Advances in analytical methods for speciation of trace elements in the environment,e column unaccompanied by other species of the analyte element, with atomic spectrometry, permitting a sensitive and specific detection of the target element, has become a fundamental tool for speciation analysis, as discussed in many review publications (Caruso et al. 2000; Cornelis et al. 2003; Lo

Analytical strategies for arsenic speciation in environmental and biological samples,n understudied area and only few papers have ever covered this area (Schwedt and Rieckhoff 1996). In contrast to the other members of the group 15 in the Periodic Table of the Elements arsenic does not form oligoanions or polymers like phosphorous or the more metallic antimony. Halogenated arsenic c

Inorganic arsenic compounds are not significantly mutagenic in bacterial test systems or in mammalian cells in culture, but they are clastogenic, causing mainly chromatid type chromosomal aberrations, sister-chromatid exchanges and

Panel discussion: Toxicological Aspects,esis, the high toxicity of many organometal(loid) compounds is due to their high lipophilicity or — in case of the alkylated ionic species — to their amphiphilic properties which both should alleviate the penetration of these compounds through cell membranes. At first sight, this hypothesis seems to

Occurrence and speciation of arsenic, antimony and tin in specimens used for environmental biomonitt, or soil. Rather environmental studies and control have to take into account much more the situation of the biosphere. This includes the transfer of contaminants, mainly of anthropogenic origin, into plants, animals, and finally also into human beings.

The Effect of Phosphate on the Bioaccumulation and Biotransformation of Arsenic(V) by the Marine Altudies have been reported, however, on either the mechanism of arsenic accumulation, or on the algae pathways through which the arsenic is accumulated and biotransformed (Francesconi and Edmonds 1997).
