    (Thai Society of Higher Eduation Institutes on Environment, 2014) Oliver Ling Hoon Leh; Siti Nur Afiqah Mohamed Musthafa; Noralizawati Mohamed
    In line with the global trend of urbanisation, large population are staying in urban areas as compared to rural. However, urban area /region is always related to higher air pollution level as compared to less developed area/region. The major contributors of air pollution are mobile sources (transportation) and stationary sources (e.g. industry and power plant). Thus, the issue of air pollution is potentially caused by human choices and activities, and potentially affecting the human health. Therefore, the relationship between the urban activities (land use coverage/distribution) and air quality level should be well understood. It helps the urban managers, planners and all parties in constructing healthier urban policies. A study of air quality and the relationship with urban land uses was carried out in Malaysia's urban growth region of Klang-Shah Alam-Petaling Jaya. Air quality data was analysed in Air Pollution Index (API) with the classification of good, moderate, unhealthy, very unhealthy and hazardous levels.

    Urban environmental health: Respiratory illness and urban factors in Kuala Lumpur city, Malaysia
    (Thai Society of Higher Eduation Institutes on Environment, 2011) Oliver Ling Hoon Leh; Shaharuddin Ahmad; Kadaruddin Aiyub; Yaakob Mohd Jani; Ting Kien Hwa
    With increasing urbanisation, more people are now staying in urban built environments, even though the conditions of the urban environments may not be conducive to urban residents' health. However, with the lack of health data of urban residents, very few studies have been conducted to examine the relationship between urban factors and city residents' health especially in developing countries. Therefore, the objectives of this paper are to examine the rate of respiratory illness (acute respiratory infection and asthma) among residents of Kuala Lumpur City and also to investigate the relationship between the respiratory health rate and urban factors.,
