There is good evidence for particulate air pollution to accelerate degenerative aging. The proposed underlying mechanisms relate to inflammation, as particles can inflame lung tissue, thereby contributing to greater chronic inflammation throughout the body in later life. Separately, declining sense of smell correlates with aging as well, particularly with the incidence of neurodegenerative conditions, likely because similar underlying mechanisms contribute to both. Those mechanisms include the chronic inflammation of aging and its disruptive effects on cell and tissue function. Thereby it is perhaps not surprising to see researchers discover a correlation between olfactory decline and air pollution.

Among sensory dysf…
