A previous paper (Quincey, 2007) described a simple quadratic relationship between OECD Black Smoke Index (I(BS)) and Black Carbon (aethalometry) measurements of ambient particulate samples (C(BC)): C(BC) = root 4.18I(BS) + 59.6 - 7.72, based on their common link to optical absorption coefficient, supported by a single dataset. Further parallel datasets are presented here that support the general validity of the relationship, while highlighting limitations to the traditional Black Smoke method at kerbside sites, and variations between sites. The opportunity is taken to clarify some confusing aspects concerning published standard methods for Black Smoke. Crown Copyright (C) 2011 Published by Elsevier Ltd. All rights reserved.
