On July 10, 1976, a cloud of vaporized products containing dioxin escaped from a deposit of a plant of the Icmesa firm in the northern suburbs of Milan. The fallout was deposited on a vast zone in the municipalities of Desio, Seveso, Meda, and Cesano. Dioxin was not the desired product of the industrial process, but rather an impurity which generally accompanies trichlorophenol, and, to a smaller extent, the products synthesized from trichlorophenol. Among these there are hexachlorophene and the herbicide 2,4,5-trichlorophenoxyacetic acid, which was used as a defoliant in the Vietnam War. After describing toxicological properties of dioxin, this paper examines the role of multinational corporations and of capitalist governments in exploiting not only the people of underdeveloped lands, but also workers of developed countries, transforming into capital not only the increased value of man, but also the conditions, harmfulness, and risks of work.
