硒是一种天然微量元素，对人类健康至关重要。土壤和粮食作物中硒含量的极大地域差异已导致与环境中硒缺乏或过量相关的重大健康问题。为了在未来应对这类问题，更好地理解控制硒全球分布的过程至关重要。分析技术和方法的最新发展使得能够精确测量环境中的硒含量，这将有助于更好地理解生物地球化学过程。这种更好的理解可能使我们能够预测目前未知地区的硒分布。在一个日益受到人类活动影响的世界里，这些预测对于预防未来的硒健康危害至关重要。
Selenium is a natural trace element that is of fundamental importance to human health. The extreme geographical variation in selenium concentrations in soils and food crops has resulted in significant health problems related to deficient or excess levels of selenium in the environment. To deal with these kinds of problems in the future it is essential to get a better understanding of the processes that control the global distribution of selenium. The recent development of analytical techniques and methods enables accurate selenium measurements of environmental concentrations, which will lead to a better understanding of biogeochemical processes. This improved understanding may enable us to predict the distribution of selenium in areas where this is currently unknown. These predictions are essential to prevent future Se health hazards in a world that is increasingly affected by human activities.
