Watson, A P

Food-chain transport of Pb-210 and Po-210 from soil to edible plant parts and from animal feed to meat and milk was evaluated from a review of literature. The degree of transfer was characterized by estimating concentration factors as well as the transfer coefficients B/sub v/, B/sub r/, f/sub m/, and f/sub f/. Global dietary intake of Pb-210 and Po-210 was also summarized, and 50-y dose estimates to target organs were calculated. The greatest estimated ingestion doses were those to populations with large dietary complements of animal protein in the form of seafood (Japan) or caribou/reindeer muscle and organ meats (Arctic Eskimos and Lapps). The origin and magnitude of inhalation exposure and dose from tobacco products were also assessed. For the majority of internal organs evaluated, the dose resulting from smoking commercially available tobacco products is comparable with or greater than the dose estimates for ingestion of naturally occurring dietary Pb-210 and Po-210. 79 refs.
