| 摘 要： | 以黄河兰州段11个不同采样点3种多环芳烃的临测浓度及其对6～38种水生生物的LC50为基础资料,分别应用商值法、概率密度函数重叠面积和联合概率曲线3种风险浮价方法对黄河兰州段苯并(a)芘、荧蒽、芘的生态风险进行了评价.结果表明:黄河兰州段3种PAHs残留具有一定的生态风险.其中低暴露风险条件下(受威胁生物不超过1%),...

| Abstract: | Based on the observed concentrations of Polycyclic Aromatic Hydrocarbons in 11 surface water samples from the Lanzhou reach of the Yellow River and LC50 values of 6~38 of aquatic organisms,the quotient method and two probabilistic risk approaches were applied to characterize the ecological risks of benzo[a]pyrene,fluoranthene,and pyrene in water from the Lanzhou reach of the Yellow River.The results indicated that three residual PAHs have some ecological risk.While at the lower exposure level(percent of spe... |
