Chlorinated hydrocarbons: estrogens and antiestrogens

Toxicology Letters, 1995
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) and related compounds bind to the intracellular aryl hydrocarbon (Ah) receptor and induce a diverse spectrum of biochemical and toxic responses. Ah receptor agonists also modulate several endocrine pathways, and research in several laboratories has shown that TCDD and related compounds inhibit estrogen (E2 ...

ChemInform Abstract: CATALYSED DESTRUCTION OF CHLORINATED HYDROCARBONS [PDF]

Chemischer Informationsdienst, 1975
AbstractChlorinated hydrocarbons (CH2Cl2, CHCl3, CCl4, C2H2Cl2, C2HCl3 and C2Cl4) are efficiently converted to HCl and CO2 over Pt/γ‐Al2O3 catalysts on which a hydrocarbon fuel is being oxidised catalytically at about 450°C: conversions generally exceed 95% if the catalyst contains 0.8% or more Pt.

Chlorinated hydrocarbons: oxidation in the biosphere

Environmental Science & Technology, 1982
The review explores the limitations imposed on the biological oxidation of some synthetic compounds, as determined from recent studies with enzymes which catalyze the oxidation of aromatic compounds. Examples are furnished of ways in which existing metabolic pathways can adapt to degrade, or partially degrade, a number of widely used synthetic ...

Chlorinated Hydrocarbons in British Wildlife

Nature, 1967
Polychlorobiphenyl compounds have been detected in British wildlife. In birds' livers and eggs they are often in greater quantities than organochlorine pesticide residues. Polychlorobiphenyls are known to be toxic, and their detection in wildlife raises the question of the adverse effect they may have.

Chlorinated Hydrocarbons in Birds and Mammals

1983
The loss of raptor birds and in particular the peregrine falcon during the use of chlorinated hydrocarbons as pesticides has led to discussion of the means by which these compounds produced their effects. The effect of thinning the egg shells is well known and this may have been the major contribution to the change in reproductive capacity.

PYROLYSIS AND CHLORINATION OF SMALL HYDROCARBONS

Chemical Engineering Communications, 1992
The bases of the kinetic modeling of Chlorine containing systems are addressed in this article A kinetic scheme, involving more than 300 elementary reactions and 46 molecular and radicalic species, has been developed based on general thermochemical kinetic theories as well as the consolidated know-how in the field of hydrocarbon pyrolysis Several ...

Airborne PM2.5/PM10-associated chlorinated polycyclic aromatic hydrocarbons and their parent compounds in a suburban area in Shanghai, China.

Environmental Science and Technology, 2013
Chlorinated polycyclic aromatic hydrocarbons (ClPAHs) have been reported to be formed during incineration processes. Despite dioxin-like toxicities of ClPAHs, little is known on the occurrence of these chemicals in the environment.

Occurrence and source of chlorinated polycyclic aromatic hydrocarbons (Cl-PAHs) in tidal flats of the Ariake Bay, Japan.

Environmental Science and Technology, 2013
In this study, we hypothesize that natural photochemical reactions of polycyclic aromatic hydrocarbons (PAHs) in tidal flats are responsible for the occurrence of chlorinated polycyclic aromatic hydrocarbons (Cl-PAHs).

Integrated carbon and chlorine isotope modeling: applications to chlorinated aliphatic hydrocarbons dechlorination.

Environmental Science and Technology, 2013
We propose a self-consistent method to predict the evolution of carbon and chlorine isotope ratios during degradation of chlorinated hydrocarbons.
