【 摘 要 】

Incidental ingestion of contaminated soils isa major route of Pb uptake by humans, especially by children. Lead speciationin soils controls its bioavailability. Bioavailability assessment requires thedetermination of the amount of absorbed lead if a contaminated soil is ingested.In vivo tests, which employ animals, are considered the best model toinfer absorption of Pb. But they have some logistic limitations and severalauthors proposed in vitro methods, which simulate conditions of humandigestion. Many of them present results which correlate with in vivoessays. Several authors consider in vitro tests a good and reliable alternativeto infer lead bioavailability.
