초록

This study aims to look into the effects of formaldehyde and dusts removal in ecological zones, and it was based on ecological zones of the Heukseok subway station with the skylight in order to examine the degree of the effects. As the result, the formaldehyde concentration in the ecological zone and the zones 10m and 20m away from the ecological zone was around 20.7ppb, 21.2ppb and 26.8ppb and this showed the farther it was from ecological zones, the higher the concentration became. And the dusts concentration in the ecological zone and the zones 10m and 20m away from the ecological zone was around 18.0㎍/㎥, 19.2㎍/㎥, and 67.4㎍/㎥, and this showed the farther it was from ecological zones, the higher the concentration became.As to temperature and humidity, there was no big change according to ecological zones and distance by cooling and ventilation facilities that are now operating in subway stations. However, the humidity of ecological zones appeared highly as 3-4% from 11:30 a.m to 5:30 p.m when photosynthesis and transpiration occurs actively due to inflow of natural light. In addition, as the result of survey on daily variation of formaldehyde in ecological zones, the formaldehyde concentration was lowest during that time. Therefore, the ecological zones in underground spaces seem to make indoor air fresh by reducing formaldehyde and dusts and increasing humidity, and it seems to affect even 10m away space.
