An organization page for RISD-led grassroots detection of H2S research. [Google Doc](https://docs.google.com/document/d/11GbzS4T1AXwvQcSOSOKSQnltmJ3wmhDZjWTMkvP_Zl4/edit?hl=en_US) ##Framing the problem## * where is the issue located? how can we get there and with whom do we collaborate? * https://www.flickr.com/photos/recordandremember/6151719485/in/set-72157627674148174 * what is the information that’s missing? How will it change the situation? * what are they key parameters: * what intensities & exposure times are harmful to humans or the environment? * http://publiclaboratory.org/notes/warren/9-6-2011/hydrogen-sulfide-detection-fart-detector * where can it be detected? by smell range? * how long does it take? * how fast does it move/change, or how large an area does it affect? * what kind of detection? presence/absence? direction of flow? intensity or spot source? * what equipment is available today, and who has access to it? How much does it cost and what is its sensitivity/latency? How much does it weigh and how does it work (air grab sample, continuous flow, soil sample?) * Google Shopping - as low as $109 * who are the potential users? What should the output data look like? Graphs, logs, lights, images? * what are the data’s uses/outcomes? Legal? Avoidance? Remediation? Regulation? * are there alternative means of detecting which are dramatically different/cheaper? * silver film tarnishes with exposure to H2S
