Abstract
Sick-house syndrome widely occurs in general domiciles. Its cause is from
various types of chemical substances generated from building materials. The
airtight structure is also one of the main causes for the syndrome. The most
prevalent chemicals are formaldehyde, toluene and xylene. It is well known that
plants have purification capabilities for these chemicals in an indoor
environment. It is strongly desired to reduce the pollution level for multiple
chemical sensitivity in domiciles and buildings. Foliage plants are very effective
in reducing the pollution concentration. In this study, the purification
characteristics of golden pothos for polluting chemicals emitting from a piece of
building board are examined using a tin oxide gas sensor. The experiments are
carried out in an airtight chamber of 200 liters. The number of plant pots were
also changed from 0 to 3 in the experiments. As for the results, pothos had high
purification capabilities for those chemicals and the capabilities increased as the
number of pots were added. The purification rate reached almost 100% at over
three pots in the chamber experiment. The approximate function of the
purification characteristic is derived using an exponential function. The system
can introduce the pollution level in an indoor environment using this expression.
It is felt that this model can be effective in estimating the pollution level and the
design of an indoor environment.
