Odours count: human olfactory ecology appears to be helpful in the improvement of the sense of smell

Abstract Odours modify human behaviour. Research in this field develops rapidly, providing more and more exciting discoveries. In this context, our daily odorous environment has been surprisingly poorly explored. The aim of our study was to quantify olfactory perception and preliminarily identify fa...
