摘要

1. 研究了金黄色Oreochromis aureus (Steindachner)暴露于铅和镉两种浓度下24小时和1周，以评估这些污染物对血液学参数的影响。血浆渗透压是最敏感的血液参数，在其他参数改变前受到影响。镉对金黄色葡萄球菌的毒性似乎比铅更大，对血液参数的不利影响比铅更早。在中毒的早期阶段，镉对血红蛋白浓度的影响似乎比铅更明显。镉不会降低红细胞计数，但铅会。

Effects of acute exposure to cadmium (II) chloride and lead (II) chloride on the haematological profile of Oreochromis aureus (Steindachner)

1. Oreochromis aureus (Steindachner) was exposed to two concentrations of lead and cadmium for 24 hr and 1 week to assess the effects of these pollutants on haematological parameters.

2. Plasma osmolality was found to be the most sensitive blood parameter, affected before other parameters changed.

3. Cadmium appears to be more toxic to O. aureus than lead, having an adverse effect on blood parameters earlier than lead.

4. In the earlier stages of toxicity cadmium appears to have a more pronounced effect on haemoglobin concentration than lead.

5. Cadmium does not depress erythrocyte counts but lead does.
