【Abstract】 Burning coal results in anthropogenic emission of two kinds of pollutants with different isotopic composition. The released sulfur dioxide is always enriched in lighter sulfuric isotope relative to corresponding coal, the particles released are always enriched in heavier sulfur isotope. Implication of this phenomenon in environmental geochemistry was discussed.更多还原
