On November 27-29 of 2007, the 314th session of the Xiangshan Science Conference was held on nanotechnology and environmental safety.

In recent years, the study on the bio-safety of nanotechnology has been gradually developing in China. However, the domestic understanding of its importance is insufficient, not to mention the establishment of environmental safety standards of nanotechnology, and an evaluation system.

The experts believed that the research on environmental safety and nanotechnology involved multiple disciplines as diverse as nanotechnology, chemistry, physics, environment and ecology and such research would promote the healthy development of nanotechnology.
