In 1973, French toxicologist and research director Henri Pézerat identified asbestos in white dust falling from the ceiling of his chemistry laboratory at Paris’s Jussieu Campus. After reviewing evidence that the silicate was carcinogenic, he reported the danger to an inter-union workplace-safety collective. His intervention connected laboratory findings with the occupational exposure experienced by workers who had little control over hazardous industrial conditions.
Pézerat supported workers at the Amisol asbestos factory in Clermont-Ferrand in 1978 and later helped lead the Anti-Asbestos Committee Jussieu and Ban Asbestos France. The campaign contributed to France’s ban on asbestos in 1997, although the source does not provide casualty totals, financial damages, or details of specific enforcement proceedings. After retiring, Pézerat continued campaigning against carcinogenic pollutants, including asbestos-removal work on the aircraft carrier Clemenceau. His career illustrates how whistleblowing and worker organizing challenged official and industrial tolerance of a known occupational carcinogen.
