“…Grote et al (2006) observed in an experiment with winter wheat grown on soils fertilized with CTC-containing pig manure that CTCs and their degradation products were transferred from the soil into the plants where they were translocated into the grain. Greenhouse studies indicated that corn, lettuce and potato plants take up sulfamethazine with concentrations ranging from 0.1 to 1.2 mg kg −1 dry weight.…”

“…In several studies effects of antibiotics on plant growth and uptake into plant organs were demonstrated (Hembrock-Heger 2007;Boxall 2010;Grote et al 2006;Hamscher 2008;Jjemba 2002;Kumar et al 2005b;Migliore et al 1995).

“…Antibiotics show different transfer factors as well as variance in degradation but a transfer into the plant was determined for some of them (Grote et al 2006). Endangerment of humans via the food chain is thus possible (Kennedy et al 2000).…”

As well as fertilizer benefits, reutilization of phosphor (P) from secondary sources and recycling materials such as sewage sludge, farmyard manures, composts, biogas residues or meat and bone meal products on agricultural soils bears the great risk of contaminating farm sites with organic xenobiotics. Contamination of groundwater, surface and drinking water as well as of aquatic sediments and soils with pharmaceuticals has been reported (Hamscher et al.

“…Die in vivoBildung dieser Komponenten ist in der Nährlösung und/oder während der Probenvorbereitung und Nachweisgrenze (TC). Daher kann davon ausgegangen werden, dass die in den einzelnen Pflanzenabschnitten neben den zudotierten Wirkstoffen nachgewiesenen zusätzlichen Komponenten überwiegend in vitro, also nach der Aufnahme über die Wurzel in den Pflanzen gebildet worden sind (Grote et al 2006;Freitag et al 2008).…”

Investigation on the transfer of pharmacologically active substances used in animal husbandry into leek and cabbage. The potential of leek and cabbage for uptake of highly prescribed veterinary drugs (antibiotics) was tested in hydroponically grown plants. For this purpose the antibiotics sulfadiazine (SFD), enrofloxacine (ENR), tetracycline (TC), chlortetracycline (CTC) and monensine (MON) were chosen. A further aim was to gain data on the situation of vegetables grown in agricultural practise with regard to antibiotic residues. The evident effects of the antibiotics on plants grown hydroponically (each antibiotic was administered at 5 lmol/l nutrient solution) were greatly different: With regard to leek there were no visible effects (MON, SFD), a weak bleaching of the younger leaf sections (CTC), and strong effects of ENR. The (phytotoxic) effects of antibiotics on cabbage were much more distinct. CTC caused a yellowing of the plant vasculature in cabbage. MON induced lesions on some leaves and finally led to leaf wilting. With administration of ENR a nearly complete bleaching of young leaves was observed. Using LC-MS/MSmethods (low-resolution and high-resolution MS) the administered antibiotics, as well as conversion products and metabolites, were separately identified and quantified in various organs of leek (roots, young and old sections of leaves) and cabbage (roots, stalks, young and old leaves). Depending on the type of antibiotic, vegetable species, and plant organ, the detected concentrations of antibiotic residues comprised several orders of magnitude ranging from lg/kg to mg/kg of fresh weight (fw). The highest concentrations of antibiotics were found in roots of both vegetable species: CTC and TC were detected at approximately 10 mg/kg fw in cabbage roots and at approximately 20 mg/kg fw in leek roots and ENR was determined at approximately 12 mg/kg fw in cabbage roots. Low amounts of ENR were metabolised to ciprofloxacine (CIP). ENR occurred at similar concentrations of approximately 7 mg/kg fw in roots and old leaves of cabbage, indicating a high transport rate of this antibiotic in the cabbage plant. In stalks, young and old leaves of cabbage and in young and old leaf sections of leek all administered antibiotics were detected. Within these antibiotics, ENR and CTC and their conversion products, e. g. demeclocycline (DMC) and TC, occurred at the highest concentrations. SFD and MON were found in considerably lower concentrations (\100 lg/kg fw). The results of our experiments in hydroponic cultures, using defined concentrations of antibiotics in the nutrient solution, evidently demonstrate that

So liegen wissenschaftlich belegte Hinweise dafür vor, dass Tieren verabreichte Antibiotika über die auf Äckern ausgebrachte Gülle in den dort angebauten und geernteten Kulturpflanzen in nachweisbaren Konzentrationen auftauchen (Grote et al 2006(Grote et al und 2009 und dass das allgemein verfügbare Trinkwasser in einem gewissen Maße mit (Rückständen von) verabreichten Arzneimitteln aus der Humanmedizin belastet sind bzw. sein können (Kulaksiz und Bau 2009).…”
