在实验室条件下研究了4种多环芳烃(菲、三甲基菲、蒽和二甲基蒽)对海胆(Strongylocentrotus intermendius)的耗氧率和排氨率及氧氮比(O∶N)的影响。结果显示:(1)海胆耗氧率在10、20、50、100和150μg/L菲、三甲基菲、蒽和二甲基蒽的作用下显著低于对照组,说明这4种多环芳烃在实验浓度条件下对海胆的呼吸耗氧率产生了显著的影响(P<0.05);(2)海胆的排氨率随着四种多环芳烃浓度的升高而升高,呈现出一定的剂量-效应关系。(3)海胆的O∶N比随着4种多环芳烃浓度的升高而下降,并在一定浓度(10~50μg/L)条件下达到稳定。
The oxygen consumption rate, ammonia excretion rate and oxygen to nitrogen ratio (O: N) of four kinds of PAHs (phenanthrene, trimethylphenanthrene, anthracene and dimethylanthracene) to Strongylocentrotus intermendius were studied under laboratory conditions. Impact. The results showed that: (1) The oxygen consumption rate of sea urchin was significantly lower than that of the control group under the effects of 10, 20, 50, 100 and 150 μg / L phenanthrene, trimethylphenanthrene, anthracene and dimethylanthracene, The aromatics had a significant effect on the respiratory oxygen consumption of sea urchin under the experimental conditions (P <0.05). (2) The ammonia excretion rate of sea urchin increased with the increase of four PAHs, Dose-response relationship. (3) The ratio of O: N of sea urchins decreased with the concentration of four PAHs and reached a certain level (10-50 μg / L).
