Bioavailability and speciation of arsenic in carrots grown in contaminated soil

Autor: Erik Huusfeldt Larsen, Hans K. M. Helgesen

Publikováno v: The Analyst. 123(5)

Carrots were grown in seven experimental plots (A-G) containing mixtures of arsenic-contaminated and uncontaminated soil at concentrations ranging from 6.5 to 917 microgram g(-1) (dry mass). The carrots harvested from plots A-D (6.5-338 microgram g(-

The new bimetallic cubane-like cluster [Mo3PbS4(H2O)9+x]4+ was prepared in aqueous 2 mol·dm-3 CF3SO3H in quantitative yield by reaction of [MoIV3S4(H2O)9]4+ with lead powder. Contrary to the case of other clusters of the Mo3M‘S4 type, decompositio
