This paper reviewed the Se in the environment (including total Se in soil, water, plants, and food), the daily Se intake and Se content in human hair were also examined to elucidate Se distribution in the environment and its effects on human health in China. Approximately 51% of China is Se deficiency in soil, compared with 72% in the survey conducted in 1989. Low Se concentrations in soil, water, plants, human diet and thus human hair were found in most areas of China. The only significant difference was observed between Se-rich and Se-excessive areas for Se contents in water, staple cereal, vegetables, fruits, and animal-based food, no remarkable contrast was found among other areas (p>0.05). This study also demonstrated that 39-61% of Chinese residents have lower daily Se intakes according to WHO/FAO recommended value (26-34μg/day). Further studies should focus on thoroughly understanding the concentration, speciation, and distribution of Se in the environment and food chain to successfully utilize Se resources, remediate Se deficiency, and assess the Se states and eco-effects on human health.
本文综述了中国环境中的硒（包括土壤、水、植物和食物中的总硒），以及人体头发中的日常硒摄入量和硒含量，以阐明硒在中国环境中的分布及其对人类健康的影响。与 1989 年的调查相比，中国约有 51%的土壤缺硒。在中国的大部分地区，土壤、水、植物、人类饮食以及因此人类头发中的硒浓度都较低。只有在富硒和硒过量地区的水中、主食谷物、蔬菜、水果和动物源性食物中的硒含量存在显著差异，而其他地区之间没有明显差异（p＞0.05）。本研究还表明，根据世界卫生组织/粮农组织推荐值（26-34μg/天），39-61%的中国居民硒摄入量较低。进一步的研究应集中于深入了解环境和食物链中硒的浓度、形态和分布，以成功利用硒资源、纠正硒缺乏、评估硒状态以及对人类健康的生态影响。
