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

    Graphical Abstract
    • 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.
