AQUATIC SPECIES OF THE WETLANDS OF BOGOTÁ, COLOMBIA WITH CAPACITY FOR THE TREATMENT OF WASTEWATER WITH HEAVY METALS: REVIEW

Abstract

The present study seeks to recognize that aquatic species with presence in Bogotá wetlands can treat wastewater according to the type of heavy metals and thus present the information in such a way that the community can generate design processes more efficiently. The above avoid the use of exotic species or that are not useful for the retention and / or absorption of certain heavy metals. The methodology used began with a compilation of the information of all aquatic species with presence in the city's wetlands, later the database search was carried out for each species on the capacity of bioaccumulation of heavy metals and finally, it was analyzed and I order the information found. As result, 48 aquatic species were found, of which 24 species do not have any information, 14 require a more detailed review, 1 species (utricularia gibba) cannot be used in treatment processes due to its high sensitivity to changes in the ecosystem and species such as holcus lanatus are highly selective with respect to resistance and accumulation of heavy metals, the remaining 24 species show a variable capacity in accumulation and is affected by factors such as pH and concentration of heavy metals; It can be concluded that the species present in the Bogotá wetlands are not hyper accumulative and that the use of native plants should be encouraged as they do not act as invasive plants, thus avoiding the risk of displacing native or endemic species..
