The objective of this study was to develop and apply a procedure
to determine products of the petroleum industry in aqueous samples
using headspace SPME with a fiber for sampling and GC–FID for analysis.
Parameters of extraction (time, temperature, agitation rate, content
of salt), and the time and temperature of desorption in the gas
chromatograph injector were selected.
The procedure was validated and applied to analyze water contaminated by unleaded petrol and
water used to extinguish a simulated fire.
