The Nanohazard Symbol Contest was initiated by the action group on Erosion, Technology, and Concentration (the ETC Group), a global science and technology governance nongovernmental organization (NGO). The symbol is meant to increase the visibility of a nanoscale science and technology safety discourse. The winning symbols of the 2007 Nanohazard Symbol Contest were Dimitris Deligiannis (Greece), Shirley Gibson (Scotland), and Kypros Kyprianou (England).

Sixteen 2007 contest winners were chosen from the 482 designs submitted by people from 24 countries.

None

The ETC Group was one of the first NGOs, if not the first, to question medical and environmental health safety issues with existing nanoscale materials, as well those in development and envisioned. The ETC Group initiated the Nanohazard Symbol Contest, feeling that a common, internationally recognized symbol warning of the presence of engineered nanomaterials was overdue. The ETC Group also used the term nanohazard to highlight social hazards, such as what would happen to the livelihood of people, particularly in low-income countries, if nano products replaced natural products. The ETC Group has called for a moratorium on nanoparticle production and release to allow for a full societal debate and the development of regulations and nanogovernance structures to protect workers, consumers, and the environment, and to minimize possible negative consequences.

Details of the Competition

The ETC Group and other involved parties sent out notice of the competition through their global networks, which included artists, designers, scientists, students, regulators, and members of the public. Entries were judged on their conceptual as well as artistic merit. All submitted entries were treated as copyright-free, and entries submitted with copyright conditions (other than creative commons) were not considered. An independent panel of judges selected by the ETC Group selected 16 finalists. The second stage was the public judging which took place at the World Social Forum in Nairobi, Kenya, in January 2007. Winners of Nanohazard Symbol Contest were announced at the World Social Forum. The competition drew 482 entries from 24 countries. The winning designs were submitted to international standard-setting bodies responsible for hazard characterization.

Response to the Symbols

Members of the NGO community who were already involved in the nano safety discourse saw the competition as a positive, whereas groups that questioned the safety discourse did not. Some felt that the symbols were not representative of the social hazards attached to current and future nanoproducts and processes, and felt that the symbols only highlighted medical and environmental health and safety issues. Others felt that the symbol did not reflect the dangers attached to other nanoscience areas, such as nanostructures or molecular manufacturing.
