Water pollution by toxic elements is a major economic and environmental concern, and mercury is one of the most poisonous of the elements to be released into the environment by industry. Mercury exposure can cause severe ill health. Efficient, simple and convenient methods to remove mercury from industrial and other waste streams and drinking water are essential. This study successfully trialled a new technique, using magnetised multi-walled carbon nanotubes (MWCNTs), to remove mercury from waste water.

Planting trees in urban areas has been recognised as a cost-effective means of reducing air pollution for several major cities worldwide. In a new study, the impact of tree species diversity on levels of ozone pollution in Rome was assessed. The results suggest that different species of tree complement each other in providing this important ecosystem service.

Nitrous oxide (N₂O) is a potent greenhouse gas and atmospheric pollutant. A new study proposes tackling both problems by removing N₂O from the atmosphere using a combination of two innovative technologies — photocatalytic breakdown of the N₂O to nitrogen and oxygen, and this within a solar chimney power plant that generates renewable electricity. Although some way off from commercial development, the researchers say this approach is feasible, and they outline how these two technologies can be integrated to reduce the climate impact and polluting effects of N₂O emissions.
