“…It is possible that any volatile, labelled compound can contribute to elevated PM samples. The fullerene soot mixed with iron powder that we use to monitor aerosols in AMS prep labs is essentially PM packed into an AMS target [19,20]. The lab aerosol monitors detect 14 C releases as subtle as defrosting freezers holding archived tissues from 14 C bioAMS studies [19].…”

The lab aerosol monitors detect 14 C releases as subtle as defrosting freezers holding archived tissues from 14 C bioAMS studies [19]. We have measured elevated aerosol monitors and connected it to the use of 14 C-benzene in a building near our preparation labs [19].…”

“…All medical waste and low-level radioactive waste incinerators are potential sources of tracer 14 C in PM since isotopic signatures are carried from fuel through the combustion process to PM [18]. Additionally, hood exhaust from laboratories using 14 in fullerene soot aerosol monitors deployed in and around AMS facilities [19,20]. Hence, ambient PM can adsorb elevated 14 CO 2 from incineration of low-level radioactive waste or tracer 14 C emissions from fume hoods.…”

Fire-derived, pyrogenic carbon (PyC), sometimes called black carbon (BC), is the carbonaceous solid residue of biomass and fossil fuel combustion, such as char and soot. PyC is ubiquitous in the environment due to its long persistence, and its abundance might even increase with the projected increase in global wildfire activity and the continued burning of fossil fuel. PyC is also increasingly produced from the industrial pyrolysis of organic wastes, which yields charred soil amendments (biochar). Moreover, the emergence of nanotechnology may also result in the release of PyC-like compounds to the environment. It is thus a high priority to reliably detect, characterize and quantify these charred materials in order to investigate their environmental properties and to understand their role in the carbon cycle.Here, we present the benzene polycarboxylic acid (BPCA) method, which allows the simultaneous assessment of PyC's characteristics, quantity and isotopic composition ( 13 C and 14 C) on a molecular level. The method is applicable to a very wide range of environmental sample materials and detects PyC over a broad range of the combustion continuum, i.e., it is sensitive to slightly charred biomass as well as high temperature chars and soot. The BPCA protocol presented here is simple to employ, highly reproducible, as well as easily extendable and modifiable to specific requirements. It thus provides a versatile tool for the investigation of PyC in various disciplines, ranging from archeology and environmental forensics to biochar and carbon cycling research.
