海水中油污染对海胆的急性毒性研究
cute Toxicity of Oil Pollution on sea urchin
溢油事故不断增加对海洋生物的危害日益增大。目前海胆(sea urchin)受海洋油污染所表现的性状方面的研究国内外均未见报到。通过轻质原油和重柴油不同加油量对海胆进行96h急性毒性对比实验，研究表明，在本实验条件下，轻质原油加油量为35ml以上，24h内海胆全部死亡；轻质原油加油量为25ml以上和重柴油加油量达到35ml以上时，48h内海胆全部死亡现象。但轻质原油和重柴油加油量为15ml时，96h后海胆全部死亡。由此可见，海胆对海水中油污染具有一定的抗性，同时轻质原油比重柴油污染对海胆的急性毒性大。
ccidents of oil Spill harm to the marine life increasingly. The study has not been reported about acute toxicity of oil pollution on sea urchin. According to acute toxicity experimental in 96h result of the light crude oil and the heavy diesel in different adding quantity on sea urchin, sea urchin all dead in 24h up 35ml adding quantity of light crude oil ; sea urchin all dead in 48h up 25ml adding quantity of light crude oil and 35ml adding quantity of the heavy diesel. But sea urchin all dead in 96h when the adding quantity of the light crude oil and the heavy diesel were 35ml . So, sea urchin have a little repellence to oil pollution in the sea water. At the same time, acute toxicity of the light crude oil more than the heavy diesel on sea urchin.
