Particulate matters from ambient air samples have been collected using two techniques with different equipment: High Volume Air Sampler (volume air samplers) and Gent Stacked Filter Unit Sampler at the similar location and period. As a comparison from both sampling techniques, heavy metal concentration, Lead (Pb) has been compared in accordance with the parameters of heavy metals in the appendix to Government Regulation No. 41 of 1999 on Air Pollution Control. Total Suspended Particulate (TSP) which collected using a high volume air sampler were particulates with diameter size 0-100 μm, and the lead (Pb ) concentration in these samples was analyzed using Atomic Absorption Spectrometry (AAS). Gent Stacked Filter Unit Sampler collected two size fractions of particulates with diameter size 0-2,5μm or PM 2.5 and particle size 2,5-10μm or PM 2.5-10 , the lead concentration in these samples were analyzed using Particles Induced X ray Emission (PIXE). The objective of the study is to obtain the ratio of the results from the measurement using the High Volume Air Samplers and Gent stacked filter units sampler. The results of the measurement during 25th August to 25th September 2008 showed a strong correlation between concentration of Pb in PM 2,5-10 compare to Pb in TSP have with R 2 values of about 0.7. Hopefully, this data can be used as a reference by other laboratories .
