Below is the interum report of the NSF-funded SMART-FORM project, lead by Karen Dannemiller of Ohio State University and with Public Lab as a Co-PI.

We spend about 90% of our time indoors, where we are exposed to a complex mixture of chemicals, including formaldehyde. Formaldehyde is a known carcinogen and exposure can also result in eye, nose, and throat irritation. Currently, concerned members of the public have no method to inexpensively and reliably measure the formaldehyde concentration in their environment. Current methods require expensive analytical instruments, are prone to contamination, suffer from interfering compounds, or are difficult to complete. The goal of this work is to develop and launch an accessible, inexpensive and reliable formaldehyde detection technique for use in community science and by the public writ large. We have achieved partial completion of each of our three objectives as described below and will continue to pursue completion over the following year:
1) develop a colorimetric formaldehyde detection badge and novel Smartphone-based App to read the badge.
We have completed production of the beta version of the Android app and the iOS beta version is nearing completion. Community feedback has been and will be incorporated in the design throughout development. Independent verification at the Building Energy and Environmental Systems Laboratory (BEESL) will confirm that badges function properly. Environmental chambers have been commissioned to perform the verification tests planned for the Fall of 2017.
2) ensure adoption of the new technology by the community science community and concerned community members.
We have completed our initial community survey through which respondents provided information about their interests, concerns, and input for the development and design of the app. We are currently preparing for a community beta test of the app. Later we will also complete a community case study using the final version of this novel formaldehyde detection system.
3) To make the collected data publicly available to community scientists for interpretation.
We have generated interest in the app through conversations with a concerned community, social media, email, and a blog post. We will ensure that data and information are publicly available as described in the proposal.
Intellectual merit: We have demonstrated a new inexpensive method to measure compounds of concern in the indoor environment using a smartphone app to quantify the extent of color-change reactions. Concerned members of the public and community scientists will be able to use this technology to easily and inexpensively measure the formaldehyde concentration in their environment. This technology has the potential to expand to measure other compounds of concern.
Broader impacts: We have prioritized community engagement in the project. We have already incorporated community feedback into the app design and will continue to do so for the remainder of the project. We are actively working with community members to promote community science.
Next steps for Public Lab include: beta testing the app, open sourcing the app in the Public Lab GitHub, and designing and implementing the case study in Waycross GA.
