Toxic cadmium

Metallothioneins (MTs) are cysteine-rich, metal-binding proteins known to provide protection against cadmium toxicity in mammals. Metal exchange of Zn 2+ ions for Cd 2+ ions in metallothioneins is a critical process for which no mechanistic or structural information is currently available.

Cadmium ions are a potent carcinogen in animals, and cadmium is a toxic metal of significant environmental importance for humans. Response curves were used to investigate the effects of cadmium chloride on the growth of Camplyobacter jejuni. In vitro, the bacterium showed reduced growth in the presence of 0.1 mmcadmium chloride, and the metal ions were lethal at 1 mmconcentration.

The nematodeCaenorhabditis elegansexpresses two metallothioneins (MTs), CeMT-1 and CeMT-2, that are believed to be key players in the protection against metal toxicity. In this study, both isoforms were expressedin vitro in the presence of either Zn(II) or Cd(II).

Toxic heavy metals, i.e. copper (II), lead (II) and cadmium (II), can be removed from water by metallurgical solid wastes, i.e. bauxite waste red muds and coal fly ashes acting as sorbents. These heavy-metal-loaded solid wastes may then be solidified by adding cement to a durable concrete mass assuring their safe disposal. Thus, toxic metals in water have been removed by sorption on to inexpensive solid waste materials as a preliminary operation of ultimate fixation. Metal uptake (sorption) and release (desorption) have been investigated by thermostatic batch experiments.
