The relationship between polycyclic aromatic hydrocarbons exposure and serum klotho among adult population

Klotho is an important factor involving aging process. Recently, polycyclic aromatic hydrocarbons (PAHs) exposure was reported to have adverse impact on DNA methylation associated with aging. The aim of the cur‑ rent study was to determine the relationship between serum klotho and PAHs exposure in an adult population.
