La presencia de metales pesados en suelos a causa de la industria minera es una constante que afecta de forma directa e indirecta al ecosistema, principalmente al recurso suelo; ante esta problemática surge la técnica de fitorremediación como alternativa de solución, en tal sentido el objetivo de esta investigación es diseñar una propuesta ambiental de fitoextracción de metales pesados (arsénico, cadmio y plomo) a partir de la comparación de tres géneros vegetales, para la restauración de suelos contaminados por la minera Quiruvilca S.A – La libertad 2020; el diseño que se aplicó en la investigación fue no experimental longitudinal de tipo descriptiva – propositiva, el cual consistió en la búsqueda, selección y análisis de resultados de los estudios de investigación seleccionados, para luego realizar un diagnóstico en base al D.S Nº 011-2017 MINAM-ECA para suelo,...
