Finding F-0326

“In second place, pine showed relatively high emissions (0.0127 ± 0.002 μg g−1 ), followed by birch (0.0109 ± 0.001 μg g−1 ) and MDF (0.0107 ± 0.0002 μg g−1 ), whose values were statistically close within the margin of experimental error.”

Structure

Source: Wood
Factor: Formaldehyde (CH₂O)
Setting: laboratory (desiccator), MX
Study design: laboratory desiccator-method comparison (JIS A 1460 type) of formaldehyde emissions from six interior wood materials: medium-density fiberboard, melamine-faced board, pine, birch, oak and alder (class 4)
Effect: emission-rate 0.0127
Caveat: emission per gram of material in a desiccator, not a room concentration; spread printed as ± without naming the measure
