Amber glass vials (10 ml, VWR International, Radnor, PA, USA) were filled with 2.5 ml kiwifruit purée and 2.5 ml saturated NaCl solution and tightly closed using screw-caps with a PTFE/silicone septum seal (GRACE, Columbia, MD, USA).
Volatile organic compounds (VOCs) are lost from soil and sediment samples (hereinafter referred to as soil samples) due to volatilization and biodegradation during collection, storage and analysis. This leads to low-biased results. Some commonly used techniques are prone to relatively large losses and results that are potentially biased quite low.
