Formaldehyde is a colorless, flammable gas that can be carcinogenic to humans, and is a common additive to building materials and household products. Formaldehyde is also formed in the environment upon oxidation of a variety of hydrocarbons, including natural gas (methane). Symptoms of exposure to low concentrations of formaldehyde may include headache, nausea, throat and skin irritation, and exacerbated chemical sensitivity.

In Public Lab, we’ve been exploring low-cost methods for monitoring airborne concentrations of formaldehyde and low-cost methods for mitigating exposure to it.
