Resumo: | In this study the acute and sub-lethal effects caused by the Water Soluble Fraction (WSF) of a light crude oil were assessed for the first time on the planktonic copepod Acartia tonsa. Chromatographic analysis was also performed to quantify the levels of hydrocarbons (total, aliphatic and polyaromatic hydrocarbons) to which copepods were exposed to. Male and female individuals were exposed to hydrocarbon concentrations varying from 12 to 196 μg.L–1 (Total hydrocarbons). The LC50 was 69.5 (24 hours) and 48.0 μg.L–1 (48 hours) for females and 84.8 (24 hours) and 70.1 μg.L–1 (48 hours) for males. Sub-lethal effects were also evaluated by exposing females to the equivalent of LC10. Females showed significant reduction in egg and fecal pellet production, and also a delay in the eggs hatching time. Thus, the toxic effects of WSF of oil may be crucial for the specie population maintenance, possibly influencing the equilibrium of marine ecosystems. |

Análises de cromatografia foram realizadas na FSA para determinar as concentrações de hidrocarbonetos (totais, alifáticos e aromáticos) a que foram submetidos os organismos. Machos e fêmeas foram expostos a concentrações que variaram entre 12 e 196 μg.L–1 (hidrocarbonetos totais). As CL50 foram de 69,5 (24 horas)e 48,0 μg.L–1 (48 horas) para fêmeas e 84,8 (24 horas) e 70,1 μg.L–1 (48 horas) para machos. Efeitos sub-letais também foram avaliados expondo fêmeas por 24 horas a uma concentração equivalente a CL10. As fêmeas apresentaram uma redução significante na produção de ovos e pelotas fecais, assim como um retardo na eclosão dos ovos. Desta forma, os efeitos tóxicos da FSA do óleo podem comprometer a manutenção da população da espécie no meio ambiente, podendo influenciar o equilíbrio.2012-07-31T18:10:15Z2012-07-31T18:10:15Z2010info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfAVILA, Tatiana Ramos; BERSANO, José Guilherme Filho; FILLMANN, Gilberto.
