Due to this fact, it is commonly used in fragrances and as a flavor additive. alkaline, earthy, metallic, nonmetallic or radical base). More impurities were generated under acidic, basic, light, and oxidative forced degradation conditions relative to thermal degradation, however thermal exposure is the most likely adverse condition to be experienced by these products. 0000022277 00000 n 0000000900 00000 n 0000005244 00000 n 13 .

ZnO-np exposure experiments to nematodes found that biological responses can be independent of the free ion concentration and that different toxicity … As a fuel for marine and ultra-light camping (backpacking) stoves. Even if impurities are present in MPA injectables, QSAR analysis found that known impurities for MPA are apparently no more of a safety risk than MPA. 0 The bioassays were performed in triplicate. Subacute toxicity of 14 nm nanoparticulate silver (Ag-NP) stabilised with polyvinylpyrrolidone and ionic silver in the form of silver acetate (Ag-acetate) was investigated in four-week-old Wistar rats. Degradation ability of Thielavia sp for NP, 4-tert-OP and 2,4-DCP was evaluated. We use cookies to help provide and enhance our service and tailor content and ads. The objective of the present study was to evaluate the ability of the ascomycetes Thielavia sp HJ22 to remove the phenolic xenobiotics nonylphenol (NP), 4-tert-octylphenol (4-tert-OP) and 2,4-dichlorophenol (2,4-DCP). 0000002199 00000 n %%EOF Copyright © 2020 Elsevier B.V. or its licensors or contributors. 0000001276 00000 n trailer 0000000977 00000 n 0000022533 00000 n The results point out the potential of Thielavia strains in the degradation and detoxification of phenolic xenobiotics. Results and discussion 3.1. Acetate removal leads to aggregation of the ZnO-np primary particles but promotes greater surface reactivity. Forced degradation studies were conducted on MPA and MPA injectables to gain a better understanding of potential sources of impurities and degradation products. Furthermore, QSAR analysis was conducted to assess the toxicity risk of known impurities. Degradation metabolites showed reduced toxicity compared to the parent compounds.

Liquid chromatography-mass spectrometry analysis revealed several intermediates, mainly hydroxylated and oxidized compounds with less harmful effects compared to the parent compounds. The metabolic pathways of degradation were proposed based on the identified metabolites. A decrease in the toxicity of the identified metabolites was observed using Aliivibrio fischeri as bioindicator. 6 0 obj <> endobj 0000023563 00000 n Removal was associated with laccase and biosorption process.

Analytical methods are available that quantify impurity levels in MPA and MPA injectable products, but minimal information is publicly available on the source of impurity and degradation product generation or the safety risk of these compounds. A removal rate of 80% was observed with 2,4-DCP within the same time.
