Abstract:Analysis of a sample of MILORGANITE® fertilizer which had been sealed in glass for exhibition in 1933 shows a broad range of chlorodibenzo-p-dioxins remarkably similar to that of more recent material. It is speculated that the compounds were formed mainly by condensation reactions after chlorination of phenolic substances in the water supply and wastes.
