In the laboratory, marine worms were fed with a mixture of algae and several aliphatic hydrocarbons for 15 days. By comparing hydrocarbons in food and in faeces, it appeared that the worm's digestive process led to changes in the distribution of the n-alkanes mixture. These changes were different from those only due to physical processes in the experimental conditions, indicating that marine wo...

The dechlorination of chlorine containing hydrocarbons in pyrolysis vapor is poorly understood. In order to shed new light on the mechanism, a model mixture composed iso-octane doped with 2-chlorobutane, 2-chloroethylbenzene, and chlorobenzene was used study chlorinated by alkali adsorption. These three were selected as they can be typically produced from mixed plastic waste polyvinyl chloride ...

Molecular/theoretical modeling studies have revealed that thyroid hormones and toxic chlorinated aromatic hydrocarbons of environmental significance (for which dioxin or TCDD is the prototype) have similar structural properties that could be important in molecular recognition in biochemical systems. These molecular properties include a somewhat rigid, sterically accessible and polarizable aroma...

Volatile organic chemicals present at Superfund sites preferentially partition into the soil gas and may be available for microbial degradation. A simple mass transfer model for biodegradation for volatile substrates has been developed for the aerobic decomposition of aromatic and aliphatic hydrocarbons. The mass transfer analysis calculates diffusive fluxes from soil gas through water and memb...

The non-methane organic compounds (NMOCs) released from municipal solid waste (MSW) landfills impose significant impact on the environment and human health. It is necessary to investigate the fugitive emission of NMOCs from MSW landfills for helping control NMOC emissions and reduce the environmental impacts. This study was focused on the concentration distribution of NMOCs on the operating and...

In the original version of this Article, Affiliation 2 was omitted for Qinghua Zhang. In addition, there were typographical errors. In the Results section under subheading 'Chromatographic separation' " The peak resolution factors (R s) of these chiral compounds were generally high than 1 except for PCB-174 and-83 " now reads: " The peak resolution factors (R s) of these chiral compounds were g...
