Abstract
Substances which are commonly sucked or chewed in two areas where the incidence of oesophageal cancer is high, the Transkei and north-east Iran, were tested in bacterial mutagenicity assays. Pyrolysed substances, opium dross in north-east Iran and tobacco pipe residues in the Transkei, displayed mutagenic activity in Salmonella typhimurium strains TA98 and TA100 in the presence of rat liver microsomes.Entities:
