The Environmental Defense Fund has released its report of an ERG-led study examining the market for personal chemical exposure monitors (PCEMs). PCEMs are an emerging class of “wearable” devices targeted at consumers who wish to understand their exposure to chemicals during everyday activities. These devices may also have application in the workplace—monitoring worker exposure to chemicals in industrial or other settings—and among first responders. To help inform PCEM developers about the market, ERG conducted a survey with a nationally representative sample of 616 people. The survey elicited data about the features consumers prefer in a PCEM and the price they would be willing to pay for devices with different feature sets. ERG also interviewed 16 stakeholders from the developer, user, and investor community and presented their perspective as part of the report.
