Description Polycyclic aromatic hydrocarbons (PAHs) participate in a considerable extent of increasing anthropogenic pollution in the environment. Plants have ability for their bioconcentration and bioconversion. The aim of this study was to use the biochemical and physiological parameters of plants as early indicators of phytotoxic effect of FLT. Pea seeds germination and seedlings growth were evaluated after 3 and 7 days, respectively. Plants were cultivated in Reid-York nutrient solution without or with fluoranthene (FLT; 0.1, 1 and 5 mg/l) for 20 and 27 days. FLT presented both in the environment and plant tissues caused changes not only on subcellular level (PSII, photosynthetic pigments, GSH) but also on level of whole plant organs (biomass production). Changes of values of chlorophyll fluorescence parameters and GSH content show an influence of FLT on structure and function of membranes accompanied by free radicals formation.
