“Now they bring water back on the space shuttle and analyze it on the ground. The problem is there is a big delay. You’d like to be able to maintain iodine or silver [disinfectant] levels in real time...
Life Sciences | Read moreUMBRELLA against heavy metals
"Please take" - as simple as following a recipe in a cook book, soils containing heavy metals could be remediated in the future: Depending on the kind of contamination and the conditions on ...

"We found positive correlations between the levels of some metals in the waters of the Huelva estuary and those in the tissues of gilthead bream (Sparus aurata) and sole (Solea senegalensis)"...
Ecology, The Environment and Conservation | Read moreResearchers create freestanding nanoparticle films without fillers
In the last 25 years, ever since scientists figured out how to create nanoparticles ultrafine particles with diameters less than 100 nanometers they have come up with a number of different method...
Physics and Astronomy | Read moreResearch team rehabs contaminated sites using bioremediation
In Mogpog, Marinduque, a team of experts from UPLB headed by College of Arts and Sciences Dean and micro-biologist Dr. Asuncion K. Raymundo has been examining both the soil and bodies of water in the ...
Life Sciences | Read moreQuantum Dots May be Toxic to Cells, Environment Under Certain Conditions
Their study, the first to report on how different pH levels may affect the safety of QDs, appears in the Jan.15 issue of ACS’ Environmental Science & Technology, a semi-monthly journal. In the...
Ecology, The Environment and Conservation | Read moreNew method for tracing metal pollution back to its sources
Imperial College London researchers say their work is a major breakthrough as current methods for analysing zinc pollution only measure pollution in the atmosphere; they do not trace it back to its so...
Earth Sciences | Read moreHeavy metal link to mutations, low growth and fertility among crustaceans in Sydney Harbor tributary
The finding adds to mounting evidence that toxic sediments and seaweeds in Sydney Harbour are a deadly diet for many sea creatures.The new findings, published in the journal, Science of the To...
Ecology, The Environment and Conservation | Read moreUsing live fish, new tool a sentinel for environmental contamination
By measuring rates of oxygen use in developing fish, which are sensitive to contaminants and stressful conditions, the technology could reveal the presence of minute levels of toxic substances before ...
Ecology, The Environment and Conservation | Read moreLead and cadmium in raptors are a risk to their survival
Birds of prey that live in extensive geographical areas can accumulate high levels of heavy metals and metalloids in their bodies, as they are top of their food chain. Now researchers from the Univers...
Ecology, The Environment and Conservation | Read moreUNH Researchers Test Sediment-Scrubbing Technology In Cocheco River
Rather than dredging up the problem, or burying it under several feet of sand, they've created a patch � black geotextile mats designed to cap and stabilize pollution in place. Over the ne...
