| Abstract: | The effects of low PH value and with or without the addition of aluminum on the uptake of 45Ca by Misgurnus anguillicaudatus were studied. The results showed that the speific activities of 45Ca are 39 532 cpm/g in skin,38 116 cpal/g in skeleton, 25 495 cpm/g in gill and 1 651cpm/g in muscle resistively after exposed to PH 7.10(control) for 96 h, Compared with the control, the specaac activities of 45Ca decline about 81.07% in skin,84.41% in skeleton 0.11% in gill and 5.88% in muscle after exposed to PH 4.70 without aluminum. Under the condition of PH 4.70 with the eddition of aluminum (1.0 mp/L),the speific activities of 45Ca decline.about 89.87% in skin, 88.83% in skeleton. 86.17% in gill and 26.47% in muscle respectively.The effects of acid the on the calcium metabolism in fish were discussed. |
