目的:对福建泉州短葶山麦冬种植基地土壤、灌溉用水及其药材中的有机氯农药与重金属残留量进行分析评价,为山麦冬安全规范化生产提供参考依据。方法:采用GC法测定有机氯农药残留量,用ICP法测定铅(Pb)、镉(Cd)、铜(Cu)、铬(Cr)、砷(As)含量。结果:泉州短葶山麦冬种植土壤、灌溉用水和药材中的有机氯农药与重金属残留存在一些差异,但均低于国家限量标准。结论:泉州短葶山麦冬种植基地土壤、灌溉用水和药材符合中药材GAP标准。
OBJECTIVE: To analyze and evaluate the organochlorine pesticides and heavy metal residues in the soil, irrigation water and their medicinal materials in the Ophiopogon japonicus planting site in Short Jujiu Mountain, Quanzhou, Fujian Province, and to provide references for the safe and standardized production of Ophiopogon japonicus. Methods: The content of organochlorine pesticide residues was determined by GC method. The contents of lead, cadmium, copper, chromium and arsenic were determined by ICP. Results: There were some differences in the organochlorine pesticides and heavy metal residues in the soil, irrigation water and medicinal herbs planted on the Ophiopogon japonicus in Quanzhou, but both were lower than the national limit standards. Conclusion: The soil, irrigation water and medicinal materials of Radix Ophiopogon japonicus in Quanzhou are in conformity with GAP standard.
