| 中文摘要: |
| 鳄蜥（Shinisaurus crocodilurus）为国家I级保护野生动物。近年来，我国广西大桂山鳄蜥国家级自然保护区北娄繁育基地救护的鳄蜥一直存在疾病困扰，但原因不明。为了探讨这些疾病的发生是否与其食物中的重金属及农药污染相关，本研究采用电感耦合等离子体质谱和色谱质谱分析技术来检测其主要食物中的重金属和农药残留含量。结果显示，与其食物（蚯蚓）相比，鳄蜥体内的重金属含量更低，同时，农药残留含量在鳄蜥及其食物中均未检测出，说明重金属和农药通过食物的生物放大作用而在鳄蜥体内累积的可能性较小。因此，重金属与农药这两类环境污染物对鳄蜥疾病发生的影响较小。本研究为鳄蜥的人工救护繁育工作提供一定的参考，有利于鳄蜥的保护工作。 |
| 英文摘要: |
| The Crocodile Lizard (Shinisaurus crocodilurus) is the first-class protected wild animal. In recent years, crocodile lizards in the Beilou Station in Guangxi Daguishan Crocodile Lizard National Nature Reserve in China have been plagued by diseases, but the reasons are unknown. To investigate whether the occurrence of these diseases was related to the pollution of heavy metals and pesticides in food, this study detected heavy metals and pesticide residues in their main food using inductively coupled plasma mass spectrometry and chromatography mass spectrometry. Results showed that heavy metals were lower in the crocodile lizards compared with their food (earthworms), while pesticide residues were not detected in crocodile lizards and their food. These results indicate that it is less likely that heavy metals and pesticides accumulate in the crocodile lizards through biomagnification. Therefore, environmental pollutants such as heavy metals and pesticides have little effect on the occurrence of crocodile lizard disease. This study provides a references for the artificial rescue and breeding of crocodile lizards, which is benefit to the protection Crocodile Lizards. |
