蜜蜂和其他授粉者数量减少的原因仍然是一个持续的争论。虽然最近的注意力集中在农药上，但其他环境污染物在很大程度上被忽视了。铝是近年来最重要的环境污染物，我们推测它可能是传粉媒介减少的一个因素。在这里，我们已经测量了在英国的自然觅食殖民地的熊蜂蛹中铝的含量。在微波炉中酸消化单个腐殖酸，并使用横向加热石墨炉原子吸收光谱法测定其铝含量。腐殖酸被铝严重污染，其值在13.4至193.4微克/克干重之间。平均值（SD）为51.0（33.0）μg/g干重。测试的72名患者。平均铝含量被证明是一个显着的负预测平均蛹重的殖民地。虽然没有发现铝与蜜蜂或蜂群健康之间的其他统计学显著关系，但蛹中铝的实际含量极高，表明铝的显著暴露。蜜蜂在很大程度上依赖于认知功能，铝是一种已知的神经毒素，与人类的阿尔茨海默病有关。铝对大黄蜂蛹的严重污染引发了一个有趣的幽灵，即认知功能障碍在它们的数量下降中发挥了作用。
The causes of declines in bees and other pollinators remains an on-going debate. While recent attention has focussed upon pesticides, other environmental pollutants have largely been ignored. Aluminium is the most significant environmental contaminant of recent times and we speculated that it could be a factor in pollinator decline. Herein we have measured the content of aluminium in bumblebee pupae taken from naturally foraging colonies in the UK. Individual pupae were acid-digested in a microwave oven and their aluminium content determined using transversely heated graphite furnace atomic absorption spectrometry. Pupae were heavily contaminated with aluminium giving values between 13.4 and 193.4 μg/g dry wt. and a mean (SD) value of 51.0 (33.0) μg/g dry wt. for the 72 pupae tested. Mean aluminium content was shown to be a significant negative predictor of average pupal weight in colonies. While no other statistically significant relationships were found relating aluminium to bee or colony health, the actual content of aluminium in pupae are extremely high and demonstrate significant exposure to aluminium. Bees rely heavily on cognitive function and aluminium is a known neurotoxin with links, for example, to Alzheimer’s disease in humans. The significant contamination of bumblebee pupae by aluminium raises the intriguing spectre of cognitive dysfunction playing a role in their population decline.
