Sulfur dioxide
Sulfur dioxide (also sulphur dioxide) is the chemical compound with the formula SO
2. It is a toxic gas with a pungent, irritating smell. It is released naturally by volcanic activity and is produced as a by-product of the burning of fossil fuels contaminated with sulfur compounds.

Carbon dioxide and sulphur dioxide concentrations have been measured on a transect between urban Nottingham and a rural area 15 km to the south-west. In Part I, the results of fixed point measurements at the ends of the transect are described. Seasonal averages showed no significant difference for CO2 or SO2 concentrations in the summer; in winter the mean CO2 concentration in the city centre was 5 μl ℓ−1 larger than the rural mean. These figures conceal large differences in the diurnal variation between the two sites.
