Juvenile rockfish Sebastes schlegelii (mean length 10.8±1.4cm, and mean weight 31.7±3.6g) were exposed for 4 weeks with the different levels of dietary chromium (Cr) at 0, 120 and 240mg/L and ascorbic acids (AsA) at 100, 200 and 400mg/L. Significant accumulation occurred in specific tissues and hematological parameters were altered: red blood cell count, hematocrit, and hemoglobin increased; plasma components were altered including calcium, glucose, cholesterol, total protein, glutamic oxalate transaminase, and glutamic pyruvate transaminase. However, magnesium and alkaline phosphatase concentrations were unchanged. Ascorbic acids reduced both chromium uptake into tissues and altered hematological parameters.
将幼年许氏平鲉（平均体长10.8±1.4厘米，平均体重31.7±3.6克）暴露于不同水平的膳食铬（Cr）（0、120和240毫克/升）和抗坏血酸（AsA）（100、200和400毫克/升）中4周。特定组织中出现了显著的积累，血液学参数发生了改变：红细胞计数、血细胞比容和血红蛋白增加；血浆成分发生了改变，包括钙、葡萄糖、胆固醇、总蛋白、谷氨酸草酰乙酸转氨酶和谷氨酸丙酮酸转氨酶。然而，镁和碱性磷酸酶浓度没有变化。抗坏血酸既减少了铬在组织中的摄取，也改变了血液学参数。
