This book, reveals the mechanism, of the physico-chemical properties, on the translocation of tungsten (W), from soil-vegetables, under agrarian system, in low pH conditions, field studies & quality assurance/agro-environmental concentrations [103]. And the relative error of the recoveries of W were -8.12%, -12.28%, -12.50%, -6.25%, -9.37%, -11.67%,-17.91%,-16.66%,(single extraction), for the determinants. Furthermore, PCA analysis, is a simple correlation analysis, the data's have been grouped in cluster as contrast to the latter, the closer the distance to FW edible vegetable parts, the most significantly the relationship "e.g FW vegetable edible parts vs Available fraction (p ¿ 0.05), n=113), indicating that the higher the AF, the greater the uptake of W by the Vegetables from the soil. The pRBC values reveal no possible risk to children, whereas the EDI values may indicate health risks exposure, the bio-kinetic model for W-exchange of compartments fluid.The abdominal absorption of W through foods, may reveal new insights in an inverse geometry increase over time (¿5 years).
