Title of diploma thesis: Monitoring of albendazole transfer from ovine faeces to fodder plants by LC-MS In general, drugs might be a significant source of pollution in the environment especially drugs with high persistence. Albendazole (ABZ) belongs to a benzimidazole group of anthelmintic drugs. These drugs are regularly and frequently used to limit and treat parasitic infections in animals. ABZ enters the environment via animal excrements and it can have negative effects on non-target organisms. Laboratory experiments have shown that the plants can uptake and even biotransform the ABZ, however, it is not known whether these phenomena occur in the real field conditions. The present study monitors the transfer of ABZ and its transformation products (TPs) from the faeces of treated sheep to common fodder plants such as Medicago sativa and Trifolium pratense. We wanted to know whether the possibility of transferring these compounds from excrement into the soil and from soil to plants exits in real field conditions. Our study successfully revealed the occurrence of ABZ TPs (ABZ-SO and ABZ-SO2) in both fodder plants. The highest...
