Key Points

The aim is to evaluate the accuracy of black carbon measurements when using filter-specific transmittance versus typical lab blanks.
Analyzed black carbon levels using reference transmittance measurements.
Compared results with those obtained from lab blanks and unloaded filters.
Assessed filter accuracy in lower concentration environments.
Using reference transmittance significantly improved eBC accuracy in low concentration settings.
Measurements using lab blanks showed lower accuracy compared to filter-specific methods.

Implication

Compares black carbon estimations using different filter analyses, indicating improved accuracy in specific conditions.

Abstract

values can be used to sufficiently characterize eBC; however, analyzing filters before sampling adds appreciably to the accuracy of eBC estimations in lower concentration settings.
