目的检测野生环境中黄鼠脑组织重金属铅、砷、汞含量。方法解剖分离捕获的哈尔滨道里、香坊2区13～24月龄野生黄鼠大脑组织,将大脑皮层和其他部分分离,应用原子荧光光度计检测大脑皮层组织内铅、砷、汞含量。结果道里区野生黄鼠脑组织中的重金属铅、砷、汞含量分别为(49.4±32.5)、(46.7±28.5)、(4.271±1.786)μg/kg;香坊区野生黄鼠脑组织中重金属铅、砷、汞含量分别为(90.1±45.0)、(23.0±18.0)、(4.740±0.952)μg/kg;2区野生黄鼠脑组织内铅、汞含量差异无统计学意义(P>0.05);与香坊区比较,道里区野生黄鼠脑组织中砷含量较高,差异有统计学意义(P<0.05)。结论哈尔滨地区野生黄鼠脑内可检出重金属铅、砷、汞,其负荷对环境重金属污染具有指示作用。
Objective To detect the levels of lead, arsenic and mercury in brain tissue of wild chrysin in wild environment. Methods The brain tissues of 13 - 24 months old wild squirrels from 13 to 24 months old were collected and dissected. The cerebral cortex and other parts were separated. The contents of lead, arsenic and mercury in cerebral cortex were detected by atomic fluorescence spectrophotometer. Results The content of lead, arsenic and mercury in brain tissue of Daisy rats were (49.4 ± 32.5), (46.7 ± 28.5) and (4.271 ± 1.786) μg / kg, respectively. The contents of heavy metals The content of lead, arsenic and mercury in the two groups were (90.1 ± 45.0), (23.0 ± 18.0) and (4.740 ± 0.952) μg / kg, respectively. There was no significant difference in the contents of lead and mercury ). Compared with Xiangfang District, the content of arsenic in brain tissue of Daisy rats was higher than that of Xiangfang District, the difference was statistically significant (P <0.05). Conclusion Heavy metal lead, arsenic and mercury can be detected in the brains of wild squirrels in Harbin. The load of heavy metals is indicative of heavy metal pollution in the environment.
