Comparative embryotoxicity of phenanthrene and alkyl-phenanthrene to marine medaka (Oryzias melastigma)

open access: yesMarine Pollution Bulletin, 2014
Alkylated polycyclic aromatic hydrocarbons (alkyl-PAHs) are the predominant form of PAHs in oil, comprising 85-95% of total PAHs. However, little attention has been paid to these chemicals in ecological risk assessment of marine oil spill. A comparative study of the toxic effects of phenanthrene and retene (7-isopropyl-1-methylphenanthrene, an alkyl ...

Mutagenicity of phenanthrene and phenanthrene K-region derivatives

Mutation Research/Genetic Toxicology, 1979
Phenanthrene and 9 K-region derivatives, most of them potential metabolites of phenanthrene, were tested for mutagenicity by the reversion of histidine-dependent Salmonella typhimurium TA1535, TA1537, TA1538, TA98 and TA100 and the rec assay with Bacillus subtilis H17 and M45.

Light gas solubility in phenanthrene: the hydrogen—phenanthrene and methane—phenanthrene systems

Fluid Phase Equilibria, 1990
Abstract A variable volume equilibrium cell was used to study the hydrogen—phenanthrene and methane—phenanthrene systems. The data were taken along isotherms from 398.2 to 473.2 K and up to pressures of 25.23 MPa. Henry's constants and heats of solution were calculated for both systems.

BIODEGRADATION OF PHENANTHRENE IN SOIL

Journal of Environmental Science and Health, Part B, 2001
We investigated the potential of an aerobic polycyclic aromatic hydrocarbon (PAH)-adapted consortium to degrade phenanthrene in soil. Optimal degradation conditions were determined as pH7.0 and 30 degrees C with a water content of 100% wt soil/wt water (w/w).

The electron affinity of phenanthrene

The Journal of Chemical Physics, 2006
Phenanthrene is studied by photodetachment-photoelectron spectroscopy. Due to the absence of a parent ion peak in the anion mass spectrum the electron affinity could not be determined directly. However, this absence is the first indication that this molecule has a negative electron affinity. The first three water complexes of phenanthrene were studied,

Thermoluminescence of phenanthrene

Journal of Luminescence, 1975
Abstract The thermoluminescent emission of phenanthrene crystals, UV excited at liquid N2 temperature, is investigated on the basis of a previously proposed kinetic model. It is found to fit quantitatively the glow peak shape and some evidence is obtained that radiative recombinations take place through a two-step process.

The ozonolysis of phenanthrene)

Recueil des Travaux Chimiques des Pays-Bas, 1959
AbstractPhenanthrene reacts quickly with one mole of ozone at the 9,10‐double bond. In chloroform a polymeric mono‐ozonide (II) is obtained, which can be converted into diphenic acid. In methanol the reaction takes a different course resulting in the formation of a cyclic methoxy‐hydroxy‐peroxide (V) and a cyclic dimethoxy‐peroxide (VI).
