Manganese (Mn), although an essential trace element, is of
growing concern as a toxic air pollutant. It is not only readily
transported from the olfactory epithelium (OE) to the olfactory
bulb but, unlike other metals, is also transported transsynaptically
to structures deep within the brain. However, to our knowledge
no information is available on the possible effect of nonoccupational
exposure to Mn on olfactory function. We therefore
investigated peripheral and central olfactory performance in a
non-occupationally Mn-exposed population. Using the Sniffin’
sticks test battery, we compared the olfactory performance of
two groups (n = 30/group) from a Mn mining district in central
Mexico: an exposed group living
