Aluminium Oxides – Behaviour

Aluminum and aluminum oxide particles are taken up in the cells. They tend to agglomerate unless stabilised by means of additives.

The blood-brain barrier as a barrier to aluminum and aluminum oxide particles has been little studied so far. A damaged blood-brain barrier by high pressures or overdosing may be permeable to nanoparticles.

Few studies have examined the behavior of engineered aluminum nanoparticles in the environment. Generally, the solubility of these particles is considered to be low, i.e. only a few ions dilute from the particles in aqueous solution [1]. Under acidic conditions, however, increases the solubility, and more ions get into soil or water. Ions were described as toxic to the roots of crops.
