Mv. Frontasyeva et al., MOSS AS MONITOR OF HEAVY-METAL DEPOSITION - COMPARISON OF DIFFERENT MULTIELEMENT ANALYTICAL TECHNIQUES, Journal of radioanalytical and nuclear chemistry, 181(2), 1994, pp. 363-371
Instrumental activation analysis (INAA) based on irradiations in a nuc
lear reactor with particularly high relative fluxes of resonance and f
ast neutrons has been shown to open new possibilities for multi-elemen
t surveys of mosses used as monitors of atmospheric deposition. Compar
ison is made with data obtained by inductively coupled plasma-mass spe
ctrometry (ICP-MS) and conventional INAA. Data for 15 elements not pre
viously investigated in routine moss studies are presented, e.g.,Zr, S
n, I-if, Ta, W, Au, Th, and the rare earth elements Ce, Nd, Eu, Gd, Tb
, Tm, Yb, Lu. Other elements particularly well determined by this appr
oach are Sc, Co, As, Ag, Sb, Cs, La, Sm, Th, and the non-metallic trac
e elements Se, Br, and I. Advantages and drawbacks with the high fast
neutron component are discussed.
