In environmental (in)justice communities, a major obstacle is the disparity between what scientific measurement can assess and the community’s embodied experiences with environmental burdens (see Brown and colleagues’ work on this for decades).  Additionally, the use of thresholds, geographically static measures of exposure and environmental pollution, and selective point assessments create what I call the “limitations of measurement.”  A sociologically and environmentally powerful citizen-science tool to address the “limitations of measurement” is the wearable Airbeam, which measures pollution and makes powerful visual displays of what people in a polluted community are literally breathing in.
