ZAFRA-MEJIA, Carlos; BELTRAN-VARGAS, Julio  and  HERNANDEZ-PENA, Yolanda. Pollution And Public Health In Urban Habitats: Heavy Metals In Road Sediments Of Bogota, Colombia. Rev.EIA.Esc.Ing.Antioq [online]. 2020, vol.17, n.33, pp.1-14. ISSN 1794-1237.  https://doi.org/10.24050/reia.v17i33.1247.

Research agencies in urban planning, environment, and public health report the growing interest of studying the pollution by heavy metals (HMS) in urban habitats. A descriptive observational study of the HM concentrations in road sediments of an urban habitat in Latin America is displayed: Bogota-Colombia. There was a coincidence between the HM concentrations reported worldwide and those observed in Bogota. Concentrations in Bogota tended to be lower than those reported in cities of North America, Europe, and Asia. The most critical element was Pb. The concentrations of Pb exceeded between 1.02-4.30 times the legislative limit most demanding for ingestion, inhalation, and dermal contact (Catalonia-Spain: 60 mg/kg). During climatic periods of dry time there were increases in HM concentrations (between 1.31-2.11 times). The findings are a point of reference during the development of strategies for the protection of the public health and environment in urban habitats.

Keywords : urban habitats; heavy metals; public health.
