The latest evaluation of atomic weight determinations and other cognate data has warranted 16 changes for the standard atomic weights of the elements, Ar(E), from those published previously in the 2001 Table of Atomic Weights. The revised standard atomic weights are as follows: Ar(Al) = 26.981 5386(8), Ar(Bi) = 208.980 40(1), Ar(Cs) = 132.905 4519(2), Ar(Co) = 58.933 195(5), Ar(Au) = 196.966 569(4), Ar(La) = 138.905 47(7), Ar(Mn) = 54.938 045(5), Ar(Nd) = 144.242(3), Ar(P) = 30.973 762(2), Ar(Pt) = 195.084(9), Ar(Sm) = 150.36(2), Ar(Sc) = 44.955 912(6), Ar(Na) = 22.989 769 28(2), Ar(Ta) = 180.947 88(2), Ar(Tb) = 158.925 35(2), Ar(Th) = 232.038 06(2). A recommendation is made that δ13C values of all carbon-bearing materials be measured and expressed relative to Vienna Pee Dee Belemnite (VPDB) on a scale normalized by assigning consensus values of -46.6 ‰ to L-SVEC lithium carbonate and +1.95 ‰ to NBS 19 calcium carbonate.
