A.2012-01-12T17:44:51Z2012-01-12T17:44:51Z20070160-4120http://www.repositorio.ufba.br/ri/handle/ri/5150v. 33p. 589–595In spite of the consideration that toxicity testing is a reduced approach to measure the effects of pollutants on ecosystems, the early-life-stage (ELS) tests have evident ecological relevance because they reflect the possible reproductive impairment of the natural populations. The procedure and validation of Crassostrea rhizophorae embryonic development test have shown that it meets the same precision as other U.S. EPA tests, where EC50 is generally used as a toxicological endpoint. However, the recognition that EC50 is not the best endpoint to assess contaminant effects led U.S. EPA to recently suggest EC25 as an alternative to estimate xenobiotic effects for pollution prevention. To provide reliability to the toxicological test results on C. rhizophorae embryos, the present work aimed to establish the critical effect level for this test organism, based on its reaction to reference toxicants, by using the statistical method proposed by Norberg-King (Inhibition Concentration, version 2.0). Oyster embryos were exposed to graded series of reference toxicants (ZnSO4·7H2O; AgNO3; KCl; CdCl2H2O; phenol, 4-chlorophenol and dodecyl sodium sulphate). Based on the obtained results, the critical value for C. rhizophorae embryonic development test was estimated as EC15. The present research enhances the emerging consensus that ELS tests data would be adequate for estimating the chronic safe concentrations of pollutants in the receiving waters. Based on recommended criteria and on the results of the present research, zinc sulphate and 4-chlorophenol have been pointed out, among the inorganic and organic compounds tested, as the best reference toxicants for C. rhizophorae ELS-test.Submitted by Ana Valéria de Jesus Moura (anavaleria_131@hotmail.com) on 2012-01-12T17:44:51Z No. of bitstreams: 1 s2.0-S0160412006001383-main.pdf: 277306 bytes, checksum: 80ebb878104f10628e02ee94894c9fe0 (MD5)Made available in DSpace on 2012-01-12T17:44:51Z (GMT).
