First, those studies were conducted in areas with a high concentration of workers exposed to asbestos in shipbuilding and railroad equipment manufacturing (52, 66) or to multiple carcinogens in foundries and the chemical and metal industries (69, 70).
There are several sectors where there was exposure to multiple carcinogens, both in manufacturing and in other sectors.
Children around the world, including children in Latin America are at risk of exposure to multiple carcinogens in air, water, food, and soil.
Multistage models have been used to describe various features of the incidence of cancer including the shape of the age-incidence curve; the influence of age at, duration of, and time since exposure; and the synergistic effect of exposure to multiple carcinogens.
Where exposure to multiple carcinogens remained, it was assumed that the exposures were independent of one another and that their joint carcinogenic effects were multiplicative.
Contrary to the myth that only tobacco smoke contains harmful substances, analyses of marijuana smoke reveals multiple carcinogens.
More detailed results for industry sectors highlighting the important ones defined by large numbers, multiple carcinogens and/or cancer sites are given in a separate paper in this supplement.
Several industrial sectors have been highlighted where many workers were exposed potentially to multiple carcinogens.
The study has highlighted several industrial sectors with large proportions of workers potentially exposed to multiple carcinogens.
By omitting naphthalene from its cancer risk assessment, the FDA ignored the potential cumulative effect of exposures to multiple carcinogens.
Results demonstrate that cumulative exposures to multiple environmental carcinogens and neurotoxins can be comparatively high for children from a poor inner-city neighborhood.
