Screening of semi‐volatile compounds in plants treated with coated cerium oxide nanoparticles by comprehensive two‐dimensional gas chromatography

Literature data about semi-volatile organic compounds in plants and the effect of cerium oxide nanoparticles on them are scarce. Surface modification may change nanoparticle-environment interaction, therefore affects plants. In this research, uncoated glucose-, levan-, pullulan-coated were used for wheat pea treatment during growth. The aim was screening from plants’ shoots using comprehensive two-dimensional gas chromatography–mass spectrometry, a powerful separation technique allowing to reach unique resolution, investigation qualitative changes after with coated nanoparticles. results analyzed by identification individual peaks fingerprint analysis image processing. Wheat samples contained higher number (108) compared (77) but less affected treatments highest detected levan- nanoparticles, levan-coated This article reports successful application profile presented only as categorical variables images inter-cultivar recognition. method be useful nanoparticles’ effects different
