Abstract

Atmospheric aerosol samples collected simultaneously on four different filter media support the hypothesis that reflectance, as measured by the British “Smoke” method, is controlled by the optical absorption coefficient of the aerosol. An additional comparison shows that the British “Smoke” measure may be used to estimate concentrations of sub-μm, particulate, elemental carbon. Poorer correlations are suggested for the mass concentration of the particles suspended in air.

      Previous studies have explained that fibrous filters allow the particles to become partly or completely embedded (Bond et al., 1999). The penetration of particles into the filters causes multiple scattering within the filter (Presser et al., 2014; Davy et al., 2017) and may cause the filters to be more reflective for a given aerosol loading than if the particles were retained on their surface (Edwards et al., 1983). This occurs on matted filters, where the particles appear to be distributed discretely over the uneven topography of the matted surface (Presser et al., 2014).

      OECD (1964) and BSI (1969) provided a correction factor of 0.92 when the face velocity was 25% of the standard value and a correction factor of 0.80 for 6% of the standard, indicating that the effect is not excessive. Additionally, Edwards et al. (1983) found consistent relationships between reflectance and elemental carbon between two samplers with a factor of four differences in face velocity, for Whatman paper filters. It is unlikely, therefore, that face velocity would be a major constraint in applying Equations (2) and (3) and Table 6 factors to filters collected under different sampling regimes, although this would need to be confirmed experimentally.

      This method assumes that light at any wavelength is absorbed only by BC. Prior work (Edwards et al., 1983, and reference therein) has demonstrated that SSR measurements can be a good proxy for elemental carbon concentrations in PM filters; however, the standard EXPOLIS method for using the SSR has the device directly touching the PM on the active area of the filter and measures the filter in five locations, leading to potential mass loss and/or cross contamination. To overcome contamination issues, the Columbia University group designed and successfully applied a filter holder that touches only the outer plastic ring, holding the filter in a fixed flat geometry and 2.5 mm away from the head of the SSR (Kinney et al., 2002; van Vliet and Kinney, 2007).

      The precision of the BC was estimated to be within 4–9%, depending on the mass loading on the exposed filter. The absolute accuracy of the reflectometer system for BC estimates is less uncertain, and comparisons of this technique with thermal optical reflectance measurements have been made (Edwards et al., 1983; Horvath, 1997a,b). Multielemental analyses of the samples collected during the above cited time intervals were made using proton induced X-ray emission (PIXE) at the Institute of Geological and Nuclear Science (GNS), New Zealand.
