, responsible for 42% of black carbon pollution in the Arctic.

Groups of chemicals used as flame retardants were present in the bodies of Antarctic rock cod (Trematomus bernacchii), young gentoo penguin (Pygoscelis papua), and brown skua seabird (Stercorarius antarcticus) collected from King George Island, Antarctica. This study is the first to find some of these chemicals in Antarctica, confirming that they undergo long-range transport and can reach isolated areas where they are not widely produced or used.

Dangerously high air pollution in the vicinity of shipbreaking yards has been detected by a recent study, where the concentrations of toxic chemicals in the air were found to be above carcinogenic risk limits (as set by the World Health Organisation). The research, carried out in Chittagong, Bangladesh, noted that shipbreaking activities and the subsequent processing and treatment of materials – particularly the burning of waste — result in emissions of persistent organic pollutants (POPs).

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.

Bioremediation is a technique that harnesses the power of nature to treat contaminated soils and groundwater. This study explored a technology that is effective at capturing groundwater pollutants and shows promise in extreme environments — the Permeable Reactive Barrier (PRB).

Researchers from NTU Singapore have developed a semi-autonomous robot that can disinfect large surfaces quickly. Named eXtreme Disinfection roBOT (XDBOT), it can be wirelessly controlled via a laptop or tablet, removing the need for cleaners to be in contact with surfaces, thereby reducing the risk of picking up the virus from potentially contaminated areas....

As ice melts, Antarctica's ground is rebounding at a surprising rate. Scientists think it's because the Earth's mantle is flowing faster there.
