Avaliação da capacidade de fitorremediação de octocrileno por Salvinia biloba Raddi Emend La sota

Abstract

Octocrylene is present in many types of cosmetic and personal care products that are used around the world. The regular use of these products causes different compounds to be released in water and soil, making them potential contaminants in different ecosystems. Most of these compounds are classified as emerging pollutants because they are not included in environmental monitoring programs, since the extent of the risks they pose to the environment is still unclear. Based on this, this TCC seeks to verify through activity analysis enzymatic and Toxicity analysis in Allium cepa, whether Salvinia biloba La sota has the potential to treat octocrylene contamination at concentrations of 200 µg/L, 400 µg/L and 600 µg/L. With the results of the analyzes carried out at 24h, 48h and 96h of the experiment, we observed that the activities of the enzymes catalase, ascorbate peroxidase, guaiacol peroxidase and superoxide dismutase indicate that S. biloba fought octocrylene in its physiological system. Chlorophyll analyzes confirm the stress suffered by the plant. Even the analysis of toxicity in A. cepa in the solution after treatment indicates the contamination of A. cepa, with the analysis of all these data we can say that Salvinia biloba La Sota does not have the capacity to treat octocrylene, only to withstand exposure to the contaminant .
