DR. Tom Beer, CSIRO: "I see these being used in any situation where workers may be exposed to nitrogen dioxide and typical examples of that would be chefs working in an industrial kitchen, or workers in factories that have gas fired boilers. We have similar passive gas samplers that can measure ozone, that can measure sulphur dioxide, that can measure formaldehyde." There are currently two thousand samplers being worn around the world. The information collected from these will be used by environmental managers to ensure that we have clean air inside as well as outside.
