Indeno[1,2,3-cd]pyrene (IP) is a major environmental pollutant which is carcinogenic on mouse skin and in rat lung. Unlike benzo(a)pyrene, IP is a nonalternant polycyclic aromatic hydrocarbon which is devoid of a bay region. IP was mutagenic in Salmonella typhimurium TA100 in the presence of a 9000 X g supernatant from the livers of Aroclor-pretreated rats. Using a similar activation system, th...
