The present invention provides compositions including a salt selected from the group consisting essentially of sodium nitrate, sodium nitrite, ammonium nitrate, lithium nitrate, barium nitrate, cerium nitrate, and mixtures thereof, as flue gas conditioning formulations for use in controlling particulates, hazardous substances, NO.sub.x, and SO.sub.x. For the purpose of obtaining greater yields of particulate and hazardous substance removal, the compositions may further include a polyhydroxy compound, preferably selected from the group consisting essentially of sucrose, fructose, glucose, glycerol, and mixtures thereof. Methods are also provided for adding these compositions to the flue gas stream to control particulate, hazardous substance, NO.sub.x, and SO.sub.x emissions.

[ What is claimed is:] [1.] A compostion for use with an emission control device to remove particulates and hazardous substances from a flue gas stream, said composition located at a point upstream of said emission control device and comprising a salt selected from the group consisting essentially of sodium nitrate, sodium nitrite, ammonium nitrate, lithium nitrate, and mixtures thereof, provided that the composition does not comprise ammonium nitrate and sodium nitrite at the same time. [37.] A method for removing particulates and hazardous substances from a flue gas stream, comprising adding a composition to the flue gas stream at a point upstream of an emission control device, wherein the composition is selected from an aqueous solution and a dry powder and comprises a salt selected from the group consisting essentially of sodium nitrate, sodium nitrite, ammonium nitrate, lithium nitrate, and mixtures thereof, provided that the composition does not comprise ammonium nitrate and sodium nitrite at the same time.
