Abstract

© 2016, Asociacion Espanola de Toxicologia. All rights reserved. Artemia franciscana “brine shrimp”, is sensitive to a wide range of chemical structures, and easy handling in the laboratory and with a relatively simple and inexpensive crustacean culture. The aim of this study was to evaluate the toxicity of parasiticides agent, antimicrobials agent and insecticides on A. franciscana to establish Predicted No-Effect Concentration (PNEC) on marine organisms and obtain guidance levels for the protection of aquatic life. With A. franciscana nauplii II, within 24 h of hatching, we proceeded to perform toxicity bioassays calculating the average lethal concentration (LC50) at 24 h and 48 h of exposure. The following sequence of high to low toxicity to 48 h of exposure to three commercial antiparasitic agents were observed: Mebendazole> Albendazole> Metronidazole. Regarding the lethal toxic effect of six commercial antimicrobial agents about A. franciscana, the following sequence of toxicity at 48 h of exposure was observed: Triclosan> Clotrimazole> Itraconazole> Ketoconazole> oxytetracycline> Mimosa. The brine shrimp mortality showed effects on five substances with insecticidal properties, meeting the following order from highest to lowest mortality at 48 h of exposure Cipermethrin >Rotenone >Carbaryl >Cinnamon >Malathion. The three chemicals were classified as very toxic and presented lower levels guidance for the protection of aquatic life were Triclosan (0,72 ug·L-1), Cipermetrina (0,84 ug·L-1) y Clotrimazol (0,97 ug·L-1). Ten of chemicals (71.42%) showed strong cytotoxic activity.
