This paper aims to compare the Cd, Cu, and Pb concentration in the bone, gills, and muscle of the seven fish species sampled during normal and dry seasons. Cadmium, Cu, and Pb concentrations varied significantly depending on the type of the tissue and season. Bone samples of the Osteochilus hasseltii showed the highest concentrations of Pb (6.08 μg/g dw) during September (the dry season), whereas bone samples of the Puntioplites bulu showed the lowest concentrations of Cd (0.08 μg/g dw) during September. Muscle samples of the P. bulu indicated the highest concentrations of Cu (2.58 μg/g dw) during March (the normal season). On the other hand, muscle samples of Channa straitus sowed the lowest concentrations of Cd (0.04 μg/g dw) during July (the dry season). Gills samples of the O. hasseltii showed the highest concentration of Pb (6.56 μg/g dw) during March (the normal season), while gills samples of C. straitus indicated the lowest concentration of Cd (0.06 μg/g dw) during July (the dry season).
本论文旨在比较正常季节和干旱季节采集的七种鱼类的骨骼、鳃和肌肉中的 Cd、Cu 和 Pb 浓度。Cd、Cu 和 Pb 的浓度因组织类型和季节的不同而有显著差异。九龙江光唇鱼的骨骼样本在 9 月（干旱季节）表现出最高的 Pb 浓度（6.08μg/g dw），而布氏鲷的骨骼样本在 9 月表现出最低的 Cd 浓度（0.08μg/g dw）。布氏鲷的肌肉样本在 3 月（正常季节）表现出最高的 Cu 浓度（2.58μg/g dw）。另一方面，七带石斑鱼的肌肉样本在 7 月（干旱季节）表现出最低的 Cd 浓度（0.04μg/g dw）。九龙江光唇鱼的鳃样本在 3 月（正常季节）表现出最高的 Pb 浓度（6.56μg/g dw），而七带石斑鱼的鳃样本在 7 月（干旱季节）表现出最低的 Cd 浓度（0.06μg/g dw）。
