Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 6,   Pages 867-874 doi: 10.1007/s11783-013-0541-0

Abstract: dioxide (SO ) emission is decomposed into three parts: source prevention, process control and end-of-pipethat from 2001 to 2010 the reduction of SO emission density in China was mainly contributed by end-of-pipeHowever, given its initial effort, the effect is limited compared with that of the end-of-pipe treatmentThis implies that environmental regulation and technology promote process control and end-of-pipe treatment
