Ecotoxicological Evaluation of Aquatic Environment Contamined by Diesel and Biodiesel Using Daphnia similis as Test Organism

Abstract

This study aimed to evaluate the ecotoxicity of an aquatic environment contaminated with Diesel S10 and Biodiesel B100, using Daphnia similis as the test organism. For this purpose, ecotoxicological tests were performed based on the ABNT NBR 12713 standard, during which the Daphnia were exposed to different test solutions of the fuels for 24 and 48 hours. The results demonstrated that exposure to Diesel S10 caused significantly more severe effects than exposure to Biodiesel B100. These data highlighted that Diesel S10 has a higher toxic potential in aquatic environments than Biodiesel B100.
