Editorial summary
The researchers treated wood with calcium or magnesium hydroxide nanoparticles to create an alkaline reserve without applying an appearance-changing coating, aiming to suppress acid vapours that corrode historic organ pipes. FLEC measurements found acetic-acid emissions below 70 µg m−2 h−1 from treated wood during the first thirteen months, compared with 200–400 µg m−2 h−1 from untreated wood.

FLEC use
Direct FLEC measurements
FLEC was the emission test cell used to quantify VOC and acetic-acid emissions from nanoparticle-treated and untreated wood over the study period.
