Adam Noble and Shayla Larson, entering grade twelve at Lakefield District Secondary School in Ontario, represented Canada in the 2011 Stockholm Junior Water Prize competition this week in Stockholm Sweden. The pair was selected by the Canadian Water Environment Federation Member Associations from three projects chosen at the Canada-Wide Science Fair in May, where their project won a senior gold medal, the senior Environment Challenge, a Manning Young Canadian Innovation Award, and entrance scholarships to 5 Canadian universities.
Their project, The Hazards of Nanosilver Uncovered, examined the effect of nanosilver, an increasingly common commercial and industrial antimicrobial agent, on Euglena, a photosynthetic protozoan. Results of their study indicated that absorbed nanosilver is toxic to Euglena, resulting in structural and functional changes and cell death.
This year's winner of the Stockholm Junior Water Prize was Alison Bick of the USA who won the coveted honour with a project that combined micro-fluidic devices, cell-phones, and chemical indicators to evaluate water quality. Her innovative method not only accurately assesses the bacterial content of water, it is both significantly faster and up to 200 times less expensive than standard testing procedures.
The jury also awarded a Diploma of Excellence to Prasan Warnakula from Sri Lanka for his project "From pollutant to pulp: industrial symbiosis of textile finishing, paper recycling and pulp production."
The announcements came tonight during an award ceremony at the 2011 World Water Week in Stockholm, where high-school age students from 28 countries gathered after winning their national competitions, providing them with the opportunity to compete for the international prize. The international winner receives a US $5,000 award and a crystal sculpture presented by H.R.H. Crown Princess Victoria of Sweden, Patron of the Stockholm Junior Water Prize.The Stockholm International Water Institute administers the competition, which is sponsored globally by ITT Corporation.
