Proficiency test of non-target screening with gas chromatography mass spectrometry to confirm a detected contamination of raw and drinking water

Much of the water supply industry has implemented online monitoring and warning systems for chemical or biological contaminations. When a contamination is detected, further investigations are necessary to confirm or to cancel the initial alarm. The proficiency of a non-target screening approach with solid phase extraction and GCMS in full-scan mode was examined. A selection of pesticides and ...

Testing of Oil Recovery Skimmers in Ice at Ohmsett - The National Oil Spill Response Research & Renewable Energy Test Facility

Abstract The mechanical recovery of oil in ice-infested water presents unique and difficult clean-up challenges. Ice can impede the movement of spilled oil making it less available for removal by the active components of oil recovery skimmers. Ice and slush that is recovered with oil can jam the skimmer, pump inlets and hoses and can provide an environment for enhanced emulsion formation. ...

Validation of a new standardized test method for the freshwater amphipod Hyalella azteca: Determining the chronic effects of silver in sediment

Environment Canada has developed a new 42 day sediment toxicity test method that includes a reproduction test endpoint with the freshwater amphipod Hyalella azteca. Due to concerns that existing standard methodologies, where adults are transferred to a water‐only exposure before release of their first brood at day 28, will lead to internal contaminant depuration and loss of sensitivity, the EC ...

Smart Grid: The game

In his best seller “Outliers,” Malcolm Gladwell shows that it is not equipment failure or storms that typically cause planes to crash, but wrong decision-making. Much the same can be said for the power grid crash that took down a large swath of the Northeast in August 2003. The emerging smart grid is supposed to make our power system more reliable. The bad news is that it also will add complexity ...
