Plastics can concentrate toxic pollutants, endangering marine ecosystems

Plastic debris is a serious environmental concern, as a physical pollutant as well as a chemical pollutant when it breaks down in the marine environment. A new study has now shown that plastics can also concentrate other pollutants, with significantly higher concentrations of toxic pollutants adhering to soft, rubbery plastics, rather than hard, glassy plastics.

Eco-design for flat screens should ensure quick dismantling for maximum resource recovery

Flat screen televisions and computer monitors should be designed so they can be quickly dismantled for recycling, a recent study says.

Good design could lower the costs of recycling and enable near-total recovery of precious metals from the waste screens.

Carbon dioxide successfully stored in volcanic rock — could help mitigate climate change

Storing atmospheric carbon dioxide (CO2) has the potential to mitigate the impacts of changes in climate. Researchers have now developed a way to inject CO2 into volcanic rock, and tested it in Iceland. Over 95% of the injected CO2 was mineralised (converted into a solid) within two years, instead of taking centuries or millennia as previously anticipated. The technique demonstrates potential for the permanent and safe storage of CO2 within basaltic rocks.

Dwarf galaxies are enigmas wrapped in riddles. Although they are the smallest galaxies, they represent some of the biggest mysteries about our universe. While many dwarf galaxies surround our own Milky Way, there seem to be far too few of them compared with standard cosmological models, which raises a lot of questions about the nature of dark matter and its role in galaxy formation.

Changes in European sulphur dioxide, nitrogen oxides and CO2 emissions since 1960

Emissions of sulphur dioxide (SO2) and nitrogen oxides (NOx) have fallen significantly across Europe since 1960. According to recent research, this is caused by a combination of factors including improved energy efficiency, a changing fuel mix and specific emission control measures. At the same time CO2 emissions have only increased moderately, mainly due to improvements in energy efficiency.

Considering the impact on soil carbon, biodiversity and ecotoxicity is important when assessing the environmental footprint of dairy products, suggests a new study, which explored the impacts of organic and conventional milk production in three types of system established in Western Europe. The study found that organic milk production had a significantly lower impact on ecotoxicity and biodiversity than conventional milk production, and suggests that including soil carbon changes in the assessment would result in greater reductions in the carbon footprint of organic, rather than conventional, milk — in some cases by up to 18%.
