Toxicity assessment of different types Cd based quantum dots for model plants

Popis výsledku v původním jazyce

We report on the toxicity and bioaccumulation of different types of Cd-based QDs for a selected model plant organism. After a certain exposure, we monitored the growth of roots and dry biomass of roots as a macroscopic toxicity end-point. Then we determined the total Cd content in different plant parts by Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). Consequently, the plant roots were inspected by the fluorescence microscopy to determine if Cd-based QDs are adsorbed on the root surface and how it depends on the QD type. Selected QDs showed different toxicity in correspondence with different Cd bioaccumulation patterns. We discussed possible hazardous effects of Cd-based QDs for selected plant as well as the environmental implications of the exposure to Cd-based QDs.
