Common nanoparticles found to be highly toxic to Arctic ecosystem
Date:4/6/2011

ogen themselves and nitrogen fixation is essential for plant nutrition, the presence of these particular microbes in soil is vital for plant growth. The analysis of the soil sample six months after the addition of the silver nanoparticles showed negligible quantities of the important nitrogen-fixing species remaining and laboratory experiments showed that they were more than a million times susceptible to silver nanoparticles than other species.

These pioneering findings by Queen's researchers Niraj Kumar and Virginia Walker and Dowling College's Vishal Shah have been published today in the Journal of Hazardous Materials, the highest ranking journal in Civil Engineering.
