| Abstract: |
| This study provides an important scientific basis for the effectiveness of Ethanamizuril, EZL in evaluating environmental safety. The efficiency of EZL in different soils was studied through incubation experiments. The effects of EZL on the respiration of the soil microbial community and its acute toxicity to earthworms were also studied. The results showed that EZL was biodegradable, and its degradation rate decreased with an increase of culture time and EZL concentration. Its moderate toxicity on the respiration rate of soil microorganisms was comparatively studied, and it was noticed that microorganisms from Nanjing yellow-brown soils were affected to some extent, but microbes from Shanghai calcareous alluvial soils were unaffected. The artificial soil test showed that EZL caused low toxicity to the earthworm at 14 d-LC50 in 9 255.90 mg·kg-1 of dry soil. EZL is a new veterinary drug, which is relatively safe and degrades easily. |
