SELENIUM SPECIATION IN SE-RICH ROCKS AT YUTANGBA

HAN Wen-liang1,2,ZHU Jian-ming1,QIN Hai-bo1,2,LI Lu1,2,LEI Lei1,2,SU Hong-can3(1.Institute of Geochemistry,Chinese Academy of Sciences,Guiyang 550002,China;2.Graduate School of the Chinese Academy of Sciences,Beijing 100039,China;3.Maternity and Child-care Center in Enshi Prefecture,Hubei,Enshi 445000,China)  
Yutangba,where a sudden incidence of human Se poisoning occurred in 1963,was a typical high-Se area in China.The exposed Se-rich rocks of the Maokou and Wujiaping formations were generally considered to be the main source of Se that was enriched in soils of Yutangba and other places in Enshi,but little is known about the Se speciation trends in these rocks.Procedurally defined Se fractions in Se-rich rocks were determined mainly based on the modified sequential extraction protocol as follows: soluble(MQ water),adsorbed [0.1 mol/L K2HPO4+KH2PO4(pH=7.0)],base soluble(organic matter: 0.1 mol/L NaOH),elemental Se(1 mol/L Na2SO3),carbonate and amorphous oxides(15% CH3CO2H),sulfide/selenide(1 mol/L CrCl2+HCl) and residual Se(HNO3+HF+H2O2).Selenium in bulk rock,fraction and its speciation were measured by HG-AFS.The results showed that base soluble,sulfide/selenide and absorbed Se were of predominant form in carbonaceous shale and carbonaceous chert,while base soluble,elemental and sulfide/selenide Se were of dominant form in mudstone.The proportion of soluble Se in mudstone is significantly lower than that in carbonaceous shale and chert,as well as sulfide/selenide Se,while the amount of elemental Se is significantly greater than that in both rocks,indicating the current geochemical weathering condition of Yutangba is favorable for Se mobilization and re-deposition as secondary native Se in suitable positions such as interbedded mudstone layer.Se(IV) is significantly greater in proportion in soluble,absorbed and base soluble Se fraction,rather than organic-Se and Se(VI).This revealed Se(IV) is the predominant speciation for Se transportation and bioavailability,and also affected the total concentration of Se in whole rocks.The results support that Se was highly associated with organic matter.Adsorption of Se(IV) by organic matter and clay in carbonaceous Se-rich rocks plays an important role in the weathering process of Se-rich rocks in Yutangba.
