Persistent organic pollutants (POPs) in fish species from different lakes of the lesser Himalayan region (LHR), Pakistan: The influence of proximal sources in distribution of POPs

Fish dwelling in remote mountain water systems are sensitive to long term exposure of POPs and can be used as an important bioindicator of POPs pollution in fragile mountain ecosystems. Current study aimed to investigate the concentrations and patterns of organic pollutants in fish tissues from different lakes of the Lesser Himalayan Region (LHR). OCPs, PCBs, PBDEs were analyzed in four common edible fish species of the LHR: Oncorhynchus mykiss, Labeo rohita, Hypophthalmichthys molitrix and Orechromis aureus. The fish were collected from lakes with different types of catchment areas (glacial, non-glacial mountain region and urban region) and extent of anthropogenic influence. The levels OCPs, PCBs and PBDEs analyzed in the selected fish species were in range of 0.21-587, 6.4-138 and 1.2-14 ng g(-1) lw, respectively. The SDDTs, higher chlorinated PCBs, tetra- and pentaBDEs were more prevalent in urban and remote lakes whereas pp’-DDE, lower chlorinated PCBs and BDE-47 and -99 were predominant in fish species from glacial lakes. SDDTs, SPCBs and SPBDEs showed statistically significant differences (p < 0.05) among species, trophic guilds (carnivore, herbivore and omnivore) and feeding regimes (surface, bottom and column feeder) and SHCH showed a significant difference only among trophic guilds. The stable isotope values of delta N-15 and delta C-13 differed significantly among species for SSHCH, SPCBs, SPBDEs (p < 0.05) and SDDT (p < 0.01). The range of delta C-13 values (-34 to-19%) indicated the importance of littoral and pelagic sources of dietary carbon. Trophic position and dietary proxieswere identified as important variables for explaining the variability of the studied compounds. Kohonen self-organizing maps (SOM) showed that in addition to trophic position and other physiological characteristics of fish, that the type of lakes and proximal sources of POPswere the most important predictors for distribution of organic contaminants in fish samples from LHR.

The effect of a polycarboxylate ether on C(3)A/CaSO4 center dot 2H(2)O passivation monitored by optical spectroscopy

Polycarboxylate ethers (PCEs) are widely used in construction, but the exact nature of their interaction with cement is still debated. Aiming at a better understanding of the role of tricalcium aluminate (C(3)A) in cement hydration, we assessed the potential of optical spectroscopy in combination with a water-soluble fluorescent organic reporter dye (S0586) to monitor the early hydration of C(3)A in the presence of 26 wt% CaSO4 center dot 2H(2)O (C(3)A26G-S) with and without PCE. As optical methods, steady-state fluorescence and diffuse reflectance (UV-VisDR) spectroscopy were employed. Phase characterization and particle size distribution were performed with in-situ X-ray diffraction (in-situ XRD) and dynamic light scattering (DLS). Our results show that fluorescence and UV-VisDR spectroscopy can be used to monitor the formation of metastable phases by the disaggregation of the dye 50586 in a cement paste as well as changes in ettringite formation. Addition of PCE slowed down the disaggregation of the dye as reflected by the corresponding changes of the dyes absorption and fluorescence. This prolonged induction period is a well-known side effect of PCEs and agrees with previous reported calorimetric studies and the inhibition of gypsum dissolution observed by in-situ XRD. This demonstrates that fluorescence and UV-VisDR spectroscopy together with a suitable optical probe can provide deeper insights into the influence of PCE on C(3)A-gypsum hydration which could be e.g., utilized as screening method for comparing the influences of different types of PCEs.

Effect of bamboo-like carbon nanotubes on morphology, electrical properties, and thermal conductivity of poly(ether-ketone) matrix nanocomposites

Bamboo-like carbon nanotube (CNT) reinforced poly(ether-ketone) (PEK) based nanocomposites were prepared via powder metallurgy route. The DC and AC electrical conductivities of the nanocomposites increased on increasing CNT loading in the PEK, marking an improvement of around 10 orders of magnitude for the 1.95 vol.% CNT reaching similar to 10(-3) S/cm and similar to 10(-4) S/cm (at nearly all the frequencies), respectively. The percolation threshold occurs between 1.3 vol.% and 1.95 vol.% CNT and the dielectric constant increased to similar to 60. The thermal stability and the thermal conductivity of the nanocomposites were increased. Semi-empirical Helpin-Tsai model correlated nicely with the thermal conductivity of the nanocomposites.

Influence of surfactants on a pre-adsorbed cationic layer: Removal and modification

Removal of organic species from solid surfaces is a crucial process. The use of oppositely charged surfactants provides a potential method for enhanced removal. Neutron reflectometry has been used to investigate the complex behaviour of a pre-adsorbed and tenacious layer of the cationic surfactant didodecyldimethylammonium bromide (DDAB) on a mica surface, during exposure to different organic species in solution. The anionic surfactant sodium dodecylsulfate (SDS) was shown to be able to remove the cationic layer, but only if anionic micelles were present in solution. To facilitate comparison with the behaviour of a non-ionic surfactant, the direct adsorption of pentaethylene glycol monododecyl ether (C12E5) to mica was also studied; low surface coverage adsorption was seen at the critical micelle concentration and above. C12E5 was then found not to remove the cationic layer, but did include into the layer to some degree. The presence of cationic surfactant on the mica was however shown to significantly modify the adsorption behaviour of the non-ionic surfactant. (C) 2020 Elsevier Inc. All rights reserved.

