The study of interactions of drug residues with higher plants
Štrosová, Sofie ; Smrček, Stanislav (advisor) ; Soudek, Petr (referee)
Psychotropic agents are currently commonly used drugs. Their consumption increases dramatically, thus increasing the possibility of environmental contamination. Although these substances are largely metabolized, some of them are excreted through urine into municipal wastewater. Wastewater treatment plants only partially remove these micropolutants. Water effluent from wastewater treatment plants enter surface flows and through them pollutants are spread in the aquatic ecosystem and can contaminate terrestrial organisms. The interaction of drugs with plants provides us with information about the possible use of biotechnological decontamination technology - phytoremediation. In addition, the same process shows us the possibility of contamination of food chains of humans and animals, where these pollutants can cause changes in behavior and reproduction. The active substances trazodone and hydroxyzine are frequently prescribed drugs. The possibility of their phytoextraction and their uptake by the root system of corn plants (Zea mays) in an in vitro sterile model system was studied. Plants were cultivated on Murashige-Skoog medium. After adequate growth, medium with the studied pollutant with concentration 5 mg/L and 10 mg/L was added to the cultivations. The decrease in drug concentration in the...
