22-mL glass vials with screw caps with septum (Supelco,Bellefonte, PA, USA), were used to carry out HS sampling.A SPME assembly with replaceable extraction fibers coatedwith polydimethylsiloxane–divinylbenzene (PDMS-DVB, Stable-Flex 65 m, Supelco) were employed for extraction. Before usinga new fiber, it was conditioned during 1 h in the GC injector port at250◦C.
