“…Oxidation. Several studies have shown photooxidation and biological oxidation to be important conversion paths for halogenated hydrocarbons; for reviews see Mill [ 171, Atkinson [ 181, and Gibson [19]. Given the complexity of the various factors that influence the course of oxidation processes, it has not been possible to model reaction rates in water ecosystems satisfactorily.…”

The degradation of several classes of halogenated aromatic hydrocarbons in methanogenic sediment‐water systems was examined in laboratory studies. Several transformation processes were shown to occur, leading to formation of a variety of products. In the study a clear distinction could be made between transformation processes taking place immediately upon incubation of the compounds and processes taking place after a characteristic period of varying length. γ‐Irradiation was used to quench biological reactions and thus assess the impact of those processes on the overall rates of degradation of the studied compounds. The kinetics of both the initial and the final processes were pseudo‐first‐order, with half‐lives ranging from <0.46 d to no detectable degradation for a number of multiply halogenated benzenes. Compounds were selected with the aim of obtaining a maximum variation in chemical reactivity and physical properties. The sediments were selected with the aim of assessing several environmental factors influencing the kinetics of reduction.

“…Aromatic compounds are widespread in the environment. They originate from biosynthesis, natural diagenesis, and human activity (22). Important biological sources of aromatic ring structures are the amino acids phenylalanine and tyrosine and the rigid biopolymer of trees, lignin.…”

Immunological demonstration of a unique 3,4-dihydroxyphenylacetate 2,3-dioxygenase in soil Arthrobacter strains

Many bacteria biosynthesize 3,4-dihydroxyphenylacetate 2,3-dioxygenases for growth on aromatic acids, but gram-negative organisms have been most extensively studied. A gram-positive strain containing 2,3-dioxygenase activity was identified as Arthrobacter strain Mn-1. The 2,3-dioxygenase from strain Mn-1 was purified to homogeneity by fast protein liquid chromatography with a Mono Q anion-exchange column. Rabbit polyclonal antidioxygenase antibodies were prepared. Ouchterlony double-diffusion and Western blotting (immunoblotting) protocols were used to probe the distribution of the Mn-1 dioxygenase antigen in soil bacteria. Fourteen 2,3-dioxygenase-containing BaciUus and Pseudomonas strains did not contain immunologically cross-reactive proteins. Six of eight Arthrobacter strains contained 2,3-dioxygenase activity, and all of them produced cross-reactive proteins. The data presented here suggest that a unique type of dioxygenase is geographically widespread but is taxonomically confined to Arthrobacter soil bacteria.

ATSDR evaluation of potential for human exposure to benzene

et al. 2008

View full text Add to dashboard Cite

As part of its mandate, the Agency for Toxic Substances and Disease Registry (ATSDR) prepares toxicological profiles on hazardous chemicals found at Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) National Priorities List (NPL) sites that have the greatest public health impact. These profiles comprehensively summarize toxicological and environmental information. This article constitutes the release of portions of the toxicological profile for benzene. The primary purpose of this article is to provide interested individuals with environmental information on benzene that includes production data, environmental fate, potential for human exposure, analytical methods, and a listing of regulations and advisories.
