Notes:
Abstract Diterpenoids present in atmospheric particles produced by slash burns were analyzed by capillary gas chromatography-mass spectrometry. This suite of compounds, originating in the resinous higher plants which were combusted, was comprised of reaction intermediates in the thermal transformation sequence of components such as abietic acid and dehydroabietin to retene. This sequence parallels the diagenetic alteration/decomposition processes noted in sedimentary records. Since global transport of combustion aerosols has been well documented, it is likely that the thermally-altered diterpenoids elucidated in this study can be deposited directly to sedimentary sinks.
