| 中文摘要: |
| 为了评价沙咪珠利对环境的初步影响，采用室内培养法研究三种不同土壤中沙咪珠利的降解作用，同时探究沙咪珠利对土壤微生物呼吸强度的影响，及对蚯蚓的急性毒性。结果表明，沙咪珠利易降解，降解速率随培养时间的延长和添加浓度的增加而降低。土壤中沙咪珠利的残留可影响土壤微生物呼吸，对南京地区黄棕壤中的微生物有中等毒性，对上海地区灰潮土中的土壤微生物作用不明显。人工土壤法测得沙咪珠利对蚯蚓LC50（14 d）为9 255.90 mg·kg-1，毒性较低。研究表明，沙咪珠利是一种相对安全、易于降解的新型兽药。 |
| 英文摘要: |
| 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. |
