The International Agency for Research on Cancer ('IARC') assessed the carcinogenicity of "mineral oils" in 1983 and 1987 and concluded that there is sufficient evidence from studies in humans that mineral oils (containing various additives and impurities) that have been used in occupations such as mulespinning, metal machining and jute processing are carcinogenic to humans.
Mednarodna agencija za raziskovanje raka (IARC) je leta 1983 in 1987 ocenila rakotvornost „mineralnih olj“ in prišla do zaključka, da iz študij, ki so proučevale učinke na ljudi, izhaja dovolj dokazov, ki kažejo, da so mineralna olja (ki vsebujejo različne dodatke in nečistoče), uporabljena pri poklicih, kot so predenje bombaža, strojno obdelovanje kovin in predelovanje jute, rakotvorna za ljudi.
