摘　　要：世界范围内燃煤而释放的二氧化硫气体和颗粒物,严重地扰动了硫的全球环境地球化学循环,是导致全球性大气污染和酸沉降的重要原因.为定量地评估人为活动释放硫和天然生物成因硫对全球环境质量的相对影响,稳定硫同位素示踪技术是一新的发展方向.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.
