  • Bringing life back to dead zones

    Dead zones — those regions that can be found in the Great Lakes, Chesapeake Bay, and even the Gulf of Mexico — are a serious problem for U.S. waterways. These hypoxic zones, the result of excess nitrogen and phosphorus run off, can lead to algae blooms that can stifle aquatic life. Regulators are doing their part to reduce these dead zones by mandating the decrease of nutrient runoff ...

  • Silver nanoparticles could pose risk to aquatic ecosystems

    Silver nanoparticles are toxic to common bacteria at concentrations found in many aquatic environments across the globe, new research has found. Bacteria often form a key part of ecosystems and these impacts may be felt by the entire system, the researchers warn. Silver nanoparticles are between one and a hundred nanometres (nm) in size and are now used for their antimicrobial action in a wide ...
