The content of macro-and trace elements in honeybee pollen loads collected from the Al-Ahsa oasis, Saudi Arabia during spring, summer, autumn, and winter in 2018/2019 were determined. After critical screening and observation, we found that the major pollen floral resources were rapeseed, sunflower, summer squash, and date palm. The highest values of sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), phosphorus (P) and manganese (Mn) were found in pollen loads trapped during spring and winter. The highest levels of copper (Cu) and iron (Fe) were found from pollen loads harvested during autumn, while the highest content of zinc (Zn) was found in pollen loads collected during the summer. Higher concentrations of the essential elements (Na, K, Ca, Mg and P) for human nutrition found in pollen loads collected during the spring and winter seasons, make them valuable food supplements. Finally, the elements contained in pollen loads can be related to the season of pollen load collection.
对2018/2019年春、夏、秋、冬四季从沙特阿拉伯艾哈萨绿洲采集的蜜蜂花粉负载中的常量和微量元素含量进行了测定。经过严格筛选和观察，我们发现主要的花粉植物资源是油菜籽、向日葵、西葫芦和枣椰树。春季和冬季捕获的花粉负载中钠（Na）、钾（K）、钙（Ca）、镁（Mg）、磷（P）和锰（Mn）的含量最高。秋季收获的花粉负载中铜（Cu）和铁（Fe）含量最高，而夏季采集的花粉负载中锌（Zn）含量最高。在春季和冬季采集的花粉负载中发现了较高浓度的人体营养必需元素（Na、K、Ca、Mg和P），这使它们成为有价值的食物补充剂。最后，花粉负载中所含元素可能与花粉负载的采集季节有关。
