Finding F-1228
“The household of continuation showed a continual decrease in the indoor concentrations of volatile organic compounds (VOCs) during the entire observation period, but the household of withdrawal performed an increase in the indoor concentrations of VOCs, except formaldehyde and toluene during the latter observation term after the decrease during the former observation term.”
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; formaldehyde and toluene are the exceptions the sentence names, and their concentrations kept falling
