The World’s Lakes are Rapidly Losing Oxygen Image Credit: Shutterstock.com / Yevhenii Chulovskyi A new study examines surveys of lakes conducted over the past eighty years finding freshwater bodies are losing dissolved oxygen more quickly than the oceans. Earth’s temperate freshwater lakes are losing oxygen much more quickly than its oceans, new research has revealed. The trend is being driven predominantly by climate change and threatens not only our supply of clean drinking water but also the biodiversity of some of the planet’s most beautiful ecosystems. In fact, though freshwater l...

US Patent Granted to Graphene-Based Environmental Remediation Technology Image Credit: Shutterstock.com / Rost9 A graphene-based material that could filter heavy metals and other contaminants from water and air has been patented in the US.  Environmental remediation involves the removal of pollutants or contaminants from areas of the environment such as solid, groundwater, sediment and surface water. There is a wide range of approaches, techniques and methods that can be used to clean up harmful pollutants such as heavy metals like mercury and arsenic. Among these different approaches to cl...

Co-authors Vinayak Dravid and Stephanie Ribet examine their phosphate elimination and recovery substrate. Credit: Northwestern University New research suggests that a membrane-embedded with specific nanostructures could provide a ‘plug & play’ solution to removing pollutants from aquatic ecosystems.  While concentrations of phosphates in rivers, lakes and other bodies of water continue to soar, reaching dangerous levels, the global farming industry is having the opposite problem. Reserves of phosphate fertilizers  —  the key to farming that forms at least half of the world’s food...

The UK is moving forward with trials of mechanisms to draw carbon dioxide from the air as part of a drive to meet 2050’s net-zero emission target. Image Credit: shutterstock.com/Dave Head As part of a global scheme to mitigate the effects of climate change, a number of governments have pledged to reach net-zero carbon emissions by 2050. Whilst the goal is admirable, and the investment in clean energy that it requires is a positive step in the energy sector, scientists are still predicting that this action will not be enough to slow the quickening progress of global warming. This is coupled...
