A FITORREMEDIAÇÃO COMO INSTRUMENTO ALTERNATIVO NO SANEAMENTO AMBIENTAL

Abstract

The pesticides are substances that perform the pest and disease control in crops. However, overuse causes great environmental impact and damage to human health. For the solution of these problems to phytoremediation was developed as a technique that uses plants to remove, restraint or transformation of soil pollutants. This paper considers data from surveys and analyzes the results and efficiency of this technique. Most of the plants tested as phytoremediator plants are the Leguminosae (53%), followed by Poaceae (38%), Asteraceae (4%), Cruciferae (4%) and Chenopodiaceae (1%). It was observed that species are effective to phytoremediation certain contaminants, may not do the same with others. Different cultivars or hybrid species showed changes regarding your ability to phytoremediation, featuring distinct or similar results against the same pollutants. The technique is promising, but it is need more studies. Index Terms - Adubo verde; agrotóxicos, fitorremediação; impacto ambiental.
