将鲤(6月龄)饲养在Cr6+浓度系列:0、0.12、0.67、1.22、3.661、0.97和32.91mg.L-1的水体中40d,T0.12~T3.66组的绝对增重率和绝对增长率较对照鱼有增重的趋势;铬对鲤血清渗透压和血清离子的影响:自染毒T0.67组引起血清渗透压升高,血清Na+和Ca2+浓度较对照鱼也有明显提高;血清K+浓度有升高的趋势,仅T10.97组有显著差异;个别染毒组Mg2+浓度降低;铬对多数染毒鱼的Cl-浓度影响不明显。铬对血清激素水平影响:T3.66组的T3含量、T10.93组的T4含量以及T0.67组以上的高剂量染毒组的皮质醇含量均较对照鱼明显升高。多数铬处理组鲤肌肉的粗蛋白和粗脂肪含量较对照鱼降低。鱼体铬蓄积量大小依次为:肌肉<鳃<肝<肠。肌肉中铬含量超标(3.00mg.kg-1)为T32.91组鱼,肠中铬超标(2.24mg.kg-1)为T0.67组鱼。 Carp (6 months old) were kept in the Cr6 + concentration series: 0,0.12,0.67,1.22,3.661,0.97 and 32.91mg.L-1 of the water 40d, T0.12 ~ T3.66 group, the absolute weight gain and The absolute growth rate had a tendency to increase weight compared with that of the control fish. The effect of chromium on the serum osmolality and serum ion of carp: The serum osmotic pressure increased from T0.67 group and the serum Na + and Ca2 + Serum K + concentration tended to increase. Only T10.97 group had significant difference. The concentration of Mg2 + in individual exposure groups decreased. The effect of chromium on Cl- concentration of most of the exposed fish was not obvious. The effect of chromium on serum hormone levels: T3 content of T3.66 group, T4 content of T10.93 group and cortisol content of T0.67 group were significantly higher than that of control fish. The crude protein and crude fat content of carp muscle in most chrome treatment groups was lower than that in control fish. Chromium volume of fish body size were as follows: muscle
