水蛭及其养殖基地农药与重金属残留分析

Residues analysis of pesticides and heavy metals in Whitmania pigra and its breeding base

目的:通过对水蛭药材、养殖基地土壤、养殖用水的重金属与农药残留的比较研究,为水蛭的安全规范化生产提供依据和实践。方法:采用等离子发射光谱仪、原子荧光分光光度计和气相色谱仪对水蛭、基地土壤和养殖用水的重金属与农药残留进行了比较分析。结果与结论:除水蛭药材中铅超出国家现行有关标准外,水蛭药材,养殖基地土壤和养殖用水的六六六、DDT和重金属残留各项指标均符合国家标准规定。建议今后在制订国家有关标准时将类似水蛭类等动物的安全限量单独列出。

Objective： To give a reference to the safe and standardized production of Whitmania pigra, through the comparative research on residues of heavy metals and pesticide in W. pigra, breeding base soil and breeding water . Method： Residues of heavy metals and pesticide in W. Pigra , soil and water were determined by atomic absorption spectrophotometers, atomic fluorescence spectrophotometers and GC-ECD. Result and Conclusion： With the exclusion of Pb residue, the residues of HCH, DDT and other heavy metals in W. pigra, soil and water in breding base met the requirements of the national standards. We suggest that the residues limits of animal drugs like W. pigra should be listed in a separate category when the national standards are revised in the fature.
