TCHERNITCHIN, Andrei N.  y  GAETE, Leonardo. Influence of environmental pollutants on human gestation: Cause of adult pathologies. Rev. chil. pediatr. [online]. 2018, vol.89, n.6, pp.761-765. ISSN 0370-4106.

This review explains the epigenetic imprinting mechanisms by which the delayed effects generated by prenatal or early childhood exposure to chemical pollutants are produced. Pubmed and Embase databases were reviewed to identify studies published between 2005 and 2018, along with articles considered pioneers in this field. We also included data generated in our Laboratory. As a source of secondary information, Chilean standards on concentrations of some pollutants in drinking water published by the Ministry of Health of Chile are cited. Changes are described in the methylation of diverse genes caused by prenatal or early childhood exposure to some relevant environmental po llutants in Chile such as arsenic, lead, phenols, and phthalates, and some of the organic diseases and neurobehavioral changes that occur later in life as a consequence of these exposures are mentioned. We suggest that a wider knowledge of environmental factors and better education of the population would allow a more adequate protection of pregnant women and infants especially during the win dows of susceptibility, and that pediatricians and obstetricians would be in the best position to deve lop these actions. We also suggest the need to adapt environmental standards and increase the control of pollutants and their sources to prevent health deterioration of future generations.
