High through-put determination of 28 veterinary antibiotic residues in swine wastewater by one-step dispersive solid phase extraction sample cleanup coupled with ultra-performance liquid chromatography-tandem mass spectrometry

Development of a rapid pre-concentration protocol and a magnetic beads-based RNA extraction method for SARS-CoV-2 detection in raw municipal wastewater

“…In the experimental group that tested the clean-up of the 1-mL elute prior to RNA extraction using a dSPE salt mixture, only one of three replicates resulted in a positive detection for HI-SCV-2 RNA. Although dSPE (using PSA and C18) has been successful in the clean-up of complex wastewater matrices for the analysis of antibiotic residues 54 and illicit drugs, 55 PSA may have interfered with the HI-SCV-2 surrogate. For example, murine norovirus has been found to adhere to beads coated with PSA, and the degree of adhesion varied with pH.…”

Zebrafish as a Screening Model to Study the Single and Joint Effects of Antibiotics

“…Another study performed in Coimbra (Portugal) reported high concentrations of ofloxacin (0.3–10.6 μg/L) and ciprofloxacin (0.1–11 μg/L) in hospital effluents [ 49 ]. The concentration of enrofloxacin in the swine wastewater was up to 1.793 mg/L and levels of >0.1 mg/L were observed for sulfamonomethoxine, trimethoprim, ciprofloxacin, ofloxacin, lincomycin and tetracycline from certain pig farms [ 50 ]. The removal percentage of oxytetracycline in the wastewater treatment was 38 ± 10.5%, and the antibiotic concentration was still as high as 19.5 ± 2.9 mg/L in the treated outflow [ 51 ].…”

Trends in sensitive detection and rapid removal of sulfonamides: A review

“…First, modification of the cleanup step is essential for sulfonamide enrichment because sulfonamides exist in complex matrices, which may contain a high water content and impurities. Commonly used F I G U R E 7 Scheme of the main steps in the original QuEChERS process adsorbents in the cleanup process include primary secondary amine [93,94], C18 [95], graphitized carbon black [96], and their mixtures [97][98][99]. Newly synthesized adsorbents have also been developed to improve the cleanup efficiency, including graphene [57] and multiwalled carbon nanotubes (MWCNTs) [30].…”
