Anura; Cyanobacteria; algae; aquatic ecosystems; bacteria; biodiversity; ciprofloxacin; difloxacin; enrofloxacin; farms; fish; fluorescence; high performance liquid chromatography; humans; mass spectrometry; ofloxacin; risk; rivers; surface water; ultra-performance liquid chromatography; wastewater; water pollution; Argentina
Abstract:
... The use of fluoroquinolones for the treatment of infections in humans and animals has increased in Argentina, and they can be found in large amounts in water bodies. The present study investigated the occurrence and associated ecological risk of 5 fluoroquinolones in rivers and farm wastewaters of San Luis, Santa Fe, Córdoba, Entre Ríos, and Buenos Aires provinces of Argentina by high‐performance ...

Subject:
chemometrics; corn; detection limit; fluorescence emission spectroscopy; information processing; luminescence; pirimiphos-methyl; solid phase extraction; solvents
Abstract:
... A novel method for the determination of pirimiphos-methyl (PMM) in maize grains by fluorescence spectroscopy and three-way calibration was developed. The formation of supramolecular complexes and their effect on the luminescence properties of PMM were studied. A solvent extraction step followed by solid phase extraction for sample clean-up was optimized. A chemometric approach consisting in PARAFA ...

Subject:
acetonitrile; air; albendazole; chemometrics; chloramphenicol; eggs; enrofloxacin; liquid chromatography; liquid-phase microextraction; methanol; methylene chloride; nicarbazin; pH; sodium phosphate; solidification; solvents; trimethoprim; veterinary drugs; zinc sulfate
Abstract:
... Two extraction strategies for albendazole, chloramphenicol, trimethoprim, enrofloxacin, oxitetracycline and nicarbazin in egg were optimized for its quantitation by liquid chromatography. First, two designs were built to find out the optimized condition for the air assisted-dispersive liquid-liquid microextraction based on solidification of organic drop: a fractional factorial and a central compos ...
