Resumen de proyecto de investigación
Mi trabajo de investigación se enfoca en el estudio de la contaminación de suelos agrícolas, especialmente con metales pesados. Estudiamos los factores que regulan la biodisponibilidad y movilidad de estos contaminantes una vez acumulados en el suelo y su transferencia al primer
nivel de la cadena trófica, las plantas. Analizamos tanto plantas silvestres como cultivos agrícolas y sus productos comestibles. Hemos evaluado el potencial de algunas especies nativas para ser empleadas en fitorremediación de suelos. Actualmente estamos investigando enmiendas orgánicas que pueden ser aplicada a los suelos agrícolas contaminados
inmovilizando los metales pesados, de esta manera se puede continuar con el uso agrícola sin que se comprometa la seguridad alimentaria y ambiental.
