This study represents an early effort to understand the issues pertaining to odour that emanated from landfill sites. Admittedly, the issue itself was not new and had often been reported in the print and electronic media but thus far, however, there was no specific studies on this subject. The contribution of this study is empirical evidence that the bad odour coming from the landfill was disruptive to the everyday life of the local public. It was established that the bad smell was a constant nuisance to the outdoor activities of the residents. The “peak” malodour was more often experienced during the night necessitating residents to shut all windows and doors to reduce the sensing of the bad smell. The study also indicated that the periods and intensity of bad smell could be influenced by the weather, in particular, the wind direction. Hopefully this study will contribute some valuable information to the Malaysian Department of Environment in
formulating and developing guidelines on odour pollution from landfills.
