Factors affecting air quality management in Bangkok

Abstract

The purposes of this mixed-methods research were as follows: (1) to study the factors affecting efficient air quality management in Bangkok; and (2) to suggest the efficient air quality management in Bangkok. For quantitative research, the samples were 400 people living in Bangkok selected by using Stratified Sampling. The data collection tool was a questionnaire. Factor analysis and Orthogonal Rotation method: Equamax were used for data analysis. For qualitative research, the key informants were 20 specialists obtained by purposive sampling. Data were collected using semi-structured interview guide and in-depth interview. Data were analyzed following the concept of Saldana [1].

The results of the study were: (1) factor analysis shows Bartlett's Test of Sphericity (0.000) and KMO (0.970). Twelve factors were extracted. The element of Standard Strategic Management have the highest level of Eigen values at 36.194; and (2) several methods of air quality management are available with their own strengths and weaknesses. Each method is suitable for different air pollution cycle and contextual use in different areas. It is recommended that air quality management methods be chosen depending on the main mission to protect the health and well-being of the people. All works should be integrated in all aspects and in depth. A strategic plan should be developed to cover every cycle of air pollution.
