Vinylic and Waterproofing Paint with TiO2 as Photocatalytic Active Effects in Lolium Perenne Germination

Abstract

There are studies that show the presence of TiO2 nanoparticles may have ecotoxic consequences in vegetable species germination process, even though benefits of TiO2 have been found as a photocatalytic active for CO2 conversion into O2 reducing the concentration of this greenhouse effect gas. The present paper aims to analyze the Lolium perenne germination and its growing when being exposed to vinylic and waterproofing paint with TiO2 active, concentration curves of CO2 and O2 were determined, in addition to L. perenne growing as being exposed to the active. Seeds, seedling, and the former L. perenne plant were analyzed to determine the presence of Ti using SEM and EDS-RX microanalysis to determine if it is possible to use TiO2 as a CO2 remediator without repercussions in vegetable species such as L. perenne.
