Only minimal information is available concerning the distribution of indium tin oxide (ITO) particles inside the body.


A considerable amount of ITO particles could still be observed in the lung of hamsters even 78 weeks after the last application. This result indicates that the residual particles might be the cause of the detected lung damage. Moreover an increasing amount of dissolved indium could be detected in the serum of the animals. This suggests that at least a fraction of the particles is soluble. Different particles, e.g. ITO in comparison to indium phosphide (InP), show different dissolution behavior.

No distribution data could be found for ITO particles in particular. However soluble indium distributes relatively even among the major organs of rats (liver, kidney, lung, spleen and testes) after intratracheal instillation of indium phosphide (InP).
