## Abstract Trace atmospheric gases have been sampled using potassium‐iodide‐based reactant traps for ozone removal. GC‐MS analysis revealed the presence of organic iodine compounds which were present neither in the atmosphere nor as contaminants of the materials used, but more likely arose from re
