TOXICTY OF HEAVY METALS IN RIVER SEDIMENTS TO AQUATIC ORGANISMS Ⅰ. TOXICTY OF VARIOUS FORMS OF LEAD TO FISHES

    摘要
  • 摘要: 本文报道了模拟江河底泥中的铅对鲫鱼、鲤鱼等的生物效应,从生物富集、生物化学、超微结构、组织病理、血相等方面研究了底泥铅的不同化学形态的生物学效应。实验结果表明,当底泥中“亲和态”铅为95.23mg/kg时,染毒20-50d,相继发生一系列病理变化,随着实验浓度的增加,时间的延长,病变就愈加严重;底泥铅的“亲和态”浓度与生物效应关系呈正相关。

     

    Abstract: The toxicity of sedimental lead to common carp(Cyprinus carpio), Crucian carp (Carassius auratus) and other fishes was studied in an artificial stream. Investigations were made on the biological accumulation, biochemistry, ultramicroscopic structure, tissue pathology and blood assays of the fishes, fish exhibited a series of pathological changes after 20-50 days exposure to the affinited form of lead at 95.23mg/kg. The pathological effects were positively correlated with the concentration of affinited lead.
