Organophosphite antioxidants (OPAs) are important auxiliary used in plastic polymers and can be oxidized to organophosphate esters (OPEs) during production processing. In this work, the occurrence of OPAs OPEs farmlands with or without mulch film applications was investigated. Six five were detected, median concentrations 2.66 ng/g (∑6OPAs) 100 (∑5OPEs) film-mulching soil 1.16 47.9 nonfilm-mulching soil, respectively. The oxidative derivative AO168 (tris (2,4-di-tert-butylphenyl) phosphite),...
A novel method for highly selective recognition of UO22+ is proposed based on a [Eu(pyridine-2,5-dicarboxylic acid N-oxide)] (Eu-PDA) metal-organic framework. Benefiting from the unique chemical structure Eu-PDA, energy transfer PDA to was enabled, resulting in up-regulated fluorescence UO22+. The Eu-PDA probe showed excellent specificity over numerous interfering species, as intrinsic emissions were triggered.
Accurate determination of Ag+ released by silver nanoparticles (AgNPs) is vital for elucidating the environmental behaviors and defining exposure risks nanosilver. However, this remains challenging due to limitations in...
To reveal the metabolic characteristic of organophosphate esters (OPEs) in plants, uptake efficiency, subcellular distribution and hydrolysis OPEs their metabolites wheat (Triticum aestivum L.) were investigated by hydroponic experiments. Tris(2-chloroethyl) phosphate (TCEP) bis(2-chloroethyl) (BCEP) prone to transporting shoots transpiration stream, with translocation factors 6.2 21 for TCEP BCEP, respectively, as greater than 40% BECP distributed cell sap due hydrophilicity. Hydrophobic...
Bisphenol A (BPA) is an important endocrine disrupting chemical. Although high levels of BPA in some new clothes have been reported, the occurrence bisphenol chemicals including daily still unknown, and human exposure to has not well assessed. In this study, used/washed were collected from residents' wardrobes concentrations its analogues detected. was present all used at ranging <3.30 471 ng/g (median: 34.2 ng/g; mean ± SD: 57.5 93.6 ng/g), while S also detected 29% samples. higher average...
The quantitative detection methods for many microplastic (MP) polymers in the environment are inadequate. For example, effective nylon (polyamide, PA), a widely used plastic, different environmental samples still lacking. In present study, method based on acid depolymerization–liquid chromatography–tandem mass spectrometry (LC–MS/MS) and without separation of MPs from was developed to quantify MPs. After removing background monomer compounds, PA6 PA66 were efficiently depolymerized...
Organic phosphite antioxidants (OPAs) are widely added in plastic products and can be oxidized to generate derivatives (OPAs = O), namely organic phosphate esters (OPEs), during production use processing. Herein, the occurrence of OPEs OPAs five food packages was detected by liquid chromatography–tandem mass spectrometry. Three (TPhP, TCEP, AO168 O) three (TPhPi, TCEPi, AO168) were found packages, with concentrations <MQL-124 ng/g (∑3OPAs) 196–831 (∑3OPEs), respectively. The migration...
Uranyl ions (UO22+) are recognized as important indicators for monitoring sudden nuclear accidents. However, the interferences coexisting in complicated environmental matrices impart serious constraints on reliability of current on-site methods. Herein, a novel ratiometric method highly sensitive and selective detection UO22+ is reported based [Eu(diaminoterephthalic acid)] (Eu-DATP) metal–organic framework. Benefiting from unique chemical structure Eu-DATP, energy transfer DATP to was...
Performing fast and accurate analysis of perchlorate in the environment is crucial for environmental public safety. In this work, a novel strategy modifying 4,4′-(3′,4′,5′,6′-tetrakis(4-(pyridin-4-yl)phenyl)-[1,1′:2′,1″-terpheny]-4,4″-diyl)dipyridine (TPD) with varied alkyl chains to realize bright monomer excimer emissions simultaneously fine-tune their emission properties was proposed. The thoroughly characterized via regulating concentration luminophore length chain. It found that could...
