A 3-month microcosm study was conducted to observe the potential effects of two fuels, Orimulsion and Fuel Oil #6, on the hatching success of copepod resting eggs in the seabed of Tampa Bay, Florida. Microcosms were dosed with one of five hydrocarbon treatments via hydrocarbon-coated sand and compared with controls. Acartia tonsa eggs were nonviable in all treatments after only a few weeks of incubation, as evidenced by a marked decline in the abundance of nauplii. However, there was no evidence that exposure to simulated spills of 700 or 7000 ppm of either fuel led to significant increases in resting egg mortality as compared with controls. The results further indicate that, regardless of environmental conditions, resting eggs of A. tonsa do not remain viable in the sediment for extended periods of time.
进行了一项为期3个月的微观世界研究，以观察两种燃料（奥里乳化油和6号燃料油）对佛罗里达州坦帕湾海床中桡足类休眠卵孵化成功率的潜在影响。通过涂有碳氢化合物的沙子，对微观世界进行五种碳氢化合物处理之一的加药，并与对照进行比较。仅仅孵化几周后，在所有处理中，中华哲水蚤的卵均无活力，无节幼体数量显著下降证明了这一点。然而，没有证据表明，与对照相比，暴露于700或7000 ppm任何一种燃料的模拟泄漏中会导致休眠卵死亡率显著增加。结果还进一步表明，无论环境条件如何，中华哲水蚤的休眠卵在沉积物中都不会长时间保持活力。
