Finding F-1223

“Although formaldehyde failed in performing various tendencies in its indoor concentration by indoor plant placement, BTEX succeeded in showing significant differences in their indoor concentrations according to placement.”

House-plant placement for indoor air purification and health benefits on asthmatics… (2014). Environmental health and toxicology. Page 4. CKB 6935

Structure

Factor
Formaldehyde (CH₂O)
Intervention
Indoor plants (phytoremediation)
Population
asthmatics and their households
Setting
home, KR
Study design
quasi-experimental study in the homes of asthmatics in Korea over two observation terms: households of continuation kept the indoor plants for both terms, households of withdrawal kept them for the first term and passed the second without any plants; formaldehyde and benzene, toluene, ethylbenzene and xylene were measured indoors, with peak expiratory flow rate twice a day and an asthma-specific quality of life questionnaire, compared with the Mann-Whitney test (class 3)
Caveat
the sentence is the study's statement that the plants made no difference to formaldehyde; the direction of the difference it reports for the other compounds is not stated in the sentence, so a sibling row from the abstract carries it

A Finding records what one published document states, verbatim and with its page. It is not a conclusion of Coridum; see the Claims that build on it.
