已经对火山喷发向对流层和平流层排放的氯化氢、氟化氢和二氧化硫的年排放量进行了估算。估计向对流层的年排放速率分别为7.5×10⁵、3.8×10⁴和7.5×10⁶公吨，向平流层的年排放速率分别为2.8×10⁴、1.4×10³和2.8×10⁵公吨。结果表明，除了在非常强烈的火山活动之后的短时间内，人为产生的氯氟烃在平流层化学中可能比火山喷发产生的卤化物发挥更大的作用。
Estimates have been made of the annual emissions of HCl, HF, and SO2 to the troposphere and stratosphere from volcanic eruptions. The estimated annual emission rates to the troposphere are 7.5×105, 3.8×104, and 7.5×106 metric tons, respectively, and those to the stratosphere are 2.8×104, 1.4×103, and 2.8×105, respectively. The results demonstrate that anthropogenic chlorofluorocarbons have the potential to play a much greater role in stratospheric chemistry than the halides from volcanic eruptions do except possibly for short periods following very intense volcanic activity.
