chlorine dioxide (an explosive gas (ClO2) used chiefly in bleaching paper or starch or soap or flour and in water purification)
sulfur dioxide; sulphur dioxide (a colorless toxic gas (SO2) that occurs in the gases from volcanoes; used in many manufacturing processes and present in industrial emissions; causes acid rain)
Context examples:
