The biouptake and toxicity of arsenic species on the green microalga Chlorella salina in seawater

The present study focuses on the biouptake, biotransformations, and toxicity of arsenic species on the marine green alga Chlorella salina in seawater from the Bulgarian Black Sea coast. Exposure to equal concentrations of As(III) or As(V) led to equivalent ...

In vitro breeding of Brassica juncea L. to enhance metal accumulation and extraction properties

Jean-Paul Schwitzguebel, Erika Nehnevajova

In vitro breeding and somaclonal variation were used as tools to improve the potential of Indian mustard (Brassica juncea L.) to extract and accumulate toxic metals. Calli from B. juncea were cultivated on a modified MS medium supplemented with 10–200 μM C ...

Relationship between testate amoebae and atmospheric heavy metals (Pb, Cd, Zn, Ni, Cu, Mn and Fe) accumulated in the moss Barbula indica Hanoi, Vietnam

Edward Mitchell

We studied the relationships between testate amoeba communities and heavy metal (Pb, Cd, Zn, Ni, Cu, Mn, and Fe) concentrations in the moss Barbula indica sampled at 29 sites in and around the city of Hanoi (Vietnam). Our first approach was to compare the ...

Toxicity assessment of the main pesticides used in Costa Rica

Raphael Charles

The impacts of the 30 active substances, most used in Costa Rica (reference year 1998), are evaluated using two models originally developed to support comparative assertions in the context of the life cycle assessment: the multimedia fate, exposure and eff ...

Arsenic sequestration by sorption processes in high-iron sediments

Janet Gordon Hering

High-iron sediments in North Haiwee Reservoir (Olancha, CA), resulting from water treatment for removal of elevated dissolved arsenic in the Los Angeles Aqueduct system, were studied to examine arsenic partitioning between solid phases and porewaters under ...

A Polyoxyethylene-Substituted Bimetallic Europium Helicate for Luminescent Staining of Living Cells

Jean-Claude Bünzli, Anne-Sophie Chauvin, Caroline Vandevyver, Bo Song, Steve Comby

The homoditopic ligand

H_2L^{C3}

has been designed to form neutral triple-stranded bimetallic helicates of overall composition [

Ln_2(L^{C3})_3

]. The grafting of the polyoxyethylene fragments ensures water solubility and also favors cell penetration whi ...

A Promising Technique to Increase Metal Concentration and Extraction in Sunflowers

Jean-Paul Schwitzguebel, Erika Nehnevajova

Since most of the metal-hyperaccumulating wild plants only produce very low biomass and many high-yielding crops accumulate only moderate amounts of metals, the current research is mainly focused on overcoming these limitations and the optimization of meta ...

Non-GMO approach for the improvement of heavy metal accumulation and extraction of high yielding crop species for efficient phytoextraction of contaminated soil

Erika Nehnevajova

Some plants able to take up heavy metals from contaminated soils offer a possibility to clean up sites contaminated with heavy metals. Plants thus act as a solar driven pump, which can extract and concentrate heavy metals from the environment. Since most o ...

Thermal treatment of metal-enriched biomass produced from heavy metal phytoextraction

Christian Ludwig, Catherine Keller

Phytoextraction is an environmentally sound method for cleaning up sites that are contaminated with toxic heavy metals. However, the method has been questioned because it produces a biomass-rich secondary waste containing the extracted metals. Therefore, f ...

Study of peptide on-line complexation with transition-metal ions generated from sacrificial electrodes in thin-chip polymer microsprays

Hubert Girault, Tatiana Rohner

A miniaturized polymer electrospray-type interface is used to study metal-ion chelation with model peptides. Taking advantage of the intrinsic electrochemical behavior of electrospray, a sacrificial electrode is used to generate at the same time electrospr ...
