^aFruit samples like plum and apple was not added in Table as no MT was detected in headspace collected from those samples;

^bConcentration of MTs in headspace (0.25 L) collected from F/P/V samples;

^cSample mass placed on impinger: 1 and 10 g, respectively;

^dSample mass placed on impinger: 1 and 10 g, respectively;

^eNot detected: MDL values are given at “µg” unit;

^fEmission rate = [Total mass of MTs in 0.25 L headspace / Sample (F/P/V) mass placed on impinger].
