Comparing the effectiveness of chronic water column tests with the crustaceans

Standard U.S. Environmental Protection Agency laboratory tests are used to monitor water column toxicity in U.S. surface waters. The water flea Ceriodaphnia dubia is among the most sensitive test species for detecting insecticide toxicity in freshwater env ...

Esfenvalerate toxicity to the cladoceran Ceriodaphnia dubia in the presence of green algae, Pseudokirchneriella subcapitata

The presence of phytoplankton, like other particulate organic matter, can interfere with the effects of hydrophobic contaminants such as pyrethroid pesticides. However, the reduction or elimination of toxicity by algae added as food during testing is not t ...

Functional diversity of reductive dehalogenases in a bacterial consortium degrading chloroethenes

Christof Holliger, Julien Maillard, Géraldine Florence Buttet

Enrichment cultures are investigated for the bioremediation potential of tetrachloroethene (PCE). This process is based on anaerobic respiration in which chlorinated compounds are used as electron acceptors (organohalide respiration, OHR). The key enzyme i ...

Functional diversity of reductive dehalogenases in a bacterial consortium degrading chloroethenes

Christof Holliger, Julien Maillard, Géraldine Florence Buttet

Several enrichment cultures were investigated in our laboratory for the bioremediation potential of tetrachloroethene (PCE). The underlying process, organohalide respiration (OHR), is based on bacterial anaerobic respiration in which the chlorinated compou ...

Effects of different soil amendments on phytoremediation from a cadmium and DDTs co-contaminated soil by Sedum alfredii (Cd hyperaccumulator) co-cropped with Ricinus communis (DDT accumulator)

Pauline Grandjean

Soil pollution is a major environmental problem actually in China and in the world. It increases environmental risks and can affect humans through the food chain. Like solutions to clean-up the soils are generally expensive and can have side effects on env ...

GENETIC INSTABILITY OF THE DEHALORESPIRATION PROCESS IN DESULFITOBACTERIUM HAFNIENSE STRAIN TCE1

Christof Holliger, Julien Maillard, Aurélie Duret

Dehalorespiration is an environmental-friendly bacterial anaerobic respiration that couples reductive dechlorination of chlorinated organic pollutants with energy conservation. Tetrachloroethene (PCE) respiration is encoded by the pce gene cluster in Desul ...

Occurrence of persistent toxic substances in soils, sediments, fishes and human breast milk in southern Vietnam

Ngoc Vinh Nguyen

Global contamination and toxic effects of persistent toxic substances (PTSs) have been an emerging environmental issue and have received considerable attention during the past four decades. The rapid agricultural and industrial growths as well as the expan ...

Dynamic feature selection for hardware prediction

Babak Falsafi

Most hardware predictors are table based (e.g. two-level branch predictors) and have exponential size growth in the number of input bits or features (e.g. previous branch outcomes). This growth severely limits the amount of predictive information that such ...

Lindane and Technical HCH Residues in Indian Soils and Sediments: A Critical Appraisal

Jean-Paul Schwitzguebel, Sylvie Vullioud-Marcacci

Even at low residue concentrations, persistent organic pollutants (POPs) are of increasing concern all over the world. They include numerous organochlorine pesticides, like hexachlorocyclohexane (HCH), known for its toxicity, lipophilic properties and very ...
