Active and passive smoking – New insights on the molecular composition of different cigarette smoke aerosols by LDI–FTICRMS

摘要: Abstract The aerosol generated when a cigarette is smoked significant indoor contaminant. Both smokers and non-smokers can be exposed to this class of pollutants. Nevertheless, they are not the same kind smoke. active smoker breathes in mainstream smoke (MSS) during puff, whereas passive inhales only by lit between two puffs (SSS) but also exhaled (EXS). fraction EXS has until now been poorly documented; its composition expected different from MSS. This study aims investigate complex better understand difference exposure smokers. To address this, in-situ laser desorption ionisation Fourier transform ion cyclotron mass spectrometry (LDI–FTICRMS) was used characterise Results clearly indicated many similarities samples differences with MSS SSS aerosol. comparison allowed chemicals retained smoker's lungs identified, convolution compositions were considered relevant exposition smoker. As consequence, thought mainly polar unsaturated oxygenated nitrogenated organics, compared highly compounds
