“…This challenge calls for stringent mitigation plans to ensure the sustainability of groundwater-dependent species before they are extinct. Because implementation of even relatively simple mitigation strategies can be expensive, and even contentious, methods to evaluate their effectiveness should be included in the process 14 . We surveyed 710 aquifers globally that are home to 1,058 endangered and 651 threatened groundwater-bound species.…”

Overexploitation of groundwater threatens groundwater-bound aquatic and terrestrial biodiversity and ecosystem stability, underscoring the need to devise appropriate mitigation strategies. Yet, there is no hindsight evidence that mitigation measures effectively protect groundwater-dependent habitats. We provide unique and compelling evidence, using artificial intelligence and ground truth data, that mitigation measures can successfully sustain ecologically sensitive spring flows and ensure the sustainability of groundwater-bound threatened and endangered endemic species.

“…Antibiotics are significant drugs for treating bacterial infections and are widely applied in medicine, animal husbandry, and agriculture. − Ciprofloxacin (CIP) and norfloxacin (NOR), the third-generation synthetic quinolone antibiotics, have been extensively prescribed for several different types of human infections due to their high potency, favorable bioavailability, the broad spectrum of activity, high serum concentrations, oral and intravenous formulations, and relatively low incidence of side effects. − Nevertheless, alarmingly increased use of CIP and NOR has led to high levels of antibiotic residues, which pose a serious threat to environmental safety and human health. , The overdose and incomplete metabolization of CIP and NOR make them easy to accumulate in the body, causing serious damage to humans, such as hepatotoxicity, hematuria, and cholestatic jaundice. − Numerous methods have been explored so far for the detection of antibiotics, such as spectrophotometry, liquid chromatography-mass spectrometry, capillary electrophoresis, and high-performance liquid chromatography. − However, the complicated operation, time-consuming nature, and high cost of these methods limit their practical application. − Owing to its advantages of high sensitivity, economic feasibility, and easy operation, fluorescence detection has received extensive attention in modern chemical analysis, which is considered a promising candidate for the sensitive detection of antibiotic residues. ,, Consequently, it is significant to develop excellent fluorescence probes with ultra-low detection limits to detect the presence of CIP and NOR in human urine.…”

In recent years, alarmingly increased use of quinolone antibiotics has led to a large number of antibiotic residues in the bodies of organisms and threatened their health. It is crucial to develop efficient and sensitive methods for detecting quinolone antibiotics. For the europium (Eu(III)) complex, its characteristic emission is affected by the energy transfer from the excited singlet state and triplet states of the ligands to the emission energy level of the Eu(III) ion. If external stimuli could change its coordination environment or the stacking pattern, the intensity of the characteristic Eu(III) emission would be affected. Considering the abundant potential coordination sites of ciprofloxacin (CIP) and norfloxacin (NOR), we designed and prepared two europium complexes based on hydrazone, [Eu2L1 2(phen)2(NO3)2] (L1 = (E)-N′-(2-hydroxybenzylidene)nicotinohydrazide; phen = 1,10-phenanthroline) (Eu-1) and [Eu2L2 2(CH3OH)2(NO3)2] (L2 = (E)-N′-(2-hydroxybenzylidene)picolinohydrazide) (Eu-2). As expected, Eu-1 and Eu-2 showed a sensitive response to quinolone antibiotics (CIP and NOR). Upon the addition of CIP and NOR to the solutions of Eu-1 and Eu-2, the evident fluorescence enhancement corresponding to both the ligand and characteristic Eu(III) emission is clearly observed. The limits of detection (LODs) of Eu-1 for CIP and NOR are calculated to be 6.25 × 10–9 and 1.44 × 10–8 M, respectively, and those of Eu-2 for CIP and NOR are determined to be 2.86 × 10–8 and 4.22 × 10–8 M, respectively. The LODs and high values of K sv prove their excellent sensing performance. The high sensitivities and anti-interference abilities make Eu-1 and Eu-2 promising turn-on fluorescence probes for detecting CIP and NOR in human urine, based on which Eu-1 and Eu-2 have been successfully employed to developed paper strips for the on-site detection of CIP and NOR. In addition, Eu-1 and Eu-2 both exhibit high-contrast mechanochromic luminescence, which is attributed to the phase transformation from a crystalline to the amorphous state.
