![]() ![]() The World Health Organization recognizes air pollution as the single largest global environmental health threat accounting for millions of premature deaths annually ( Lelieveld et al., 2015 World Health Organization, 2021). This work summarizes the protocols in use, provides an overarching perspective on the state-of- the-art and recommendations for certain aspects of future method development. Here, we review the existing analytical techniques for the isolation of BC from a filter matrix for conducting 14C-based investigations. The radiocarbon isotope ( 14C or carbon-14) fingerprinting allows for an unambiguous and quantitative constraining of the BC sources and is therefore a well-popularized method. ![]() An accurate knowledge of BC emitting sources is necessary for devising appropriate mitigation strategies and policies to reduce the associated climate/environmental burden. Black carbon (BC)-a product of incomplete combustion-is a potent climate warming agent and one of the central components to this issue. ![]() The issue of air pollution is often closely linked to carbonaceous aerosols, the assessment of climate/air quality/health impact of which remains associated with large uncertainties. 2GEOTOP/ Université du Québec à Montréal (UQAM), Montréal, ON, CanadaĪir pollution, a complex cocktail of different components, exerts an influence on climate/human health both locally and away from source regions.1Institut Des Géosciences De l'Environnement (IGE), University Grenoble Alpes, CNRS, IRD, Grenoble INP, Grenoble, France. ![]()
