Sulfadiazine Uptake and Effects on Salix fragilis L. and Zea mays L. Plants

Concomitant uptake of antimicrobials and Salmonella in soil and into lettuce following wastewater irrigation

“…The maximum concentration of antimicrobials in soil in this study (0.75-0.76 mg/kg) were higher than those found in studies where contaminated manure was incorporated into soil (Grote et al, 2007) were maximum detected soil concentrations of sulfonamides (sulfadiazine) and tetracyclines (chlortetracycline) at plant harvest were 0.090 mg/kg and 0.120 mg/kg, respectively. Other studies investigated uptake from soil spiked with antimicrobials and soil concentrations of 0.12-0.34 mg/kg were reported for a sulfonamide (sulfadiazine) with similar total antimicrobial exposure (Michelini et al, 2012). In Michelini et al (2012), soil was amended with 0, 10, and 200 mg/kg of antimicrobials, simulating loading typical of manure application.…”

The difference in antimicrobial accumulation in soils between this study and the present study may result from the high percentage of organic material in the soil mix used in our experiment.…”

Antibiotic‐induced effects on scaling relationships and on plant element contents in herbs and grasses

“…(2010) detected toxic effects of sulfadimethoxine on roots, cotyledons, and cotyledons petioles for all applied concentrations, while internodes and leaf lengths showed dose‐dependent responses. Other root‐related effects reported for antibiotics were decreased root length, root elongation, and numbers of lateral roots, indicating possible consequences for plant water uptake (Michelini et al., 2012; Piotrowicz‐Cieslak, Adomas, Nalecz‐Jawecki, & Michalczyk, 2010). …”

“…It is notable that the effects of antibiotics on element contents of plants have received much less attention. To our knowledge, only one study has hitherto investigated effects of sulfadiazine on the C:N and K:Ca ratios of willow and maize plants, and found significantly lower C:N and K:Ca ratios in high antibiotic treatments (Michelini, Reichel, Werner, Ghisi, & Thiele‐Bruhn, 2012). However, this study used concentrations (200 μg/g soil) that are much higher than typically found in agricultural soils (0.006–500 μg/kg soil, Thiele‐Bruhn, 2003).…”

Agronomic and environmental effects of land application of residues in short-rotation tree plantations: A literature review

“…The antibiotic, mainly accumulated in the roots, caused an alteration of root geotropism, an increased number of lateral roots, and a decrease of the water absorption. High doses caused a reduction in leaf C/N and chlorophyll contents [85]. Trimethoprim was toxic for the willows at a concentration of 100 g m À3 [86].…”
