“…The possible reason was because of the superior conductivity of P(L-Glu). 42,43 After further modification with SEB-β-CD, the value of the current response of OFL was further enlarged. It might be because the hydrophobic cavity of SEB-β-CD allows β-CD to form inclusion complexes with benzoxazin bases of OFL, which accelerates the absorption of OFL on the modified electrode.…”

The residue of ofloxacin (OFL) in animal-derived food would seriously affect human health. This study reports an inexpensive, fast, and simple electrochemical sensor for the sensitive detection of OFL in animal-derived food samples. A poly-L-glutamic acid/poly(sulfobutyl-β-cyclodextrin) CdTe quantum dot-modified electrode P(L-Glu)/SEB-β-CD@CdTeQDs/GCE was prepared by electrochemical polymerization reaction. We investigated the electrochemical behavior of OFL on the sensing electrode by cyclic voltammetry and square wave voltammetry. The results showed that the sensitivity of the sensor was significantly improved under the synergistic effect of L-glutamic acid, sulfobutyl-β-cyclodextrin, and CdTe quantum dot. In addition, the electrochemical reaction process of OFL on the sensing electrode was investigated and the results showed that the transfers of two protons and two electrons were involved in the reaction. Subsequently, the electrochemical sensing method based on P(L-Glu)/SEB-β-CD@CdTeQDs/GCE was developed and validated for the determination of OFL, showing a good linear response in the range of 0.07~1 μg·mL-1 with a detection limit of 3.4 ng·mL-1, and the precision and accuracy were high enough. Compared with the conventional HPLC method, the established electrochemical sensing method shows the merits of eco-friendly, shorter detection time, and much more simple, sensitive, and convenient.

“…According to a previous description, the pattern and manufacturing procedures of the SPGE were carried out on a PVC substrate utilizing in-house screen printing. 21 Briefly, graphene ink was screened to produce working and counter electrodes. Ag/AgCl ink was also screened on the same SPE to form a reference electrode and conductive pad.…”

“…The problem of air pollution with PAHs in Europe is well known (Schreiberová et al 2020 ), and it entails negative consequences for people exposed to their harmful effects (Thangphatthanarungruang et al 2023 ). Exposure of humans and animals to PAHs can lead to different effects depending on a diversity of coefficients (Sun et al 2021 ).…”

Classical monitoring of air pollution provides information on environmental quality but involves high costs. An alternative to this method is the use of bioindicators. The purpose of our work was to evaluate atmospheric aerosol pollution by selected polycyclic aromatic hydrocarbons conducted as part of annual active biomonitoring (“moss-bag” technique) with the use of three moss species: Pleurozium schreberi, Sphagnum fallax, and Dicranum polysetum. The gas chromatography-mass spectrometry (GC–MS) was utilized to determine certain 13 polycyclic aromatic hydrocarbons (PAHs). Three seasonal variations in PAH concentrations have been observed as a result of the study. A fire on the toilet paper plant caused an increase of five new compounds: benzo(k)fluoranthene (BkF), benzo(a)pyrene (BaP), indeno(1.2.3)-cd_pyrene (IP), dibenzo(a.h)anthracene (Dah), and benzo(g.h.i)perylene (Bghi) in proximity after 8 months of exposure compared to previous months. The effect of meteorological conditions on the deposition of PAHs (mainly wind direction) in mosses was confirmed by principal component analysis (PCA). Dicranum polysetum moss accumulated on average 26.5% more PAHs than the other species, which allows considering its broader use in active biomonitoring. The “moss-bag” technique demonstrates its feasibility in assessing the source of PAH air pollution in a long-term study. It is recommended to use this biological method as a valuable tool in air quality monitoring.
