Aluminum is liberated from aluminosilicates of soil clays and protracted Al intake by humans in food and medications has been shown to be a potential hazard to human health. Encephalopathology, senility, and lower statistical longevity were found to be geographically and geochemically linked to acid soil conditions. We examined the interrelation of soil environmental supply of Al3+(6H2O) to the food-plant-animal-human chain (e.g., in tea leaves, approximately 1000 mg L-1) and to identified health hazards. Because F forms a strong ligand with Al, we also analyzed the extent that F accumulation is associated with Al accumulation in plants such as tea. Food and medicinal intake of Al needs to be considered in relation to kidney weakness and Al accumulation in humans. Acid soil and plant management could be modified to reduce the hazard of Al in senile dementia (2 to 4 percent of persons age greater than 65 years) and in diseases of the central nervous system endemic in certain acid soil areas.
铝从土壤黏土的铝硅酸盐中释放出来，人类通过食物和药物长期摄入铝已被证明对人体健康存在潜在危害。人们发现，脑病理学、衰老以及较低的统计寿命在地理和地球化学上与酸性土壤条件有关。我们研究了土壤环境中Al3+(6H2O)对食物链（从食物植物到动物再到人类，例如茶叶中约含1000毫克/升）的供应情况以及已确定的健康危害之间的相互关系。由于氟与铝形成强配体，我们还分析了氟在茶叶等植物中的积累程度与铝积累的关联。需要结合人体肾脏虚弱和铝积累情况来考虑铝的食物和药物摄入量。可以调整酸性土壤和植物管理方式，以降低老年痴呆症（65岁以上人群中2%至4%的人患病）以及某些酸性土壤地区地方性中枢神经系统疾病中铝的危害。
