Abstract

In the last 50 years, air pollution has undergone rapid changes and increased dramatically. Earlier in Malaysia, little attention was given to the environment concerns until there are a few series of high particulate event occurred. Among all environmental pollution problems, air pollution is stated to cause the greatest damage to health and loss of welfare from environmental causes especially in Asian countries including Malaysia and air pollution, whether it short- or long- term impacts can affect human health, well-being and environment. Researches indicated that indoor air pollutants exposure is greater than outdoor exposure for many people. Indoor air pollutants have the potential to cause transient morbidity, disability, disease, and even death in extreme cases. Thus, this study examined the concentration of several indoor air pollutants which are nitrogen oxides, sulphur dioxide and ozone in the enclosed KLCC car park area. Enclosed car park was chosen as the location of sampling because of the poor air quality in the car park. This issue has been raised up frequently by the community. These data were collected hourly by using GrayWolf Advanced Sense Direct Sense; Toxic Gas Test Meters for two weeks from 0800 to 1700 hour. Then the data was analyzed by using time series model to observe the trends of air pollutants in the sampling location which is at the determining the concentrations of the samples at the selected sampling location which is at the PETRONAS Twin Tower basement car park. From the analysis, the objectives of the study have been achieved. Firstly, the concentration of NOx will be the highest among the three air pollutants. Secondly, there was formation of O3 recorded at the sampling area. The O3 might be infiltrated from the outside surrounding into the car park and there are also several other factors that can cause O3 emissions. The concentration of NO2 and SO2 recorded in this study has exceeded the standard limit set by MAAQG thus action might have to be taken by the KLCC parking management to enhance the air quality in the enclosed car park.
