These are mixtures of compounds containing differing numbers of chlorine atoms per molecule. The mixtures included this category are PCB-1016, 1221, 1232, 1242, 1248, 1254, and 1260. The last two digits refer to the degree of chlorina-tion: thus, PCB-1016 contains 16%chlorine and PCB-1260 contains 60% chlorine. These designations correspond to the Monsanto designations Aroclor 1016, etc. (“Aroclor” is frequently misspelled as “Arochlor”). Aroclors 5432, 5442, and 5460 are polychlorinated terphenyls. PCBs are marketed in Japan as Kanechlors and in France as Prodelecs.
