摘      要：IT has become an urgent subject with the wider application of REE to study the effects of REE on environ- ment and human health. Some important REE toxicology data were obtained previously based on acuteand sub-chronic toxicity experiments on animals, but these results are indirect and suspectable becausethe REE compounds used in the experiments are different from those in food chains, and there still existsome uncertainties when the results are extrapolated from animals to human beings. This note focuses thebio-effects of REE on population from two typical REE-high areas in South Jiangxi, China, where theweathering crust-ion adsorbed-type REE ore deposits are widespread, and also on the estimation of dailyREE intake allowance in terms of REE contents and distribution in food chains. 1 Geologic setting and studying
