Compound-Specific Radiocarbon Analysis (CSRA) can be very helpful for sourcing contaminants produced by:

a)    Fossil and non-fossil feedstocks (e.g. PAHs from combustion processes)
b)    Natural and industrial sources (e.g. chlorophenols)

CSRA gives information of the carbon-14 content of the contaminant molecules; high levels indicate a modern source (“alive” - e.g. biofuel or wood combustion, natural production from a modern carbon pool) whereas low levels indicate an old source (“dead” - e.g. fossil fuel combustion or industrial chemical synthesis based on fossil petroleum).”

The research has received funding from the European Community's Seventh.
Framework Programme FP7/(2009-2012) under grant agreement no 212781.
