Impact on the amount of CO2 in indoor area depending on the temperature of Dieffenbachia

Abstract

Today, at least 80% of human life spends time in closed areas; indoor air quality directly affects people's health and performance. In particular, when CO2 rises above certain levels, it causes many discomforts such as headache, dizziness, fatigue, concentration disorders, throat and nose irritation, nasal discharge, coughing and eye runoff on certain levels. The most important factor affecting the amount of CO2 in indoor area is live metabolic activities. The amount of CO2 is increased by respiration that decreases with photosynthesis. Therefore, plants can be used indoors to reduce the amount of CO2. However, since there is not enough information on this subject, plants can not be used efficiently and consciously to reduce the amount of CO2 in indoor area. In this study, it was aimed to determine the effect of Dieffenbachia which is one of the most commonly used plants as an indoor ornamental plant depending on the temperature of the effect of CO2 on indoor area. As a result of the study, it was determined that the breathing of the Dieffenbachia in the dark area is insignificant depending on the temperature. However, the highest efficacy is observed at temperatures of 23-24°C in the presence of light. The results of the study shows that the rate of photosynthesis at temperature of 30°C was found to be lower than 20°C even though it was higher than 15°C.
