INSPIRED by the insight from American political scientist Lasswell, who summarized the environmental role in societal surveillance [1], Schramm coined the term “social radar” [2] as it resembles the activities of radar in collecting and processing information, playing a crucial role in helping humans perceive changes in the internal and external environment and promptly adjusting adaptive behaviors.

According to the historical records of Records of the Grand Historian (史记)and genomic evidence, the Han Chinese could trace their ancestry back to the Huaxia tribe, people who lived along the Yellow River basin since Neolithic times [1]. From this region, Han culture spread west into the Tibetan Plateau and south into southwest China over the past two millennia.

The degradation kinetics, reaction pathways, and disinfection by-products formation of an organic UV filter, benzophenone-4 (BP4) during UV/persulfate oxidation were investigated. BP4 can hardly be degraded by UV alone, but can be effectively decomposed by UV/persulfate following pseudo-first order kinetics. BP4 degradation rate was enhanced with increasing persulfate dosage and decreasing pH from 8 to 5. However, the degradation rate of BP4 at pH 9 was higher than that at pH 8 because of the presence of phenolic group in BP4 structure. and (Formula presented.) were confirmed as the major contributors to BP4 decomposition in radical scavenging experiments, and the second-order rate constants between (Formula presented.) and BP4 as well as those between (Formula presented.) and BP4 were estimated by establishing and solving a kinetic model. The presence of (Formula presented.) and humic acid inhibited the decomposition of BP4, while (Formula presented.) promoted it. The mineralisation of BP4 was only 9.1% at the persulfate concentration of 50 μM. Six degradation intermediates were identified for the promulgation of the reaction pathways of BP4 during UV/persulfate oxidation were proposed as a result. In addition, the formation of DBP in the sequential chlorination was evaluated at different persulfate dosages, pH values, and water matrix. The results of this study can provide essential knowledge for the effective control of DBP formation with reducing potential hazard to provide safe drinking water to the public. © 2023 Informa UK Limited, trading as Taylor & Francis Group.

Nowadays, it is necessary to explore efficient antibacterial materials to complement or substitute the conventional antibiotic, to cope with the ever-growing bacterial contamination. Here, a series of Cu-doped ZIF-8 materials are prepared and adopted for disinfection against typical bacteria E. coli and S. aureus in dark. The results show that 5-7 log efficiency can be achieved at a dosage of 15-30 mg mL-1 of 1.35 atomic % Cu doped ZIF-8, and this concentration is also safe as verified by cytotoxicity test. Mechanism investigation shows that Cu(II) is reduced to Cu(I), which would contribute to the effective electron transfer for the reactive oxygen species generation. And these reactive oxygen species would cause oxidative stress and membrane damage on bacteria cells. All these results show the promise of Cu-doped ZIF-8 in the antibacterial applications especially in the environments without any energy input. © 2024 18th Conference of the International Society of Indoor Air Quality and Climate, INDOOR AIR 2024 - Conference Program and Proceedings.
