Toxicity warning and online monitoring of disinfection by-products in water by electroautotrophic biocathode sensors

Effects of long-term and incremental exposure to toxic pollutants on the current generation and microbial communities of electrochemically active bacteria

“…For instance, a 30 minute exposure to 1.5 mg L −1 Hg[ ii ] inhibited the voltage output of EAB in a sequentially flowing membrane-less MFC by 36%, while a 0.3 hour exposure to 0.25 mg L −1 CH 2 Cl 2 decreased the current consumption of a vertical penetrating flow three-electrode system by ∼10%. 20 Our results further confirm the acute toxicity of these pollutants during the early stage of toxic exposure. However, the long-term effects of toxic exposure on EAB current generation still need to be investigated.…”

“…A previous study reported that short-term exposure to CH 2 Cl 2 immediately decreased EAB viability and MFC voltage. 20 Our results provide further confirmation of the acute toxicity of CH 2 Cl 2 to EAB. However, we observed a decline in the inhibition effects as CH 2 Cl 2 concentrations increase.…”

Pathomorphological changes in laboratory animals exposed to lethal doses of disinfec-tants

“…Based on the presented data analysis, it can be inferred that the death of animals in our experiments was caused by the toxic effects of aldehydes. An innovative approach in modern toxicology involves the use of biocathode sensors due to their unique function of electroauto-trophic respiration (Liao et al, 2023). Regardless of the properties of any antimicrobial compounds, it is important to exercise caution when using antimicrobial compounds, taking into account their efficacy and safety based on evidence (Ambrosino et al, 2022).…”

“…Various methods and biological objects are used to assess the toxicity of drugs (Laingam et al, 2012;Ren et al, 2022;Seo et al, 2022). However, the most informative and closest to the practical conditions of using chemical compounds is the use of laboratory animals (Marxfeld et al, 2019;Jantawong et al, 2021;Lieshchova & Brygadyrenko, 2022). Mice are reported to be more sensitive than rats to acute oral toxicity (Ballantyne & Myers, 2001).…”

Compact In Situ Electrochemical NMR with Wireless and Anti-interference Strategy in Multiscenario Applications

“…In response, scientists have turned to spectroelectrochemistry, a discipline offering valuable insights into the molecular properties and behaviors of electroactive species. 7,8 Remarkably, the combination of electrochemistry with mass spectrometry enables the assessment of drug oxidative behaviors and the prediction of several drug metabolism features. 9−11 While mass spectrometry and spectrophotometric techniques have their challenges (e.g., mass spectrometry encounters varying ionization rates and often requires the use of trapping agents, and spectrophotometric methods can be influenced by the color and turbidity of a sample), nuclear magnetic resonance (NMR) offers distinct advantages.…”
