| 中文摘要 | The effects of cadmium and the polycyclic aromatic hydrocarbon (PAH) pyrene on the earthworm Eisenia fetida were investigated in contact and soil tests. Metabolic (glutathione-S-transferase, GST) and oxidative (catalase, CAT) stress enzymes were studied as biomarkers in earthworms after 48 hours, 14 days and 28 days. Contact test indicated that cadmium had significant effects on survival and enzyme activities while pyrene influenced neither in the studied concentrations. Induction of CAT and GST in earthworms exposed to cadmium and pyrene in the acute soil test (14 d) revealed the metabolism of these chemicals resulting in the production of reactive oxygen species. After a relatively long period of exposure ( 28 d), earthworms exposed to pyrene failed to handle the high toxicity and were physiologically damaged, while those exposed to cadmium adapted to the disturbed environment through effective metabolism of the chemical and management of the oxidative stress. |
