“…Also, the intensity of fluorescence spectra was reduced and this effect was stronger in Cd than TC treatments. A similar shift of fluorescence spectra (5 nm) was observed with Chl from leaves of lupin growing in TC contaminated soil TC (Rydzyński et al 2017). The fluorescence spectra shifts confirm the formation of chlorophyll degradation product under the action of TC and Cd on plants.…”

“…SPE cartridges were rinsed with methanol and after loading with plant saps were eluted with 250 µl methanol. Tetracycline content in seedlings was analyzed by HPLC (Water Alliance 2695) according to Pailler et al (2009) with small modifications by Rydzyński et al (2017).…”

“…It has been repeatedly demonstrated that both antibiotics (Margas et al 2016;Zhao et al 2002;Rydzyński et al 2017) and cadmium (Küpper et al 2006) inhibit photosynthesis and contribute to the generation of reactive oxygen species (ROS) (Andresen and Küpper 2013). ROS cannot be formed directly in the Fenton or Haber-Weiss reaction (Wardman and Candeias 1996), but they may arise indirectly, due to the impairment of photosynthesis or respiration.…”

Degradation of chlorophyll was studied in leaves of spinach grown in soil containing cadmium and tetracycline, based on spectroscopic measurements and biochemical analyses of plant extracts. It was shown that plant exposure to the highest levels of tetracycline and cadmium resulted in 64% and 68%, respectively, reduction in chlorophyll content. The chlorophyll degradation rate constants were determined, and they were found to increase with increasing doses of tetracycline and cadmium. The rate constant of chlorophyll degradation by tetracycline ranged from k = 960 M −1 day −1 to k = 2180 M −1 day −1 , and the rate constant of chlorophyll degradation by cadmium ranged from k = 1130 M −1 day −1 to k = 2580 M −1 day −1 , depending on dose. Plant stress responses to tetracycline are much stronger than to cadmium, as is visible from the activity of guaiacol peroxidase and catalase. However, phytotoxicity of cadmium, measured by the rate of chlorophyll degradation and enzyme activities, is much higher compared to tetracycline. The spectroscopic measurements were taken 10 days after tetracycline and cadmium were added to the reagent grade chlorophyll which was used at the concentration of chlorophyll in plants. Changes in absorption and fluorescence spectra are likely to result from removal of magnesium from the chlorophyll molecule, and thus they indicate the formation of pheophytin. Cadmium, on the other hand, is probably bound into the chlorophyll molecule, substituting its magnesium.

“…Quinolones have been widely used because of their ease of absorption, high drug levels in blood and lower cost amongst other advantages. CIP, originally developed by Bayer AG, has the basic features of fluoroquinolones, namely a broad antifungal spectrum and sterilizing effects . As for antimicrobial activity, CIP ranks first among all fluoroquinolones used in clinical practice .…”

BACKGROUND Fluoroquinolone antibiotics and their metabolites can accumulate in soil and water. Trace amounts of fluoroquinolone antibiotic residues in the environment necessitate the pretreatment of samples prior to analysis. In this work, a polyoxyethylene cetyl ether (POELE20)–NaH2PO4 aqueous two‐phase system (ATPS) was combined with high‐performance liquid chromatography (HPLC) to separate and determine trace quantities of ciprofloxacin (CIP), norfloxacin (NRF) and pefloxacin (PEF) in environmental samples. RESULTS Single‐factor, multi‐factor, reproducibility and accuracy experiments were performed. The extraction efficiencies and enrichment factors for the three antibiotics were above 90 and 13.8%, respectively, under optimal conditions. The recovery efficiency of CIP was 92.08–99.50%, with a relative standard deviation (RSD) of 0.60–6.34%, and the recovery efficiency of NRF and PEF was 93.40–99.30%, with RSD of 0.98–5.16%, when this method was applied to spiked water and soil samples. The RSDs of intra‐ and inter‐day analyses were 1.56–3.42 and 1.33–3.97%, respectively. CONCLUSIONS This study demonstrated that POELE20–NaH2PO4 ATPS coupled with HPLC was suitable for the simultaneous separation, concentration and determination of trace quantities of CIP, NRF and PEF in environmental samples. Moreover, this method can be applied for the determination of trace fluoroquinolone antibiotics in food samples. © 2019 Society of Chemical Industry
