[Less] A series of dyes; three symmetric free meso-tetraphenylporphyrins, bearing phenylacetylide (H2-TPA), . . . [More] A series of dyes; three symmetric free meso-tetraphenylporphyrins, bearing phenylacetylide (H2-TPA), hexyloxy (H2-OHex) or without peripheral substituent (H2-TPP) were chosen as luminophore to explore the effect of meso-substitution on the oxygen sensing ability. These dyes were incorporated into poly(trimethylsilylpropyne) [poly(TMSP)], polymethylmethacrylate (PMMA) and silicone matrices along with additives such as perfluorododecanoic acid (PFC) to improve the oxygen sensitivity as well as ionic liquid to favor the microfiber preparation by electrospinning. The pH of the medium is affected by the composition of the cocktail, a non-trivial effect which induce protonation of the free meso-tetraphenylporphyrin derivatives bearing electron donor (H2-OHex) and withdrawing substituents (H2-TPA), which results in absorbance and emission spectroscopic modifications called elsewhere hyperporphyrin effect. Spectrophotometric titrations were carried out by using HClO4 in THE solution and PFC in [poly(TMSP)]-based thin film to study the hyperporphyrin effect of H2-TPA, H2-OHex and H2-TPP showing the influence of the substituent bn the pKa of the inner nitrogen's. The ratio of PFC/dyes optimization was prospected and the influence of the pH/protonation on the steady-state oxygen sensitivity was studied. (C) 2017 Elsevier Ltd. All rights reserved.

The measurement of bisphenol A and its analogues, perfluorinated compounds in twenty species of freshwater and marine fishes, a time-trend comparison and human health based assessment

[More] Our previous study in 2011 reported the detection of BPA and PFAAs in 20 species of marine and freshwater fishes. With an emerging evidence to suggest the metabolic-disrupting effects of BPA/PFAAs in animals, the present study was aimed to provide a time-trend analysis to determine the current concentrations of PFAAs and BPA in 20 commercially available Hong Kong species of fishes. Since the manufacture and use of BPA is being prohibited in most nations, the introduction of BPA alternatives has recently been incorporated in the markets. Therefore, the concentrations of BPB, BPF and BPS were determined. In the present study, all freshwater and seawater fish samples showed quantified concentrations [>Limit of Quantification (LOQ<0.5ng/g)] of BPA. BPF was detected in some marine (yellow seafin, bigeye, goldspotted rabbitfish, snubnose pompano, tongue sole, Bleeker's grouper and orange-spotted grouper) and freshwater fishes (mud carp, crucian carp, tilapia, catfish, mandarin fish, grass carp, grey mullet and spotted snakehead). Two of the compounds, BPS and BPB could only be identified in the marine fishes (snubnose pompano, yellow seafin). In PFAA analysis, PFOA, PFDA, PFOS, PFUdA and PFDoA were found in most of the marine and freshwater fishes. PFOS and PFOA were shown to be the two predominant PFAAs in fishes. On the basis of the measured concentrations of bisphenols, BPs (BPA, BPB, BPF, BPS) and PFAAs, the average daily intake for BPs (20.5-31.5ng/kgb.w./day) and PFAAs (1.17-1.83ng/kgb.w./day) were calculated and found to be lower than values of tolerable daily intake (TDI) established in Europe. However, as compared with our previous study in 2011, the present study revealed an approximate 10-fold increase in the concentrations of BPA in the fish samples. Although the hazard ratio of consuming fishes for BPA and PFAA exposure is expected to remain low, possible additive metabolic-disrupting effect of BPA and its analogues as well PFAAs should be taken into consideration for human health risk assessment.

Perfluorododecanoic acid induces cognitive deficit in adult rats

[Less] The brain level of perfluorododecanoic acid (PFDoA) was compared with those of perfluorooctanoic acid . . . [More] The brain level of perfluorododecanoic acid (PFDoA) was compared with those of perfluorooctanoic acid (PFOA) and perfluorodecanoic acid (PFDA) in rats 9 days after a single oral dose (50 mg/kg). The PFDoA level in the brain was 44.0 ± 2.0 µg/g, which was higher than that in the serum (24.4 ± 1.0 µg/ml). In contrast, the concentrations of PFOA and PFDA in the brain were low (<0.8 and 4.7 ± 0.4 µg/g, respectively), and less than one-tenth of those in the serum. Next, to investigate the effects on brain function, the cognitive function alterations of PFOA, PFDA, and PFDoA were estimated by the novel object recognition test 5-6 days after dosing. A significant decrease in the discrimination index was observed in PFDoA-treated rats while no significant alteration was observed in PFDA- and PFOA-treated rats. The effects of PFDoA were further assessed by other behavioral tests. PFDoA-associated alteration was observed in the elevated-plus maze test, but not in the Y-maze test, open-field test, and forced swim test. A decrease in the discrimination index of the novel object recognition test was dependent on the PFDoA dose and the PFDoA concentration in the brain. PFDoA concentration in the brain was 28.6 ± 2.6 µg/g 30 days after dosing, and a decrease in discrimination index was observed. Taken together, these results suggest that PFDoA distributes in the brain easier than PFOA and PFDA and causes cognitive deficit.

Characterization of occurrence, sources and sinks of perfluoroalkyl and polyfluoroalkyl substances (PFASs) in a tropical urban catchment

[Less] Understanding the sources, occurrence and sinks of perfluoroalkyl and polyfluoroalkyl substances (PFASs) . . . [More] Understanding the sources, occurrence and sinks of perfluoroalkyl and polyfluoroalkyl substances (PFASs) in the urban water cycle is important to protect and utilize local water resources. Concentrations of 22 target PFASs and general water quality parameters were determined monthly for a year in filtered water samples from five tributaries and three sampling stations of an urban water body. Of the 22 target PFASs, 17 PFASs were detected with a frequency >93% including PFCAs: C4-C12 perfluoroalkyl carboxylates, C4, C6, C8, and C10 perfluoroalkane sulfonates, perfluorooctane sulfonamides and perfluorooctane sulfonamide substances (FOSAMs), C10 perfluoroalkyl phosphonic acid (C10 PFPA), 6:2 fluorotelomer sulfonic acid (6:2 FTSA) and C8/C8 perfluoroalkyl phosphinic acid (C8/C8-PFPIA). The most abundant PFASs in water were PFBS (1.4-55 ng/L), PFBA (1.0-23 ng/L), PFOS (1.5-24 ng/L) and PFOA (2.0-21 ng/L). In the tributaries, PFNA concentrations ranged from 1.2 to 87.1 ng/L except in the May 2013 samples of two tributaries, which reached 520 and 260 ng/L. Total PFAS concentrations in the sediment samples ranged from 1.6 to 15 ng/g d.w. with EtFOSAA, PFDoA, PFOS and PFDA being the dominant species. Based on water and sediment data, two types of sources were inferred: one-time or intermittent point sources and continuous non-point sources. FOSAMs and PFOS released continually from non-point sources, C8/C8 PFPIA, PFDoA and PFUnA was released from point sources. The highly water soluble short-chain PFASs including PFBA, PFPeA and PFBS remained predominantly in the water column. The factors governing solution phase concentrations appear to be compound hydrophobicity and sorption to suspended particles. Correlation of the dissolved phase concentrations with precipitation data suggested stormwater was a significant source of PFBA, PFBS, PFUnA and PFDoA. Negative correlations with precipitation indicated sources feeding FOSAA and FOSA directly into the tributaries.
