摘要
人类对有益元素的关注主要是源于人体健康和地方病的研究。随着人们物质生活的提高,对健康的要求日益增加,有益元素的生物地球化学循环逐渐被广泛研究,主要包括钙、铁、锌、硒、锰、硅等。这些元素通过土壤进入食物链,进而影响人类健康,因此,土壤有益元素对人体及其在生态环境中生物地球化学循环过程中的作用已成为近年来国内外环境领域研究的热点。对动植物必需的有益元素钙、铁、锌、硒、碘的研究进展进行了综述,总结得出,土壤中有益元素的研究不仅仅需要关注其在生物地球化学循环中所起的作用,更应当结合土壤中有益元素与其他元素的作用机制来考虑其生物地球化学行为以及其在循环过程中的作用机理。
The studies of beneficial elements are derived from the relation of human health and the occurrence of endemic diseases. The biogeochemical cycle of beneficial elements are widely studied with the improvement of material life of people and growing demand for health, these elements include calcium, iron, zinc, selenium, iodine, etc. These elements can enter the food chain through the soil, thus affect human health. Therefore, the study on roles of beneficial elements in human body and biogeochemical cycle process in the ecological environment has become a hot research of environment in recent years. In this paper, the beneficial elements including calcium, iron, zinc, selenium and iodine were summarized. Our conclusion shows that the research of beneficial elements in soil not only need pay attention to its role in the biogeochemical cycle, but also should be combined with the mechanism of action of beneficial elements in soil and other elements to consider its biogeochemical behavior and its mechanism in the process of circulation.
