Abstract
Damage to the kidneys and gills of the three spined stickleback Gasterosteus aculeatus have been investigated, using light microscopy after exposure of fish to 2 to 6 mg Cd2+ liter-1 hard water (299 mg liter-1 as CaCO3). Cytological breakdown of kidneys and gill tissue appears to be the cause of death, since oxygen uptake and cadmium excretion are impaired, leading to tissue hypoxia and fish poisoning.
摘要
在将三刺鱼（Gasterosteus aculeatus）暴露于2至6毫克/升Cd2+的硬水（以碳酸钙计为299毫克/升）中后，利用光学显微镜对其肾脏和鳃的损伤进行了研究。肾脏和鳃组织的细胞学破坏似乎是死亡原因，因为氧气摄取和镉排泄受损，导致组织缺氧和鱼类中毒。
