Resumen
[ES] Actualmente, la contaminación de metaloides y metales en el suelo ha ganado una atención considerable. La consolidación de nanomateriales y plantas en la gestión ecológica ha recibido una atención considerable en la investigación porque ciertos nanomateriales podrían mejorar la germinación de semillas de plantas y el crecimiento de la planta completa. Por el contrario, cuando la concentración de nanomateriales no se controla adecuadamente, definitivamente se desarrollará toxicidad. Se han utilizado nanominerales para mejorar la retención de agua y como portadores de nutrientes. Estos nanomateriales promovieron la germinación de semillas, el crecimiento de las plantas, la fijación de fósforo y nitrógeno, frente a los métodos convencionales.
Las nanopartículas también se han utilizado para remediar suelos contaminados por herbicidas, pesticidas, contaminantes orgánicos y metales pesados. Los métodos convencionales de remediación del suelo, como la fitorremediación, el tratamiento térmico y la degradación electrocinética, se han mejorado utilizando nanopartículas.
[EN] Currently, metalloid and metal contamination in soil has gained considerable attention. The consolidation of nanomaterials and plants in ecological management has received considerable attention in research because certain nanomaterials could improve plant seed germination and whole plant growth. On the contrary, when the concentration of nanomaterials is not properly controlled, toxicity will definitely develop. Nanominerals have been used to improve water retention and as nutrient carriers. These nanomaterials promoted seed germination, plant growth, phosphorus and nitrogen fixation, compared to conventional methods. Nanoparticles have also been used to remediate soils contaminated by herbicides, pesticides, organic pollutants and heavy metals. Conventional soil remediation methods, such as phytoremediation, thermal treatment and electrokinetic degradation, have been improved using nanoparticles.
