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展开更多

The data regarding effect of ozone depletion on human was reviewed and compiled as a review paper from various published articles of international reputed journals, annual/environmental reports of recognized organization and e-books. The causes, mechanism and bio-effects of ozone layer depletion on humans were addressed. It is revealed that introduction of Chloroflourocarbons (CFCs) in the environment is the most rated cause of said depiction. Ozone depletion is allowing the UV radiation to earth surface. The exposure to these radiations is severely affecting all life forms on earth, especially the humans. Permanent or temporary blindness, skin cancer and immunity suppression are the main effects of these radiations reported by various researchers on humans. The prospects of ozone recovery are still undiscovered. The current situation of ozone depiction demands urgent remedial measures to protect lives on this earth.展开更多

After 72 h, EROD activities in livers of the test organisms were measured. It was found that EROD activities significantly mounted up with the increase of spiked quantity. Therefore, there existed a dose-response relationship between EROD activities and specific pollutant concentrations. In the meantime, the optimal conditions for the analysis of EROD activity were discussed. The limitation of EROD activities as a monitoring parameter was also analyzed.展开更多

The results indicated that infection rate decreased and there were significant disease controlling effects on seed rot, bud rot and root rot caused by pathogenic fungi when the seeds were soaked by La^3＋. Thus, the rates of emergence of Isatis indigotica Fort. and turfgrass Festuca arundinacea were increased, When La^3＋ concentration was in a proper range, the growth and development of plant seed/ings were promoted. Spraying La on rice plants showed a significant controling effect on Rhizoctonia solani. Furthermore, the EC50 of La^3＋performed 128.7 and 128.1 mg/L at 1 and 7 d after spraying La in rice plants, respectively. The EC50 of La^3＋ performed in vivo （in rice plant） was lower than that in vitro （171.9 mg/L）.展开更多
