Summary:A complete sequence of daily rainfall (bulk precipitation) samples collected between January 1980 and April 1981 at Wallingford, in central Southern England, together with a few month's samples from other sites in west Wales, northern England and southern Scotland, have been analysed for iodate and total iodine concentration. The wet deposition of iodine depended mainly upon the amount of rainfall, and the average monthly total iodine concentration was nnt found to vary seasonally as had been anticipated. This behaviour contrasted markedly with that of chloride and sodium ions, whose average monthly concentration decreased during summertime. On average, iodate composed one-half of the total iodine. The iodine chemistry of the rainfall is discussed in terms of the equilibrium between HOI and I2, and between iodine and other redox systems, e.g. peroxide and ozone.
