Nanotechnology in the workplace

New technology, whether it is a novel cancer treatment or an innovative approach to farming, almost always comes with risk. Those risks are often first - and most severely - felt by industry workers, and nanotechnology is no different. Today, workers around the world are exposed to nanoparticles on a daily basis. There is much speculation, yet so far, little definitive information about how exposure affects workers. A report released by the International Council on Nanotechnology in November 2006 ("A Survey of Current Practices in the Nanotechnology Workplace" - pdf download, 2.2 MB), offers a clear picture of the situation. "The properties for which novel nanoscale materials are designed may generate new risks to workers, consumers, the public, and the environment. While some of these risks can be anticipated from experiences with other synthetic chemicals and with existing knowledge of ambient and manufactured fine particles, novel risks associated with new properties cannot easily be anticipated based on existing data." Questions, such as how to measure toxicity and how to monitor and control exposure, remain unanswered.
