TPhP exposure disturbs carbohydrate metabolism, lipid metabolism, and the DNA damage repair system in zebrafish liver

Abstract: Triphenyl phosphate is a high production volume organophosphate flame retardant that has been detected in multiple environmental media at increasing concentrations. The environmental and health risks of triphenyl phosphate have drawn attention because of the multiplex toxicity of this chemical compound. However, few studies have paid close attention to the impacts of triphenyl phosphate on liver metabolism. We investigated hepatic histopathological, metabolomic and transcriptomic responses of zebrafish after exposure to 0.050 mg/L and 0.300 mg/L triphenyl phosphate for 7 days. Metabolomic analysis revealed significant changes in the contents of glucose, UDP-glucose, lactate, succinate, fumarate, choline, acetylcarnitine, and several fatty acids. Transcriptomic analysis revealed that related pathways, such as the glycosphingolipid biosynthesis, PPAR signaling pathway and fatty acid elongation, were significantly affected. These results suggest that triphenyl phosphate exposure markedly disturbs hepatic carbohydrate and lipid metabolism in zebrafish. Moreover, DNA replication, the cell cycle, and non-homologous end-joining and base excision repair were strongly affected, thus indicating that triphenyl phosphate hinders the DNA damage repair system in zebrafish liver cells. The present study provides a systematic analysis of the triphenyl phosphate-induced toxic effects in zebrafish liver and demonstrates that low concentrations of triphenyl phosphate affect normal metabolism and cell cycle.

Organo-phosphorus flame retardants for unsaturated polyester derived from recycled poly(ethylene terephthalate)

Abstract: In an attempt to suppress the flammability of unsaturated polyesters (RUP) derived from recycled poly(ethylene terephthalate) (PET) and investigate the relationship between flame retardant (FR) chemical structures and their flame retardancy, RUP was incorporated with four organo-phosphorus FRs; triphenyl phosphate (TPP), aluminum hydrogen phosphonate (AHP), diammonium hydrogen phosphate (DAP), and aluminum diethyl phosphinate (OP). The effects of adding FR with regard to the thermal stability of RUP/FR mixtures were investigated via thermogravimetric analysis (TGA). The chemical structure of FR and its mixtures with RUP were determined via FTIR and X-ray photoelectron spectroscopy (XPS). The morphology of the residual char was investigated using a field emission scanning electron microscope (FE-SEM). Flame retardancies were evaluated by a UL-94 vertical test and limiting oxygen index (LOI) measurements. The results indicated that the presence of FR significantly improved the flame retardancy and thermal stability of RUP. LOI values increased from 20 to 28 and V-0 ratings were obtained with an 8 wt% FR loading for DAP and with a 10 wt% FR loading for OP. In contrast, no ratings were recorded for the mixture containing 30 wt% of TPP or AHP. These findings clearly indicate that the efficiency of a phosphorus-based FR depends on the quantity of phosphorus elements within the FR itself, although interactions of the FR with the target polymer should also be accounted for when determining its effectiveness as a FR.

Effects of triphenyl phosphate on styrene suspension polymerization process and flame retardance properties of polystyrene/triphenyl phosphate nanocomposite

Abstract: Preparation of polystyrene nanocomposites containing flame retardants is difficult to achieve in one step by suspension polymerization. Styrene suspension polymerization was studied to determine the effects of the flame retardant on the polymerization process and properties of polystyrene beads. Triphenyl phosphate (TPP) was used in this work, which can dissolve completely in styrene monomers. The results showed that TPP were nanosized spherical particles, distributed homogenously and uniformly in a polystyrene (PS) matrix, and the formation mechanism of TPP nanoparticles was also investigated. In addition, the effects of TPP on the styrene polymerization process were investigated. With TPP amount increasing, the polymerization time increased significantly; molecular weight of PS nanocomposites also decreased and molecular weight distribution became wide; the particle size distribution (PSD) of the PS nanocomposites became wider than pure PS slightly as the particle size decreased. PS/TPP nanocomposites obtained good flame retardance because of nanodispersed TPP particles in its matrix. In a word, the suspension polymerization method provides a facile approach to prepare PS/TPP nanocomposites with better properties.

