The rate of atmospheric oxidation of sulphur dioxide varies from less than 1% per hour to around 12% per hour, depending upon atmospheric conditions. As a consequence of this slow conversion rate, the SO2 emitted can influence the acidity of precipitation at other locations far removed from the point of emission.  2, record 3, English, - transformation%20rate
