An apparatus for sampling and trapping the air in potato stores was developed and used to study the accumulation of volatile substances in a modern large store over a season. Isopropyl‐N‐(3‐chlorophenyl) carbamate (CIPC, chlorpropham), together with two isomers of tetrachlorobenzene, was present at all times after its application as a sprout suppressant, although the concentration fell with time. None of the known volatile substances associated with potatoes nor metabolites of isopropyl‐N‐(3‐chlorophenyl) carbamate was detected. 2,3,4,6‐Tetrachloroanisole and pentachloroanisole were present at all times even before the store was filled, but did not reach levels at which taint occurred in the processed products. Eight commercial samples of isopropyl‐N‐(3‐chlorophenyl) carbamate were analysed and the only major variation found was the presence of isopropyl‐N‐phenyl carbamate (IPC, propham) in two formulations.
