Background: Urban air pollution resulting from economic growth as well as urbanization impacts the health of inhabitants. This study aims to examine the spatial distribution of particulate matter (PM10) and the risk of exposure for the population in the Klang Valley, an urban conglomeration centred in Kuala Lumpur, Malaysia. Methods: The inverse distance weighted (IDW) interpolation technique in the ArcGIS platform was used to map the air quality from five air monitoring stations. Spatial statistics of the Global Moran's I Spatial Autocorrelation and Optimized Hot Spot Analysis were used to estimate the spatial clustering of PM10. The population-weighted exposure level (PWEL) technique was used to calculate the population density susceptible to PM10 and the AirQ+ model was applied to estimate the proportion of the adult population at risk of chronic bronchitis due to long-term exposure to PM10 concentrations in the Klang Valley. Results: The highest annual mean PM10 concentrations at the Klang station ranged between 80 and 100 μg/m3 from 2000 to 2009 and exceeded the New Malaysia Ambient Air Quality Standard (NMAAQS) and the World Health Organization Air Quality Guidelines (WHOAQG) levels of 40 and 20 μg/m3, respectively. The Moran's I results indicated that the statistically significant clusters of high PM10 in Klang present a health risk to the local community. The PWEL results showed that levels of PM10 in Petaling Jaya exceeded the WHOAQG limits, potentially posing a health risk to the high-density population. The AirQ+ model found Klang to be a significantly high-risk area for chronic bronchitis among the adult population with 804,240 people (with a relative risk of 1.85) in 2009. Conclusion: These high-risk values are due to rapid urbanization and high motor vehicle usage in the Klang Valley and therefore the impact of PM10 on the population needs to be reduced. This situation should be taken seriously by the Department of Environment and Kuala Lumpur City Hall in addressing air pollution issues through stricter rules on emissions and implementing low-carbon policies to improve the well-being of residents.

Home ownership is one key factor of the principles of livability towards achieving liveable city. In addition, there are also many factors affecting home ownership which includes income, location and accessibility factor. Various issues have been discussed by the Government of Malaysia in addressing the concern of home ownership, especially for the middle- and low-income groups in many cities in Malaysia. Using the case of Kajang city, this article aims to achieve the objective of identifying the major factors affecting home ownership for liveable city focusing the middle-income earners. Purposive sampling was used and in-depth interviews method were conducted with 41 potential homebuyer, 60 homeowners and 20 housing experts representing the Federal Government agencies, State Government agencies, Municipal Government, Developers, Banks and Real Estate-Related Consultant. The result of the study shows that the main factors affecting home ownership are income, housing loan scheme, location, government role, developer role, PR1MA affordable housing scheme, construction cost, Bumiputera quotas, lifestyle, quality of life, real estate investment and transfer, assessment/property tax, land ownership by foreigners and ownership title. The findings show that the Kajang City is an example of a city that can contribute to the affordable housing strategy requirements towards achieving liveable city. The findings also will help key stakeholder in addressing the main issues of housing affordability in the State of Selangor. [ABSTRACT FROM AUTHOR]

Malaysia is facing an increasing trend in industrial solid waste generation due to industrial development. Thus, there is a paramount need in taking practical actions and measurements to move toward sustainable industrial waste management. The main aim of this study is to assess practicing solid waste minimization by manufacturing firms. Analysis showed that majority of firms (92%) dispose of their wastes rather than utilize other sustainable waste management options. Also, waste minimization methods such as segregation of wastes, on-site recycle and reuse, improved housekeeping, and equipment modification were found to have significant contribution to waste reduction (p < 0.05). Lack of expertise (M = 3.50), lack of enough information (M = 3.54), lack of equipment modification (M = 3.16), and lack of specific waste minimization guidelines (M = 3.49) have higher mean score comparing with other barriers in different categories. These data were interpreted for elaborating on SWOT and TOWS (strengths, weaknesses, threats, and opportunities) matrix to highlight strengths, weaknesses, threats, and opportunities. Subsequently, ten policies were recommended for improvement of practicing waste minimization by manufacturing firms as the main objective of this research. [ABSTRACT FROM AUTHOR]
