Observations on the suitability of the aethalometer for vehicular and workplace monitoring.
A field study was undertaken to evaluate the suitability of the aethalometer, an instrument capable of performing near-real-time measurement of low-level (10-1,000 ng/m3) airborne combustion products, for vehicular and workplace monitoring. Several technical limitations were identified: (1) there was no ready means for external calibration of optical measurements; (2) airflow rates were unstable; (3) effective range of concentrations was limited; and (4) the aethalometer demonstrated sensitivity to movement and vibration. Unless addressed, these limitations will restrict future uses of the aethalometer for vehicular and workplace monitoring.