Polystyrene-based composites and nanocomposites with reduced brominated-flame retardant

Abstract: Polystyrene was melt blended with a halogen-based flame retardant (FR), hexabromocyclododecane, and a non-halogenated FR, triphenyl phosphate (TPP), in a twin-screw extruder. An organically modified montmorillonite (Cloisite 15A) was used to prepare FR polystyrene nanocomposites. The flammability properties and thermal stability of FR polystyrene composites and nanocomposites were investigated. X-ray diffraction analysis showed that the exfoliation structure of organically modified montmorillonite in polystyrene nanocomposites may be achieved by melt-compounding in a twin-screw extruder. Furthermore, a good dispersion of FRs and nanoparticles of organically modified montmorillonite was observed by energy dispersive X-ray analysis. Thermogravimetric analysis demonstrated that the thermal stability of FR nanocomposites enhanced in the presence of clay nanoparticles and antioxidant. The aim of this study was to reduce the FR level, especially in the brominated FRs. The good results obtained by the limiting oxygen index test showed high-performance flammability properties in the composites containing hexabromocyclododecane and TPP, resulted from the synergy effects between these two FRs. However, in spite of producing high thermal performance polystyrene nanocomposites and dispersing clay nanoparticles efficiently into the polystyrene matrix, the flame retardancy properties were deteriorated in the presence of clay nanoparticles. Therefore, the organically modified clay (Cloisite 15A) was not a good synergic compound to improve the flame retardancy of polystyrene nanocomposites.

Physicochemical and Spectroscopic Characterization of Biofield Treated Triphenyl Phosphate

Abstract: Triphenyl phosphate (TPP) is a triester of phosphoric acid and phenol. It is commonly used as a fire-retarding agent and plasticizer for nitrocellulose and cellulose acetate. The present study was an attempt to evaluate the impact of biofield treatment on physicochemical and spectroscopic properties of TPP. The study was carried out in two groups i.e. control and treatment. The treatment group was subjected to Mr. Trivedi’s biofield treatment. The control and treated samples of TPP were characterized using X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR), and ultraviolet-visible (UV-Vis) spectroscopy. XRD study revealed the decrease in crystallite size (6.13%) of treated TPP that might be due to presence of strains and increase in atomic displacement from their ideal lattice positions as compared to control sample. DSC thermogram of treated TPP showed the increase in melting temperature (1.5%) and latent heat of fusion (66.34%) with respect to control. TGA analysis showed the loss in weight by 66.79% in control and 47.96% in treated sample. This reduction in percent weight loss suggests the increase of thermal stability in treated sample as compared to control. FT-IR and UV spectroscopic results did not show the alteration in the wavenumber and wavelength of FT-IR and UV spectra, respectively in treated TPP with respect to control. Altogether, the XRD and DSC/TGA results suggest that biofield treatment has the impact on physical and thermal properties of treated TPP.

Differential interactions of the flame retardant triphenyl phosphate within the PPAR signaling network

Abstract: 1. Abstract Triphenyl phosphate is an organophosphate flame retardant and plasticizer that has been detected in a variety of environmental media and shown to cause weight gain in rats. We hypothesized that triphenyl phosphate would modify the activity of the PPAR: RXR signalling network in a manner that would favor lipid accumulation. Gal4-driven luciferase-based transcription reporter gene assays were used to evaluate the responses of human PPARα: RXRα, PPARγ: RXR α, and the individual receptor subunits, to triphenyl phosphate. Triphenyl phosphate was a potent inhibitor of PPARα: RXRαsignalling. The flame retardant interacted with both the PPARαand RXRαsubunits to inhibit their respective activities at concentrations that were not overtly toxic to the cells. Bioluminescence resonance energy transfer experiments revealed that triphenyl phosphate actually inhibited the dimerization of PPARαand RXRα. In contrast, triphenyl phosphate modestly activated the PPARγ: RXRαreceptor complex. This net activation of the complex was due to strong activation of the PPARγreceptor subunit and modest inhibition of the RXRαsubunit. Further experiments revealed that triphenyl phosphate stimulated pre-adipocyte differentiation to lipid-laden adipocytes at a concentration that disrupted the PPAR signalling network. This dual activity of triphenyl phosphate, as an inhibitor of PPARα: RXRαsignalling and an activator of PPARγ: RXRαsignalling provides a regulatory scenario that could lead to weight gain and other symptoms of metabolic syndrome.
