Biovolatilisation of metal(loid)s by microorganisms,als (e.g. Bi, Hg, Sn), metalloids (e.g. As, Sb) and non-metals (e.g. S, Se, Te). Decisive for the mobility of a certain element species is its affinity to solid matrices, its solubility in solvents, and its volatility. Consequently, physical, chemical and biochemical reactions, which change these pr

The Effect of Phosphate on the Bioaccumulation and Biotransformation of Arsenic(V) by the Marine Algh concentrations of arsenic occur in macroalgae with concentration factors of 1000 to 10,000 reported (Cullen and Reimer 1989; Francesconi and Edmonds 1993; Francesconi and Edmonds 1997), and algae seem to be able to accumulate arsenic more efficiently than the higher members of the food web.

Current aspects on the genotoxicity of arsenite and its methylated metabolites: Oxidative stress anincluding copper, zinc and lead smelters or glass manufacturing, as well as during the production and use of pesticides and herbicides (IARC 1980). Although the commercial use of arsenicals has been largely reduced over the last decades, there is, nevertheless, persistent concern about high levels o

Cytogenetic investigations in employees from waste industries,r detecting biological effects of ionising radiation. In 1964 Pollini reported chromosomal alterations in bone marrow cells and peripheral lymphocytes of a patient suffering from benzene haemopathia. During the following years more and more cytogenetic investigations of groups of people exposed to c

Actions of metals on membrane channels, calcium homeostasis and synaptic plasticity, long-term potentiation. The results focus on experiments conducted over the last decade. Due to the importance of lead, the actions of this metal are emphasized in this report, while the actions of other metals such as mercury, zinc and aluminium as well as the organic metal compounds triethyllead
