There are a few reports on the effects of the complexing agents, as heavy metal pollution-inhibiting agents, to the aquatic animals. SPRAGUE(1968) reported on the influence of NTA on the zinc-and copper poisoning to brook trout. NISHIKAWA and TABATA(1969) conducted some experiments on eliminations of the toxicity of waste water from copper mines with EDTA using water fleas and dace. However, this in an area which has not so far as been clarifies in investigations on metal complexan toxicity and accumulation. In the previous paper, the effects of complexans(EDTA,NTA, and DTPA) on the metal-toxicity(Cd,Cu,Zn and Pb) at lethal levels and of complexan(EDTA) on the removing cadmium from the Cd-polluted fish were reported. This reports is examination of influence of complexans (EDTA and DTPA) on the metal toxicity and on the metal accumulation in viscera, gills and other parts of the fish exposing cadmium at low concentrations, long term(3 months). Vertebrae deformed fish induced by cadmium were observed with eye. The vertebrae of the fish were then examined by x-ray photography.
