Abstract

Evaluated has been bioconcentration potential by fungi and risk to human consumers from exposure to natural long-lived radioactive uranium (234U, 238U) and thorium (230Th, 232Th) sequestered in stems, caps and the whole fruiting bodies by mushrooms of the genus Leccinum and Leccinellum. Edible species in the study were collected from boreal forests in the northern regions of Poland and investigated: red-capped scaber (Leccinum aurantiacum), orange oak bolete (Leccinum aurantiacum var. quercinum), foxy bolete (Leccinum vulpinum), slate bolete (Leccinum aurantiacum var. duriusculum) and hazel bolete (Leccinellum pseudoscabrum). The study showed the species accumulated uranium (234U, 238U) and thorium (230Th, 232Th) form soil to some degree but the calculated values of the bioconcentration factor were below 1. The evaluation showed that Leccinum and Leccinellum mushrooms can contribute to annual effective radiation dose maximally at about 0.9 μSv. Hence, consumption of these mushrooms might increase the annual effective ionizing radiation dose received by a human, while the exposure is considered low from the toxicological point of view even if eaten at elevated amounts.
