“…Unusual behaviors have also been reported, e.g., slight enrichment of Ca (Ondov et al, 1979a), slight enrichment of Fe (Smith et al, 1979a), no change with Zn and Ga (Gladney et al, 19761, enrichment of Ti (Ondov et al, 1979b), depletion of Fe and of Ce relative to A1 (Gladney et al, 1976), etc. These observations and the conflicting reports for group 111 elements may be the effect of coal type, different operating parameters (such as combustion temperature), and inaccuracies involved in sampling and analytical procedures.…”

“…The magnitude of global coal-derived beryllium is not well known, ranging from 0.1 to 1,000 mg/kg Be, and oil typically contains 0.08 mg/kg (Bowen, 1966;Gluskoter et al, 1977;Heindl, 1970;Ruch et al, 1974). The elemental composition of coal burned at two western US power stations is given by Ondov et al(1979), showed that the ratio of Be/Al for the selected coal was between 4.07 and 5.28 x10 -5 , not dissimilar to the ratio for soil in the US (5.90 x10 -5 , Smith et al, 2005). However, it appears that much of the beryllium in the fuel is associated with organic material and emitted as particulates (Tepper and VanOrdstrand, 1972) rather than the alumino-silicate fractions.…”

“…Des relations empiriques décrivant l'enrichissement E ij cv (D) des métaux lourds As, Cd, Cr, Cu, Ni, Pb, V et Zn en fonction du diamètre aérodynamique des particules ont été déterminées à partir d'une analyse statistique des données expérimentales publiées dans la littérature [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Les valeurs expéri-mentales des concentrations en métaux lourds des poussières déterminées en fonction du diamètre D des particules ont été ajustées au moyen d'une ana- Les barres d'erreur reflètent la dispersion des points expérimentaux issus de campagnes de mesures ne précisant pas la concentration de métal lourd dans le charbon ou le taux de cendres du charbon [3,5,12].…”
