Assement on level of indoor air quality at kindergartens in Ampang Jaya, Selangor, Malaysia

Abstract

This study identify the air pollutant that occurs in the kindergartens, to measure the le indoor air quality and also to analyze respiratory health symptoms. Three kindergartens were selected based on types of building J Fundam Appl Sci. 2017, 9(4S), 801-811 802The exposure history and respiratory health symptoms data among respondent in the study area were being collected by using questionnaire. Sampling for IAQ also being conducted and parameters involved for this purposed included carbon monoxide, carbon dioxide, temperature and humidity. Result shows that there is no significant difference of IAQ level between all kindergartens except for temperature and humidity (p≤0.05). The respiratory health symptoms also showed that only phlegm and chest illness show the significant difference in all kindergartens which (p≤0.05).

An overview of indoor air pollution in the Malaysian kindergarten environment

“…According to ICOP 2010, CO₂ exposure should not exceed 1000 ppm for an 8-hour period. Ten studies investigated indoor CO₂ with mean and median concentrations ranging between 537.04 ppm to 1680.35 ppm [31], [32], [34], [36], [39], [40], [43], [45]- [47]. Kindergartens in urban areas recorded high levels of CO₂ compared to kindergartens situated in suburban and rural areas [34], [36], [43].…”

“…The findings of this study coincided with Rahman et al [45] as all air-conditioned classrooms in three kindergartens also recorded CO₂ levels between 1068-1090 ppm with a capacity of 16, 19 and 24 children in each kindergarten. Most kindergartens with natural ventilation systems recorded CO₂ level below 1000 ppm [34], [36], [37], [43], [47]. However, Nahar and Salleh [46] found that a high density of 19-22 students in each classroom utilizing natural ventilation also contributed to high CO₂ levels.…”

“…Carbon monoxide (CO) is a toxic yet fairly unreactive gas. It is a colorless, odorless, and tasteless gas created by the incomplete combustion of natural gas, diesel, or gasoline in automobile engines [48].Indoor CO concentrations in kindergarten classroom was reported in eight articles [32], [34], [36], [37], [40], [43], [45], [47]. Studies report indoor CO mainly comes from outdoor sources related to traffic.…”

Kindergartens in urban areas recorded high levels of CO₂ compared to kindergartens situated in suburban and rural areas [34], [36], [43]. Some studies reported high CO₂ concentrations in kindergartens classrooms exceeding 1000 ppm during class activities [31], [39], [40], [45].…”

A study on air pollution concentration at Desa parkcity construction site

“…The Air Quality [17][18][19][20][21][22][23][24][25] Guidelines set for the first time a guideline value for particulate matter and the aim of the guidelines is to achieve the lowest concentrations of pollutant in atmosphere as possible [11].…”
