CASTILLO, Marco Antonio Martínez et al. Evaluation of exposure to polycyclic aromatic hydrocarbons, renal and respiratory health in the indigenous population of Tocoy, San Antonio, S.L.P, México. Acta toxicol. argent. [online]. 2022, vol.30, n.3, pp.3-3. ISSN 1851-3743.

Interior air pollution is a public health concern, it affects about 2.6 billion people around the world who still cook using solid fuels such as wood, crop wastes, among others. This exposition increases the risk of the development of non-communicable diseases (NCDs). The indigenous population is very susceptible to being exposed to mixtures of pollutants from the wood smoke such as Polycyclic Aromatic Hydrocarbons (PAHs) due to traditional methods of cooking, heating and waste burning. Therefore, the objective of this work was to evaluate the exposure to PAHs through the application of 10 hydroxylated metabolites (OH-PAHs) in the urine of the indigenous population from the Huasteca Potosina, this by gas chromatography coupled to mass spectrometry and to assess renal health of the population at the time of the study, with a general test of urine and through the uremic toxin Indoxyl Sulfate (IS), this by high-performance liquid chromatography, and the and pulmonary health with spirometry. The results indicate the presence OH-PAHs in 89.47% of the urine samples, the most frequent metabolites were 1-OH-PYRENE, 2-OH-NAPTHALENE. IS was present in 100% of the samples in mean concentrations of 193.4 ± 91.85 gg/L. For pulmonary health, the results indicate some subjects have regular and irregular respiratory patterns. These results indicate that the population is highly exposed to a mixture of pollutants in the air that might damage the lungs and kidneys and increase the risk of NCDs development.
