Finding F-1224
“During the former observation term, all of the households showed significant decreases in the indoor concentrations of BTEX with passing time.”
Structure
- Factor
- Volatile organic compounds (VOCs)
- 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
- a stated direction without a number; both groups still had the plants during this term, so the decrease is not a contrast between them
