Using the Sniffin Sticks olfactory test battery and an established test for intranasal trigeminal function we compared the olfactory performance and trigeminal sensitivity of 30 young adult residents of Mexico City, a region with high air pollution, with the performance of an equivalent control population from the neighboring Mexican state of Tlaxcala, a less polluted region (15 men and 15 women for each region, all non-smokers). Subjects from Mexico City had significantly lower scores than subjects from Tlaxcala in the olfactory threshold and discrimination tests, as well as in the test of trigeminal sensitivity. We conclude that Mexico City air pollution impairs olfactory function and intranasal trigeminal sensitivity, even in otherwise healthy young adults.
