Abstract
Organic arsenic, usually found in animal feed and livestock farm wastewater, is a carcinogenic and life-threatening substance. Hence, for the rapid and sensitive detection of organic arsenic, the development of new fluorescent sensors is quite essential. Here, an acid-base stable coordination polymer (HNU-62) was constructed by the introduction of hydrophobic fluorescence ligand, which can be used as a highly selective sensor for the detection of roxarsone (ROX) in water. The limit of detection (LOD) of HNU-62 for ROX was 4.5 × 10-6 M. Furthermore, HNU-62 also exhibits good anti-interference and recyclability, which can be used in detecting ROX in real samples of pig feed. This work provides an alternative approach for the construction of water-stable coordination polymer-based fluorescence sensors.

Abstract
Methyl parathion (MP) residues have aroused extensive attention on account of their significant threat to the environment and food safety. Currently reported fluorescent methods used for MP sensing largely depend upon an enzyme. Designing a facile and specific enzyme-free MP fluorescent sensor is in great demand, which remains a challenge. Here, negatively charged Cu nanoclusters (CuNCs) anchored on positively charged melamine-formaldehyde (MF) microspheres (MF@CuNCs) through an electrostatic interaction were prepared. MF microspheres triggered aggregation-induced emission (AIE) of CuNCs and successfully circumvented the shortcomings of poor stability and low luminescence of CuNCs. The fluorescence intensity of MF@CuNCs can be quenched by p-nitrophenol produced by MP under alkaline conditions. Accordingly, a specific enzyme-free MP sensing method was constructed with MF@CuNCs. In combination with a smartphone, visually quantitative analysis of MP in a fast and portable way was also achieved. For the first time, AIE of CuNCs used for enzyme-free MP sensing was successfully explored in this work, and it is believed that this method will open a new pathway for AIE of CuNCs to be applied in various applications.

A Highly Water-Soluble and Solid State Emissive 1,8-Naphthalimide as a Fluorescent PET Probe for Determination of pHs, Acid/Base Vapors, and Water Content in Organic Solvents. Molecules 2022; 27:molecules27134229.

Abstract
A new highly water-soluble 1,8-naphthalimide fluorophore designed on the “fluorophore-spacer-receptor1-receptor2” model has been synthesized. Due to the unusually high solubility in water, the novel compound proved to be a selective PET-based probe for the determination of pHs in aqueous solutions and rapid detection of water content in organic solvents. Based on the pH dependence of the probe and its high water solubility, the INH logic gate was achieved using NaOH and water as chemical inputs, where NaOH is the disabler and the water is an enabler. In addition, the probe showed effective fluorescence “off-on” reversibility on glass support after exposure to acid and base vapors, which defines it as a promising platform for rapid detection of acid/base vapors in the solid-state, thus extending the molecular sensing concept from solution to the solid support.

ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2022; 293:118550. [PMID: 34813886 DOI: 10.1016/j.envpol.2021.118550] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 11/11/2021] [Accepted: 11/17/2021] [Indexed: 06/13/2023]
Abstract
In this study, we backward traced and controlled the pollution of organophosphorus flame retardants (OPFRs) in aquaculture areas from the standpoints of terminal treatment, migration and transformation resistance, and source molecular substitution technology. A regulatory plan to considerably reduce the combined biotoxicity of fish exposed to OPFRs in aquaculture areas and significantly improves the biodegradation of sewage treatment and the efficiency of soil plant-microorganism combined remediation was formulated. Environmentally friendly alternatives of OPFRs were designed. The supplementation scheme of aquatic feed significantly alleviates the toxicity risk of fish exposure to OPFRs in aquafarm (reduced by 121.02%). The regulatory scheme of external stimulus to enhance the biodegradation of OPFRs in wastewater treatment process included an H2O2 concentration of 400 mg/L, voltage gradient of 1.5 V/m, and pH of 6.5 can improve the degradation capacity of OPFRs molecules by 88.86%. The degradation of OPFRs can be enhanced by plant-microorganism combined remediation (up to 98.64%) by growing plants whose primary function is phytoextraction in soils dominated by Sphingopyxis sp. and Rhodococcus sp. A 3D-QSAR pharmacophore model based on apoptosis toxicity, mitochondrial dysfunction, oxidative stress response, reproductive, neurotoxicity, gill-inhalation combined toxicity of fish exposed to OPFRs in aquafarm was fabricated. The recommended aquatic feed scheme and the control scheme of enhanced degradation of OPFRs by sewage treatment and soil environment had better applicability for the new-designed OPFRs substitution molecules (the maximum combined toxicity/degradation is reduced/increased by 75.46% and 63.24%, respectively). In this paper, a technical scheme of OPFRs terminal treatment, process regulation, and source control was applied as a cradle-to-grave approach to reduce the ecological toxicity risk of fish exposed to OPFRs in aquaculture areas providing theoretical support for the realization of OPFRs environmental pollution control.
