title: Urinary 1-hydroxypyrene concentration from Mexican children living in the southeastern region in Mexico.
abstract: Biomass combustion indoors has been associated with generation of various pollutants, such as carbon monoxide, formaldehyde, respirable particles, toluene, benzene and polycyclic aromatic hydrocarbons (PAHs), among others. In this context, the aim of this study was to evaluate the urinary 1-hydroxypyrene (as a biomarker exposure to PAHs) levels in children living in three states in Mexico. We evaluated children living in communities that use biomass fuels to cook and to heat homes in the next states: Chiapas, Oaxaca and Quintana Roo. We found similar levels of 1-OHP in urine of children living in the three studied states, with mean levels of 3.5 ± 1.0; 4.5 ± 2.8 and 4.4 ± 2.5 μg/L (geometric mean ± standard deviation), respectively for Chiapas, Oaxaca and Quintana Roo. In conclusion, our data indicate high exposure levels to PAHs in children living in the states studied in this work.
