background: human hair can be used as an inexpensive and accessible adsorbent to remove a variety of pollutants from air. although several studies have been done on removal of formaldehyde from wastewater by human hair, to date no study has investigated using hair to remove formaldehyde from air. therefore, the aim of this study was to remove formaldehyde from synthetic contaminated air by a re...

The objective of this study was to manufacture particleboard made from UF with low formaldehyde (E1) for use in indoor environments. The influence of UF in particles on the formaldehyde emission and its mechanical properties were investigated. The experimental results showed that the formaldehyde emission released decreased linearly with consumption UF-low formaldehyde- particle. Formaldehyde e...

BACKGROUND Positive patch test reactions to formaldehyde-releasers in patients co-reacting to formaldehyde are often ascribed to formaldehyde allergy. However, the formaldehyde content of patch test materials has not been investigated. OBJECTIVES To demonstrate and quantify free formaldehyde in commercial patch test materials and in prepared aqueous solutions of formaldehyde releasers. MATE...

HeLa cells were exposed to formaldehyde and its metabolic derivatives, methanol, formic acid, and acetaldehyde, to investigate that the toxicity of formaldehyde is not caused by the chemical group. After 1 h of treatment with formaldehyde, mitochondrial assays showed that low concentrations (e.g. 10 μmol/L) of formaldehyde promoted growth of the HeLa cells, while higher concentrations (e.g. ≥62...
