Study on the Safety of Three Edible Wild Herbs

[目的]探讨3种特色野菜的食用安全性,为消费者食用野菜提供理论支持。[方法]测定了菜芙蓉、水芹菜和婆罗门参3种特色野菜的硝酸盐、亚硝酸盐、重金属含量和小鼠最大耐受量,并对其进行了健康风险和毒性风险评价。[结果]3种野菜硝酸盐和重金属含量都较低,污染程度都在安全级以内,日常食用不会对居民健康造成风险;小鼠给予60.0 g/(kg·d)的剂量(相当于成人每天3.6 kg食用量),未出现急性中毒反应和病理变化。[结论]菜芙蓉、水芹菜和婆罗门参3种野菜日常适量食用是安全的。

[ Objective ] The aim was to discuss the safety of three edible wild herbs,to provide theoretical support for people consumption of edi- ble wild herbs. [ Method ] The content of nitrate, nitrite and heavy metal in Abelmoschus manihot （ L. ） Medic, Oenanthe javanica and Tragopogon porrifolius L. were measured.
