4. MEASUREMENT OF RESPIRABLE SUSPENDED PARTICULATE MATTER (PM10) IN AMBIENT AIR (CYCLONIC FLOW TECHNIQUE) 1.0 TITLE Method for measurement of Respirable Suspended Particulate Matter (PM10) in ambient air (Cyclonic Flow Technique). 2.0 PURPOSE The purpose is to lay down an uniform and reliable method for measurement of PM10 (Particulate matter less than 10 µm diameter) in ambient air. 3.0 PRINCIPLE Air is drawn through a size-selective inlet and through a 20.3 X 25.4 cm (8 X 10 in) filter at a flow rate which is typically 1132 L/min. Particles with aerodynamic diameter less than the cut-point of the inlet are collected by the filter. The mass of these particles is determined by the difference in filter weights prior to and after sampling. The concentration of PM10 in the designated size range is calculated by dividing the weight gain of the filter by the volume of air sampled. 3.1 Other Analysis - Depending on the type of filter media used, filter samples can be analyzed for lead, iron, organic and elemental carbon, extractable organic material, elements, radioactive materials, inorganic compounds, and single particles. 3.2 Range and Sensitivity 3.2.1 Lower Quantifiable Limit - For a 24-h sample duration at 1000 L/min, the detection limit is determined by the reproducibility of the filter weight difference which shows a standard deviation (sigma) of approximately + 2mg. The threesigma detection limit is then approximately 3.5 µg/m 3 . The three-sigma lower quantifiable limit depends on the filter used and may be as high as 5 µg/m 3 . 3.2.2 Upper Quantifiable Limit - For a 24-h sample duration at 1000 L/min, this limit is in the range of 400 to 1000 µg/m 3 . The exact value depends on the nature of the aerosol being sampled, very small particles will clog the filter at a relatively low mass loading while larger particles will fall off during sample transport at high concentrations. 4.0 SCOPE This method is applicable for measurement of PM10 in the ambient air. 79
