Fitorremediación de metales pesados (AS, CD Y PB) a partir de dos plantas Pteridofitas en sedimentos del ecosistema de manglar El Salado, Guayaquil- Ecuador

Abstract

Mangroves are plants that grow on land and have a marine-coastal ecosystem. They are at the tropics and subtropics of the planet, there is a species that stands out called Mangrove (Mangle). This type of ecosystem is very diverse which considered by many experts one of the most productive ecological places on the planet, however in recent years it has been affected by pollution from industrial and domestic waste. For this reason, it is important to find Biotechnological strategies, which is phytoremediation, this technique is going to apply from two Pteridophyte plants to preserve mangrove forest of El Salado, which is in Guayaquil- Ecuador. In the present study, the remedial capacity of heavy metals (Arsenic, Cadmium and Lead), bioaccumulation factor and translocation factor was evaluated through 2 pteridophyte plants Dryopteris filix-mas and Pityrogramma ebenea. , distributed in 18 treatments, based on a digestion process and ICP-OES equipment.
