Aluminium is an ubiquitous element of which the various forms (e.g. complexed forms of Al) have a widely differing toxicity to biota and humans. The evaluation of this toxicity with regards to Al-species and total Al is often hampered by the lack of available analytical methodology.
Aluminium is toxic to plants and accumulates especially in roots. The toxicity may be caused by interferences in cell multiplication in the root, binding of phosphorus, decrease in enzymatic activities, changes in the cell walls and interferences in resorption and transport of Ca, Mg, P, K and even water.
Al which is accessible to aquatic biota (e.g. fish) is known to be highly toxic to them. Aluminium is toxic to humans. Patients submitted to dialysis are the most exposed to Al contamination (dementia, anemia). Al is also suspected to be linked with Alzheimer's disease (senile dementia). The project will start with a feasibility study consisting of the study of the stability of a number of complexed forms of Al in aqueous solutions. Following this, intercomparisons will be organized for the determination of Al-species in solutions. At the end of the project it is hoped to study the speciation of Aluminium in soil.
STATUS
Feasibility study to be concluded by the end of 1992.
