Any real-time monitor is available for identifying the marker of air pollution sources which emitted in the ambient air ex. ( Moter vehicles, road dust, industrial house emission). If any available, please given information.
There are quite a few real-time or near real-time (i.e. semi-continuous) instruments available to quantify aerosol and gas-phase components/markers. Examples would include the semi-continuous OC-EC analyzer (for carbonaceous aerosol), the PILS-IC/AIM/MARGA (for ionic species), the Aethalometer (for BC), the PX-375 (for metals), the PTR-MS (for VOCs), and gas analyzers for CO, SO2, NOx, and O3. In addition, aerosol mass spectrometers (AMS) can quantify aerosol components with a very high time resolution followed by data processing using a receptor model (PMF) to understand sources and atmospheric processes.
@Sayantan Sarkar. Thanks so much, sir,
But these instruments are not portable. If any portable instruments is available, so given information, sir.
Most of these instruments are portable (i.e., they can be used on moving platforms such as vehicles). If you mean "hand-held", then I'm afraid there aren't any such instruments to monitor pollution "markers." Some gas analyzers and dust monitors are hand-held, but they are not really useful for ambient measurements.
The Semicontinuous Elements in Aerosol Sampler (SEAS) is available from OEI. It can be mated to an inductively coupled plasma mass spectrometer, for sampling rates as high as 30/hr , and can be set up in a garden shed. To reap the maximum benefit, on-site meteorological measurements should be made. The current model, SEAS-IV,-plus, sits on a desktop and will come bundled with the third generation Pseudo-Deterministic Receptor Model (PDRM) and other analysis tools for source apportionment. A former chief of the EPA's source apportionment laboratory, called the results from SEAS-PDRM a "quantum leap in the field".
