The possible mutagenic effect of the occupation of TV announcer

In a group of TV announcers, a significant increase in the number of classical aberrations was detected in peripheral blood: 7.5 +/- 3.477% in comparison with 3 control groups (A - 7 healthy women matched for sex, age and place of residence, B - 9 members of TV technical staff, C - 9 actors and actresses) with a mean aberration level of 2.96 +/- 1.136. SCE numbers were not increased in the TV announcers compared to controls. An increased frequency of reproduction failure has also been noticed in TV announcers (females). A decrease in the level of aberrant cells was noticed when the announcer had been on holiday, although this was not statistically significant. The possible mutagens in the working environment of TV announcers are discussed; there is a suspicion that azodyes, present in cosmetics or other chemicals, may be the mutagenic factor.