Application of chromatographic analysis for detecting components from polymeric can coatings and further determination in beverage samples

Major type of internal can coating used for food and beverages is made from epoxy resins, which contain among their components bisphenol A (BPA) or bisphenol A diglycidyl ether (BADGE). These components can be released and contaminate the food or beverage. There is no specific European legislation for coatings, but there is legislation on specific substances setting migration limits. Many investigations have paid attention to BPA due to its classification as endocrine disruptor, however, few studies are available concerning to other bisphenol analogues that have been used in the manufacture of these resins. To evaluate the presence of this family of compounds, ten cans of beverages were taken as study samples. Firstly, the type of coating was verified using an attenuated total reflectance-FTIR spectrometer to check the type of coating presents in most of the samples examined. A screening method was also performed to investigate potential volatiles from polymeric can coatings of beverages using Purge and Trap (P&T) technique coupled to gas chromatography with mass spectrometry detection (GC-MS). Moreover, a selective analytical method based on high performance liquid chromatography with fluorescence detection (HPLC-FLD) for the simultaneous identification and quantification of thirteen compounds including bisphenol analogues (BPA, BPB, BPC, BPE, BPF, BPG) and BADGEs (BADGE, BADGE center dot H2O, BADGE center dot 2H(2)O, BADGE center dot HCl, BADGE center dot 2HCl, BADGE center dot H2O center dot HCl, cyclo-di-BADGE) in the polymeric can coatings and in the beverage samples was applied. In addition, a liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) method was optimized for confirmation purposes. The method showed an adequate linearity (R-2 >0.9994) and low detection levels down to 5 mu g/L. Cyclodi-BADGE was detected in all extracts of polymeric coatings. The concentrations ranged from 0.004 to 0.60 mg/dm(2). No detectable amounts of bisphenol related compounds were found in any of the beverage samples at levels that may pose a risk to human health, suggesting a low intake of bisphenols from beverages.

Thermodynamics of acetaminophen and bovine serum albumin partitioning in ternary aqueous solutions comprising polyethylene glycol dimethyl ether 250 and choline bitartrate: Liquid-liquid equilibria, volumetric and acoustic investigations

The present work reports the biocompatible and nontoxic aqueous biphasic system, ABS, for acetaminophen and bovine serum albumin, BSA, separation. First, the binodal curves and tie-lines for {polyethylene glycol dimethyl ether 250 (PEGDME(250)) + choline bitartrate ([Ch][Bit]) + water} system was measured at different tempera- tures under atmospheric pressure (approximate to 85 kPa). The phase separation in this ABS was studied by the salting-out coefficents obtained from tie-lines correaltion with setschenow equation. The results indicated that the biphasic region was enhanced by enhancing tempera tre. The experimental data were fitted by two semi-empirical equations induding Marchuk and Zafarani-Moattar equations for binodals and Othmer-Tobias, Bancroft, Osmotic virial equations, and e-or m-NRTL models for the tie-lines. Later, the performance of this ABS in acetaminophen and BSA partitioning was examined via calculation of partition coefficients and extraction efficiencies at different tie-lines and temperatures, the trend showed that the acetaminophen could be partitioned preferentially into the polymer-rich top phase with a single step extraction efficiency up to 80%, in where the BSA was effectively transferred into the [Ch][Bit]-rich bottom phase. In order to evaluate the driving-force for acetaminophen preferentially transferring to top phase, density and sound speed for systems (acetaminophen + PEGDME(250) water) and (acetaminophen – [Ch][Bit] + water) were determined at 298.15 K and the obtained results utilized for calculation the infinite molar volume and compressibility, and the transfer molar volume and compressibility. From density and sound speed results, it may be concluded that the favorable interactions between acetaminophen and PEGDME(250) is responsible for preferentially acetaminophen transferring into top phase.

Typical organic pollutant-protein interactions studies through spectroscopy, molecular docking and crystallography: A review

With the development of industry and human society, more attention was paid for the toxic effects of organic pollutants that are closely related to human daily life. Previous studies mainly focused on the dose-response relationship and cytotoxic effects of pollutants to organisms, while little research focused on pollutant-protein interactions at molecular level. However, the binding of organic pollutants to biomolecules, especially proteins like transporters, membrane receptor and nuclear receptors, is often the first step of toxic effects. It can make a series of endocrine disrupting and genotoxic effects through cell signaling pathway by binding specific target proteins including scrum albumin, thyroid transporter, estrogen receptor, androgen receptor, and aryl hydrocarbon receptor. Thus, the research of interactions between organic pollutants and proteins is helpful and necessary to understand the distribution, metabolism and toxicity mechanism of compounds in organisms at the molecular level. This paper reviewed the latest research progress of the interaction types of persistent organic pollutants (POPS), emerging pollutants and some other pollutants with targeted proteins. In addition, we summarized several main experimental techniques for studying pollutant-protein interactions including ultraviolet;’visible absorption spectrometry (UV-vis), fluorescence, infrared spectrometry, circular clichroic spectra (CD), molecular docking and X-ray crystallography. This review contributes to the molecular mechanism of the interaction between organic pollutants and biomolecules. (C) 2020 Elsevier B.V. All rights reserved.
