Short summary

Determining benzene in ambient air is mandatory in the European Union. The reference measuring technique is by gas chromatography (GC), and a photometric ionisation detector is recommended. This study shows that the simultaneous presence of benzene and tetrachloromethane causes a significant decrease in GC–photoionisation detector (GC-PID) readings. Given the importance of this behaviour, a possible mechanism was proposed. This study highlights the uncertainty of measuring benzene with a GC-PID.
