| Abstract: |
| In this study, we investigated the effects of carbon nanomaterials on Festuca arundinacea growth, antioxidant enzyme activities, and malondialdehyde content in Eisenia foetida by adding three types of carbon nanomaterials[graphene (G), graphene oxide (GO), and carbon nanotube (CNT)] to the turf media in different ratios (1% and 3%). Exposure to the carbon nanomaterials lasted for 90 days. We found no significant differences in plant height and shoot weights of Festuca arundinacea in the treatments with 1% and 3% of carbon nanomaterials. When earthworms were exposed to 1% and 3% of carbon nanomaterials, their superoxide dismutase (SOD) activity decreased significantly, with an inhibition rate of 39.3% in the treatment with 3% CNT. Peroxidase (POD) activity in Eisenia foetida decreased significantly, with an inhibition rate of 37.6% in the 3% GO treatment. Catalase (CAT) activity in Eisenia foetida increased in the 1% GO treatment, but decreased in treatments with 3% GNT and 3% G. In addition, we found no significant differences in Glutathione S-Transferase (GST) activity or malondialdehyde (MDA) content in earthworms exposed to carbon nanomaterials. These results suggest that a certain concentration of carbon nanomaterials will not affect turfgrass growth but can stimulate the production of ROS in earthworms and cause changes in the activities of antioxidant enzymes, indicating that carbon nanomaterials have some toxic effects on earthworms. |
