This will lead to an increase in the level of reactive metabolites and result in an increased reaction of these metabolites with intracellular macromolecules.

The EPA diffusion calculation when so normalized leads to a concentration averaged over all persons within 5 miles of a PVC plant and averaged, over a year's-time is less-.than 1 part inX billion given an average risk,, on'the EPA*s linear basis of S x 10--8 /year averaged over the 5 million people who reside within % 5 miles of PVC plants in.the U.S.

However, possible uses of PCBs in painls, varnishes, waxes, synthetic polymers, inks, dust-inhibitors, and pesticide formulations may lead to direct contamination of natutal unlers through industrial and sanitary waste dischargers.

The study concluded that asbestos may cause about 5% of all present day lung cancer.12 Inasmuch as lung cancer constitutes about 20% of all cancer, this suggests that asbestos caused lung cancer accounts for about 1% of all cancers---a finding which tends to support most of the estimates shown in Table 11. f Author example, in 1976 a group of government investigators reported on the effects of very low human exposures t o asbestiform fi bers among workers at a gold mine at Lead, Si) 1:1 They re ported a threefold excess in respiratory cancer and suggested that this was due to very low fiber exposures.

Hence, the alkylation that produces imidazo-derivative formation (with DNA) labilizes the purine 6-glycoside linkage, which leads to depurination.
