Abstract

ABSTRACT

In 2008 Mariani et al. performed a five-years retrospective statistical analysis of 575 patients showing a significative correlation between frequence of PPV attacks and air pollution peaks. Analysis showed that PPV is a cyclic phenomenon and that it could be correlated to pollution.
As far Author’s knowledge concern, no other papers has been yet published regarding correlation between PPV and environmental phenomena.
This paper confirms these observations along a ten years course regarding NO2 and ultra-fine particles (ppm10). Some speculations about how environmental factors may interfere with metabolism of inner ear endolimph metabolism causing free floating particles are presented
