The constant potential and current discharge techniques were used to determine the hydrogen diffusion coefficients in an electrode. values obtained , respectively. advantages disadvantages of these two are discussed.
This is the first study in last 15 years to analyze per- and polyfluoroalkyl substances (PFAS) breast milk collected from mothers (n = 50) United States, our findings indicate that both legacy current-use PFAS now contaminate milk, exposing nursing infants. Breast was analyzed for 39 PFAS, including 9 short-chain 30 long-chain compounds, 16 of these were detected 4-100% samples. The ∑PFAS concentration ranged 52.0 1850 pg/mL with a median 121 pg/mL. Perfluorooctanesulfonic acid (PFOS)...
Quaternary ammonium compounds (QACs or "quats") make up a class of chemicals used as disinfectants in cleaning and other consumer products. While disinfection is recommended for maintaining safe environment during the COVID-19 pandemic, increased use QACs concerning exposure to these has been associated with adverse effects on reproductive respiratory systems. We have determined occurrence 19 residential dust collected before pandemic. were detected >90% samples pandemic at concentrations...
Per- and polyfluoroalkyl substances (PFAS) make up a large group of fluorinated organic compounds extensively used in consumer products industrial applications. Perfluorooctanesulfonic acid (PFOS) perfluorooctanoic (PFOA), the two perfluoroalkyl acids (PFAAs) with 8 carbons their structure, have been phased out on global scale because high environmental persistence toxicity. As result, shorter-chain PFAAs less than structure are being as replacements now widely detected environment, raising...
Significance Organisms are exposed to a wide range of xenobiotics in the environment. Generally, metabolism individual water-soluble compounds is primary defense against these compounds. In this study, we discovered that phenolic undergo metabolic pathway form lipophilic ester compounds, and occurred within among different organisms. The provided mechanism for cross-talk reactions pollutants groups unknown during processes
Despite the increasing use and discharge of novel brominated flame retardants, little information is available about their trophodynamics in aquatic food web, subsequent relationships to compound metabolism. In this study, concentrations 2,4,6-tribromophenyl allyl ether (ATE), 1,2-dibromo-4-(1,2-dibromoethyl)cyclohexane (TBECH), tetrabromo-o-chlorotoluene (TBCT), pentabromobenzyl acrylate (PBBA), 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), bis(2-ethylhexyl)-3,4,5,6-tetrabromo-phthalate...
Quaternary ammonium compounds (QACs) are commonly used in a variety of consumer, pharmaceutical, and medical products. In this study, bioaccumulation potentials 18 QACs with alkyl chain lengths C8–C18 were determined the vitro–in vivo extrapolation (IVIVE) model using results human hepatic metabolism serum protein binding experiments. The slowest clearance rates estimated for C12-QACs, suggesting that these may preferentially build up blood. was further confirmed by analysis blood (sera)...
Despite their ubiquitous use, information regarding the presence of quaternary ammonium compounds (QACs) in various microenvironments remains scarce and only a small subset QACs has been monitored using targeted chemical analysis. In this study, total 111 dust samples were collected from homes public settings South China during COVID-19 pandemic analyzed for traditional emerging high-resolution mass spectrometry. The QAC concentrations residential (∑traditional QAC, sum 18 QACs) ranged 13.8...
Perfluorohexanesulfonic acid (PFHxS), an emerging short-chain per- and polyfluoroalkyl substance, has been frequently detected in aquatic environments. Adverse outcome pathway studies have shown that perfluorinated compounds impair lipid homeostasis through peroxisome proliferator activated receptors (PPARs). However, many of these were performed at high concentrations may thus be a result overt toxicity. To better characterize the molecular key events PFHxS to biota, early life-stage...
Naphthenic acids (NAs) are one class of compounds in wastewaters from petroleum industries that known to cause toxic effects, and their removal oilfield wastewater is an important challenge for remediation large volumes petrochemical effluents. The present study investigated occurrences behaviors total NAs aromatic a refinery treatment plant, located north China, which combined physicochemical biological processes. Concentrations were semiquantified be 113–392 μg/L all the units, percentages...
Organophosphate esters (OPEs) are among the synthetic chemicals found in highest concentrations indoor environment due to their use as flame retardants and plasticizers. In fish wildlife, metabolites of OPEs have been build up tissues. this study, 28 triester (tri-OPEs) seven corresponding diester (di-OPE) three hydroxyl were measured breast milk collected from 50 U.S. mothers. Tris(1-chloro-2-propyl) phosphate, used foam for insulation furniture target compound with largest production...
The widespread contamination of perfluorooctanesulfonate (PFOS) has raised global concerns due to its adverse effects on human health. Consequently, there is an urgent need for sensitive, reliable, and cost-effective techniques the in-field detection PFOS in environmental matrices. Herein, we present a portable electrochemical sensor analysis, utilizing screen-printed electrode (SPE) modified with molecularly imprinted polymer (MIP). MIP layer specifically recognizes electrochemically...
Per- and polyfluoroalkyl substances (PFAS) melamine (MEL)-based compounds are used in textile finishing as grease, stain, water repellents. Here, we investigated the occurrence of a large suite PFAS MEL 86 infant clothing items. The ∑MEL concentrations ranged from below method detection limit to 250,000 ng/g with median concentration 78.2 ng/g, significantly higher (p < 0.05) than ∑PFAS levels (1.22-203 ng/g; 3.62 ng/g). its derivatives were most abundant nylon clothes (median 32,800 ng/g),...
Electrochemical properties of bare and copper‐coated electrodes were investigated in alkaline solution. The exchange current density, polarization resistance, equilibrium potential determined as functions the state charge electrodes. symmetry factors for estimated to be 0.53 0.52, respectively. By using a constant discharge technique, hydrogen diffusion coefficient coated was .
The use of trophic magnification factors (TMFs) to characterize the bioaccumulation potentials chemicals was encouraged; however, method for assessment is still lacking. We optimized in vitro assays used measurement intrinsic clearance liver microsomes by incorporating benzo[a]pyrene (B(a)P) as a benchmark compound. 40 compounds then measured from fish (weevers) and birds (quail); characteristics transfer these were previously investigated an aquatic food web Bohai northern China.
