Abstract

The aim of this study was to compare the effects of Remazol Brilliant Blue R (RBBR) and polluted urban streams on the Biomphalaria tenagophila embryonic development test, in comparison to the Daphnia magna reproduction test. Eggs of B. tenagophila and D. magna neonates have been exposed to RBBR (10 and 25 mg L–1 coloring concentrations) and 50% diluted and not diluted stream water. The dye was ineffective in alter the hatching rate, development and embryo mortality (p > 0.05). The reproduction of D. magna showed significant difference (p < 0.05) compared to control in both coloring concentrations. The stream water caused embryo mortality between 10 and 12 days in both cases. The neonates number and the mortality of D. magna differed significantly from the control only in the exposed undiluted stream water. The results from this study indicated that B. tenagophila embryos were more susceptible to complex mixtures in freshwater than D. magna, proving its usefulness as biological indicator in aquatic toxicity biomonitoring.
