Odour Pollution Measurement from Refuse Derive Fuel Operations Using Odour Concentration Meter (OCM) XP-329

Odour perception is subjective and difficult to be accurately measured between individuals. Hence many studies on odour issues are more commonly pertain to its intensity, concentration, types, standards, measurement methods, law and impacts on physical and human environments. Nevertheless, odour analysis can be conducted empirically or based on human sensorial. Among major sources of odour pollution are animal rearing, oil palm and rubber mills, dumpsites, industries and sewage treatments. This study attempted to measure odour pollution generated by Refuse Derived Fuel (RDF) operation. The analysis was conducted at different times of day (morning, evening and night) and weather conditions (normal days and after rains). 10 sampling stations were selected for observations using the Odour Concentration Meter Siri XP-329 III.The results indicated that there existed different level of odour concentrations on normal days and after rains due to the influence of meteorological environment. Distance factors also influenced the odour concentrations, whereby gradually, the stations further from RDF operation recorded higher odour concentrations
