Pyrethroids in abiotic and biotic environmental matrices
 Kociánová, Veronika ; Vondráčková, Ilona (referee) ; Vávrová, Milada (advisor)
Synthetic pyrethroids form the main class of synthetic organic insecticides, which are applied in agriculture, household, and public health. Synthetic pyrethroids account form more than 30% of insecticide use worldwide, thereby they gradual replace chemicals of insect pest control as organochlorine and organophosphate insecticides. Pyrethroids are synthetic derivates of natural pyrethrins. In comparison with natural pyrethrins have pyrethroids greater photostability, greater resistence to degradation and greater insecticidal activity. Pyrethroids are labeled as potent neurotoxicants, which interact with sodium channels. Pyrethroids occur in abiotic and biotic environmental matrices. In this study we focused on the determination of this compounds in environmental water samples by GC-ECD, because of the pyrethroids contain atoms of nitrogen and halogens in their structure.
