Abstract
The effect of increasing concentrations (0.01, 0.1, 1 and 5 mg l-1) of intact (FLT) and photo-modified (phFLT) fluoranthene and the duration of exposure (1, 2, 3, 5 and 7 days) on the chlorophyll fluorescence parameters (F0, FV/FM, and PhiII) of symbiotic algae in the thalli of two foliose lichens Lasallia pustulata and Umbilicaria hirsuta was investigated. In addition the FLT concentration in thalli of both lichen species was determined and a bioconcentration factor (BCF) was calculated. The results obtained demonstrated that the concentrations of FLT and especially phFLT (1 and 5 mg l-1) applied affected primary photochemical processes of photosynthesis in the algae of both lichen species. The F0 value increased and the FV/FM and PhiII values decreased. The fluoranthene content in the thallus of both lichen species increased with increasing FLT concentration in the environment.
Abstract (in Czech)
Byl studován vliv zvyšující se koncentrace intaktního (FLT) a fotomodifikovaného (phFLT) fluoranthenu (0.01, 0.1, 1 a 5 mg.l-1) a délky doby expozice (1, 2, 3, 5 a 7 dní) na parametry fluorescence chlorofylu (F0, FV/FM a PhiII) symbiotických řas ve stélce dvou foliózních lišejníků, Lasallia pustulata a Umbilicaria hirsuta. U obou druhů by stanoven obsah FLT a vypočten biokoncentrační faktor. Výsledky dokládají, že vyšší aplikované koncentrace FLT a zejména phFLT (1 a 5 mg.l-1) ovlivnily primární fotochemické procesy u obou lišejníků (zvýšení F0 a pokles FV/FM a PhiII). Obsah FLT ve stélkách lišejníků se zvyšoval s jeho zvyšující se koncentrací v prostředí.
