The use of high amounts of veterinary drugs is the primary source of residues of tetracycline and sulfonamide antibiotics in liquid manure, soil, and shallow groundwater. Another important finding from our work was that various antibiotics used as veterinary drugs can attach to dust particles and spread through the air of pig confinement buildings.
Abstract:
Newly developed mass-spectrometric techniques made it possible to detect tetracyclines on farmed land at concentrations of up to several hundred μg/kg soil, demonstrating that this group of antibiotics is persistent and may accumulate in soil after repeated fertilization with liquid manure from intensive pig farming. These field studies gave no proof of leaching of these compounds into deeper soil segments because of the strong sorption of the drugs in topsoil. However, in the fifth year of our field investigations we found that tetracycline had reached the groundwater. Investigations of the same fields showed that sulfamethazine occurred in significantly lower concentrations (a few μg/kg) in the plough layer. Although apparently present in soil at very low concentrations, sulfamethazine was detected repeatedly in groundwater samples. Furthermore, a new entrance route for veterinary drugs into the environment has been discovered: various antibiotics used as veterinary drugs can attach to dust particles in the mg/kg-range and spread through the air of pig confinement buildings. This retrospective study provides the first evidence of a heretofore unsuspected direct risk for human health arising from the inhalation of dust contaminated with a cocktail of antibiotics. Further investigations are urgently recommended to obtain deeper insights into the occurrence, fate and behaviour of veterinary drugs in the environment, as well as their possible effects e.g. on the structural and functional biodiversity of soil microorganism communities.
