    摘要:

    为测定松花粉中18种无机元素的含量,并对重金属及有害元素进行安全性和健康风险评估,采用微波消解法处理样品,利用电感耦合等离子体质谱法(ICP-MS法)进行测定,使用软件Origin 2021和微生信平台绘制松花粉无机元素特征谱图和相关系数矩阵图,通过计算重金属元素的单项污染指数Pi对松花粉的安全性进行评估,计算重金属元素的每日最大可耐受量、靶标危害系数和致癌风险,并对松花粉的健康风险进行评估。结果表明:松花粉中主要含有Na、Mg、K、Ca、Fe、Zn 6种无机元素;Pi结果显示松花粉样品未被污染,水平优良;松花粉样品中重金属及有害元素未对暴露人群产生健康风险。采用ICP-MS法对松花粉中18种无机元素进行测定分析,可为松花粉的质量安全评价和推广应用提供一定的理论依据。

    Abstract:

    In order to determine the content of 18 inorganic elements in pine pollen and evaluate the safety and health risks of heavy metals and harmful elements, the samples were treated by microwave digestion method, and then determined by ICP-MS method. The characteristic spectra and correlation coefficient matrix of inorganic elements in pine pollen were drawn by Origin 2021 and Micro-Signal platform. The safety of pine pollen was evaluated by calculating the single pollution index Pi of heavy metal elements. The daily maximum tolerable dose, target hazard quotient and carcinogenic risk of heavy metal elements were calculated to evaluate the health risk of pine pollen. The results show that pine pollen mainly contains six inorganic elements: Na, Mg, K, Ca, Fe and Zn. The results of Pi show that the pine pollen samples are not contaminated and the level is excellent. The heavy metals and harmful elements in pine pollen samples do not pose health risks to the exposed population. The determination and analysis of 18 inorganic elements in pine pollen by ICP-MS method provides a theoretical basis for the quality and safety evaluation and further application of pine pollen.
