【摘要】：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(P0.05);(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。
[Abstract]:The effects of four polycyclic aromatic hydrocarbons (phenanthrene, trimethylphenanthrene, anthracene and dimethylanthracene) on the oxygen consumption rate, ammonia excretion rate and oxygen nitrogen ratio (O N) of sea urchin (Strongylocentrotus intermendius) were studied in laboratory. The results showed that: (1) the oxygen consumption rate of sea urchin at 10,20,50100 and 150 渭 g / L phenanthrene, trimethylphenanthrene, anthracene and dimethylanthracene was significantly lower than that of the control group. The results showed that these four polycyclic aromatic hydrocarbons had a significant effect on respiratory oxygen consumption rate of sea urchins at experimental concentration (P0.05). (2) the ammonia excretion rate of sea urchins increased with the increase of the concentrations of four polycyclic aromatic hydrocarbons, showing a dose-effect relationship. (3) the O / N ratio of sea urchins decreased with the increase of the concentrations of four kinds of polycyclic aromatic hydrocarbons. It is stable at a certain concentration (10 ~ 50 渭 g / L).
