Formaldehyde
formaldehyde

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. For a quick summary of formaldehyde exposure basics, please see the [ASTDR’s ToxFAQs for Formaldehyde](https://www.atsdr.cdc.gov/toxfaqs/TF.asp?id=219&tid=39). For much more in-depth information, please see the [ASTDR’s Toxicological Profile for Formaldehyde](https://www.atsdr.cdc.gov/toxprofiles/tp.asp?id=220&tid=39). 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. ### Formaldehyde projects Projects related to formaldehyde monitoring and exposure mitigation can be found on the following wikis. Low-cost monitoring of airborne formaldehyde using colorimetric tubes: https://publiclab.org/wiki/formaldehyde-test-kit Low-cost monitoring of airborne formaldehyde using a passive badge sampler and smartphone app: https://publiclab.org/wiki/smart-form Personal exposure to formaldehyde (and information about exposure): https://publiclab.org/wiki/formaldehyde-exposure Low-cost remediation or airborne formaldehyde: https://publiclab.org/wiki/diy-indoor-air-quality-remediation-kit ### Current formaldehyde research in Public Lab Follow active development on [the tag 'formaldehyde.'](/tag/formaldehyde) You can also [subscribe](/subscriptions) to to the formaldehyde tag to get email updates when a research note, wiki, or question gets tagged as related to formaldehyde. **** ### Questions in Public Lab related to formaldehyde [questions:formaldehyde] **** ### Activities to try in Public Lab related to formaldehyde [activities:formaldehyde] **** ...
