Describe the major pathways and transformations involved in the atmospheric transport of Sulphur, produced as SO2 in combustion processes. Outline the major impacts of SO2 upon plants. Sulphur is an essential nutrient for normal plant growth and development. The primary source of Sulphur is from the soil in the form of sulphate (SO42-), which is taken up by the roots and translocated to the leaves where most of it is reduced and assimilated into organic sulphur compounds. An important primary source of sulphur can be found in the atmosphere. 15 molecular species of Sulphur are found in the atmosphere, according to Berresheim et al (1995). Plants unable to acquire all the sulphur they need from the soil are able to use SO2 from the atmosphere or other volatile compounds such as H2S.When more SO2 is taken up from the atmosphere by plants then is needed, plants are adversely effected. SO2 is...
