  • Veterinary medicines as an environmental problem = Problematika veterinarskih zdravil v okolju
    Kolar, Lucija, 1976-
    There are over 100.000 chemicals of different origin present in the environment in the 21. Century, among which30 % of them belongs to pharmaceuticals. Widespread concern about the environmental ... impacts of chemicals led to the development of a new scientific discipline - ecotoxicology. Veterinary medicines posed no threat until recently. As global livestock industry and also number of companion animals is (still) growing, the usage of mentioned substances is intensively expanding. Due to the increased use and their special chemical character, scientists and governmental institutions started with a more focused approach and in-depth studies regarding the problem. Avermectins are one of most frequently used veterinary medicines. After their use, they eliminate from the body in their active form, end up in the environment and as such interfere with a diverse range of biological systems. Indigenous sheep breed IstrianPramenka treated with therapeutic dosages were used in the study. Time profiles of excretion and concentration of avermectins in faeces were established, using a chemical procedure. Degradation of avermectins under different conditions was also followed. We performed also ecotoxicological studies looking at the effects onsoil dwelling organisms with a final conclusion in an environmental risk assessment scheme. Performed ecotoxicological study enables an in-depth view into the possible consequences of such large-scale pharmaceuticals use.
