The current study was conducted to determine the potential
for some antibiotics to be taken up by food plants from soil fertilized with
manure, sewage sludge or its compost containing antibiotic residues. The
plants (potato – Solanum tuberosum L., carrot – Daucus carota L., and
wheat – Triticum aestivum L.) were cultivated in greenhouse under natural
light conditions in the presence of three fluoroquinolones (ciprofloxacin,
ofloxacin, and norfloxacin), and two sulfonamides (sulfadimethoxine and
sulfamethoxazole). The uptake of antibiotics was demonstrated from two
different soils (loamy and loamy sand). The concentrations of each
antibiotic in soil were 0.01, 0.1, 0.5, 1.0, and 10 mg kg–1. The antibiotics
were extracted from the plants using the liquid extraction (LE) and cleaned
up by the solid phase extraction (SPE). The extracts were analyzed by
liquid chromatography electrospray ionization tandem mass spectrometry
(LC-ESI-MS/MS). The accumulation range depended on antibiotic con-
centration in soil, chemical properties of the antibiotic, soil type, plant
species and parts (overground or below-ground). At soil concentrations of
10 mg kg–1 antibiotics accumulated in edible parts of most plants in
amounts, which exceeded their maximum residue levels (MRL) set for
food of animal origin – 100 μg kg–1. The highest average content of
antibiotics was detected in potato tubers and carrot roots grown in the
loamy sand soil – 3897 μg kg–1 and 3400 μg kg–1 sulfamethoxazole. Plants
accumulated antibiotics (ciprofloxacin and ofloxacin) from soil even at
soil concentration of 0.01 mg kg–1. Mostly the highest concentrations of
antibiotics were detected in below-ground parts of the plants grown in the
loamy-sand soil.
