Pesticides responsible for bee poisoning: new screening technique proposed
A technique that can detect the array of pesticides bees might be exposed to has been developed in Poland. The simplicity, speed and small sample sizes required for screening makes this technique an improvement over other methods, say the researchers behind its development.

Acid mine drainage effectively remediated by natural wetlands
Natural wetlands can provide effective long-term remediation of contamination from abandoned mines, new research suggests. The study examined a natural wetland receiving water from a copper mine in the UK, and showed that the water's acidity and levels of toxic metals were significantly reduced once it had passed through the wetland.

Black carbon pollution from megacities and effects on global air quality
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.

Effective climate change mitigation in the form of seagrass restoration projects
Seagrass restoration projects could effectively mitigate climate change, capturing up to 1337 tons of CO2 per hectare after 50 years, new research suggests. If a carbon tax system was in place, the researchers add, these schemes would likely provide returns at least equal to the initial investment needed, assuming the tax was set at an appropriate level.

Underground wastewater disposal in the US linked to increase in earthquakes
The number of earthquakes of magnitude 3 or greater in the central and eastern US has increased significantly in recent years, from about 21 a year between 1967 and 2000, to over 300 between 2010 and 2012. Most of this increase seems to be linked to the deep injection of wastewater in underground wells, according to a recent review of seismic activity.

Green walls' economic sustainability assessed
Costs of installing, maintaining and disposing of some green wall systems may outweigh the value of some of their benefits for householders, a recent study suggests. While the researchers omitted some of the wider social benefits, they found that reductions in heating and air conditioning costs, longevity of green walls and increases in property values did not compensate for their costs. The researchers suggest that government incentives to lower the set-up costs could significantly increase the walls' economic sustainability.
