The environmental risks of pharmaceuticals have been studied less frequently in comparison to other chemicals such as pesticides and biocides. Nevertheless, during the last few years, veterinary and human medicinal products gained increasingly more attention. Medicinal products for use in veterinary medicine include various groups of chemicals, used for a wide range of purposes for companion and farm animals. The parasiticides and antibiotics are two of the most important groups and as such used fairly often in animal treatment. There are different entry routes of veterinary drugs into the environment. Manure of treated farm animals may contain significant amounts of the active ingredients or metabolites. They can be excreted from treated animals in agricultural soils directly (pasture) or with the application of manure as a fertiliser. The aquatic environment can also be one of exposure compartments. In this review we will focus on certain veterinary parasiticides and give a few examples how they can be excreted into environment and what is their environmental persistency and toxicity to some aquatic and terrestrial organisms.
