Considering the high number of accidents with diesel oil spills occurring in the marine ecosystem, toxicity tests aimed at assessing the effects of this pollutant on biota are necessary and urgent. Thus, the present study aimed to evaluate the toxicity of the soluble fraction of diesel oil (WSD) in the fertilization success of gametes and pluteu larvae of the sea urchin Echinometra lucunter. To do this, gametes and embryos were exposed to concentrations of 0% (control group), 0.5%, 1.5% and 2.5% of WSD. The fertilization success of exposed gametes and embryos were reduced significantly when compared to the control group in all tested concentrations. With this finding, it is evident that diesel oil can be significantly promoted in the early and adult life stages of a particular organism, and a better way of evaluating this toxicity is through the analysis of contaminant effects throughout the reproductive cycle of a species.
鉴于在海洋生态系统中发生的大量柴油泄漏事故，有必要进行旨在评估这种污染物对生物群影响的毒性测试。因此，本研究旨在评估柴油可溶部分（WSD）对海胆 Echinometra lucunter 配子和幼体幼虫受精成功的毒性。为此，将配子和胚胎暴露于 0%（对照组）、0.5%、1.5%和 2.5%的 WSD 浓度下。与对照组相比，所有测试浓度下暴露的配子和胚胎的受精成功率均显著降低。有了这一发现，显然柴油可以在特定生物体的早期和成年期显著促进，而评估这种毒性的更好方法是通过分析整个物种的生殖周期中污染物的影响。
