Study on Air Quality and Influences on Human Respiratory Health Among Residents Who Occupy Buildings at Former Landfill Site

The objective of this study was to determine the influence of air quality on the residents' respiratory health that occupy buildings at the former landfill site at Taman Sri Manja, Petaling Jaya, Selangor compared with the control which in PPR Air Panas located at Setapak, Kuala Lumpur. Methods that are used for this study are gas sampling using aeroqual and multi-log gas detector. High-volume sampler was used for PM sub( 10) determination. Results showed that all the parameters including gases, PM sub( 10), heavy metals and total count of microbes under the estimated standard value have no significant difference between the case study and control. Respiratory symptoms score also showed significant differences between respondents at case (1.38 plus or minus 0.36) and control (1.30 plus or minus 0.37) location. Although there was significant difference between the average value of peak flow meter and the expected value, but the value for both case and control study are between the range of 20% under the expected value which indicated normal respiratory health status.
