Abstract选择贵州万山汞矿区及雷山参考点,采集了7属9种陆生常见节肢动物,分析了其体内的汞、硒和delta~(13)C、delta~(15)N含量特征,探讨了联合暴露下硒、汞在陆生食物链的传递规律。结果表明: 参考点节肢动物体内汞、硒平均含量分别为157329和190277 ng·g~(-1),显著低于汞矿区汞、硒的平均含量56921472和2220691 ng·g~(-1); 无论是汞矿区还是对照区,肉食性动物体内汞含量显著高于植食性动物,表现出显著的生物积累与放大效应; 而硒在肉食性与植食性动物之间没有显著差异,表明硒在节肢动物体内不具有生物积累放大效应。在自然背景条件下,节肢动物体内硒含量与汞含量呈显著正相关(r = 0.983,P<0.001),硒、汞摩尔比接近2 ∶ 1,同时节肢动物体内汞含量与delta~(15)N含量呈正相关(r = 0.434,P<0.001),而与 delta~(13)C关系不明显,表明动物体内delta~(15)N较delta~(13)C更能反映捕食与被捕食营养关系。
