New system to detect mercury in water systems

A new ultra-sensitive, low-cost and portable system for detecting mercury in environmental water has been developed by researchers. "The promising sensing performance of this system along with its cost-competiveness and portability make it an excellent potential alternative to current analytical techniques," says the project's leader. "This technique could provide the basis for future point-of-analysis systems for monitoring water quality on site and may help implement better monitoring processes around the world."
