Zusammenfassung:	A method for reducing hydrogen sulfide emissions from heavy fuel oil or an asphalt composition comprising admixing an additive with a heavy fuel oil or asphalt composition wherein the additive comprises a solution or dispersion of bismuth component is selected from the group consisting of Bi boroacylates, Bi carboxylates, and Bi oxides, and combinations thereof. Procédé de réduction des émissions de sulfure dhydrogène provenant du mazout lourd ou dune composition dasphalte. Le procédé consiste à adjuvanter un additif au mazout lourd ou à la composition dasphalte, ledit additif comprenant une solution ou une dispersion dun composant de bismuth choisi parmi le groupe constitué des boroacylates de Bi, des carboxylates de Bi et des oxydes de Bi, de même de que toute combinaison connexe.
