AbstractThe bioorganic carbon contents and chemical element compositions in six kinds of cereals: paddy (rice), wheat (flour), soybean, millet, sorghum and corn were determined by X-ray fluorescence (XRF) spectrum, meanwhile a new method was established to probe their protein contents. In the cereals, the average bioorganic carbon content is about 44%. The highest protein content is 42. 74% from soybean, and other protein content is 28. 56% in millet, 27. 57% in wheat, 24. 99% in corn, 22. 21% in sorghum, but only 20. 31% in rice. Based on our new definition of carbon chemical circulation presented in the current work, the authors have found that in 2009 humankind used bioorganic carbon to discharge CO(2) into the earth's atmosphere that accounts for one percent of the total CO(2) discharge, and consumed organic carbon to release CO(2) into the earth's atmosphere, accounting for 10. 73% of the total CO(2) discharge. The clear definition of carbon chemical circulation and the discharged CO(2) content from the distinct types of carbon compounds would advance the study on carbon chemical circulation and the atmospheric CO(2) greenhouse effect. Our work further found that it takes eight years to circulate the total earth's atmospheric CO(2). The short period shows the sensitivity for CO(2) to keep its dynamical equilibrium in the earth's atmosphere. However, no experimental data has been reported to prove a heavy destructive greenhouse effect of CO(2) existing in the earth's atmosphere.
