This study aimed to evaluate the efficiency of the aquatic macrophytes Salvinia auriculata Aublet in purification of polluted effluents, and evaluate macroscopically the efficiency of macrophytes using the Allium cepa Linnaeus (onion test). Three collections were performed in September 2011, the first analysis was performed with water collected directly from River Santa Catarina, the second was performed seven days after the contact of the effluent with the macrophytes, and the third, fifteen days after the first analyses. The data were analyzed using Student’s t-test (p<0.05). To verify the normality of the data was used the Kolmogorov-Smirnov test (p<0.05), for each sample (treatment). According to the results of the Allium test, the aquatic macrophyte S. auriculata was efficient in the removing of pollutants agents after fifteen days in contact with the effluent.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
