Abstract

Atmospheric methyl iodide (CHI) has been measured at a ground-based site in eastern England for two consecutive summers. Maximum values of 43.1 pptv and 28.9 pptv were recorded in 1989 and 1990, respectively. CHI was not detectable in the autumn and winter months. Episodes of elevated concentrations persisted for periods ranging from a few hours to several days. The origin of much of the observed CHI would appear to be the Atlantic Ocean, indicating the presence of large source areas, possibly phytoplankton blooms, in ocean waters. Estimates are made of the dry deposition velocity of CHI, and the potential impact of elevated tropospheric levels on the human uptake of iodine.
