Characterizing the Plant Uptake Factor of As,Cd and Pb for Rice and Wheat Cereal
水稻、小麦籽粒砷、镉、铅富集系数分布特征及规律

The statistical characteristics of plant uptake factor(PUF) of As,Cd and Pb for rice/wheat cereal were analyzed and summarized based on collected data in China.The data were selected and distinguished between field investigation and glasshouse experiment in which metal salts were added to clean soils as grown media.Results showed that the PUF median and range of As,Cd and Pb for rice cereal were 0.026(0.004-0.090),0.150(0.014-1.470),0.005(0.001-0.031) and 0.010(0.003-0.033),0.360(0.056-1.700),0.002(0.001-0....
