    Phytormediation is an exciting new method for controlling and cleaning up hazardous wastes using green plants. This book is the first to compile the state of the science and engineering arts in this rapidly advancing field. Phytormediation: Approaches the subject from the perspectives of biochemistry, genetics, toxicology, and pathway analysis. - Is written by two of the premier experts in.   Patty's Toxicology presents a premier reference for toxicological information on a large number of industrial chemicals that pose potential health hazards. The reference presents logical groupings of comprehensive toxicological data for industrial compounds, including CAS numbers, physical and chemical properties, exposure limits, and biological tolerance values for occupational .

    Phytoremediation: Transformation and Control of Contaminants provides an authoritative account of the history and the most recent developments of this exciting, emerging field. Steven McCutcheon and Jerald Schnoor's insightful book defines the current state of the science of phytoremediation and points the way to further possible by:   A halogenated hydrocarbon is a hydrocarbon that contains one or more halogen atoms. The chemical compound is also known as a halocarbon. The chemical compound is also known as a halocarbon. Examples.

    Halogenated means that all of these chemicals have one or more halogen atoms attached to their benzene rings. The enzyme activity of isolated protein was ent transformation of 2. Halogenated hydrocarbons may be sub-classified based on the nature of the hydrocarbon fragment to which they are attached (alkane, alkene, alkyne, aromatic), and on the basis of the number of halogen atoms present (mono-, di- tri- tetra-, etc. halogenated compounds).File Size: 57KB.

The reactions of alkanes with halogens produce halogenated hydrocarbons, compounds in which one or more hydrogen atoms of a hydrocarbon have been replaced by halogen atoms: The replacement of only one hydrogen atom gives an alkyl halide (or haloalkane).

Transformations of halogenated hydrocarbons: hydrolysis and redox processes Author: N Lee Wolfe ; Peter M Jeffers ; Environmental Research Laboratory (Athens, Ga.). The occurrence of halogenated hydrocarbons as ubiquitous contaminants in the environment is well documented (Vogel et al., ). Specific compounds in this class of organics are widely used as industrial cleaning and degreasing solvents, high pressure lubricants, pesticides, and coolants (including proposed freon substitutes).

In an interesting study on bioremediation of hazardous wastes, aromatic hydrocarbons such as benzene, toluene, ethyl benzene, xylenes, phenols, and cresols were used as electron donors to biologically reduce halogenated hydrocarbons (electron acceptors) such as tetrachloroethylene (PCE) and trichloroethylene (TCE), thereby achieving the degradation of both (U.S.

Patent No. Request PDF | Biogeochemistry of Halogenated Hydrocarbons | This chapter will describe the widespread occurrence of halogenated hydrocarbons, interpret their distribution and biogeochemical. Halogenated hydrocarbons are derivatives of hydrocarbons (that is, organic compounds that only contain carbon and hydrogen atoms) which include some halogen atoms within their chemical most commonly encountered halogens in halogenated hydrocarbons are fluorine and chlorine, but sometimes bromine or iodine occur, or combinations of any of these.

All products detected were aromatic, and substituents were often oxidized but were not separated from the benzene ring. Most transformations were enhanced by (NH 4) 2 SO 4 ( mM) and were prevented by C 2 H 2, a mechanism-based inactivator of ammonia monooxygenase (AMO).
