The human selenium status in 10 locations of Irkutsk region (n = 216) is estimated using serum and hair selenium as biological markers. Extremely low serum selenium was typical for the inhabitants of Angara area (63-84 mcg/l). Hair selenium varied from 504 mcg/kg to 718 mcg/kg, the lowest values being found in Shelehov and Angarsk, the highest--in Karam and Mama. Low selenium concentrations were found also in the main food products: cereals--49-89 mcg/kg, meat--234-489 mcg/kg of dry weight, bread--106-180 mcg/kg of dry weight.

Low levels of essential mineral elements such as cobalt, copper, and iron, in organisms reduce immune function, increasing the chances of parasitic infection. This phenomenon has been demonstrated widely in domestic animals but rarely in wildlife. In this study, we used data from 7- to 9-month-old roe deer (), living in two different populations facing contrasting environmental conditions (Trois-Fontaines and Chizé), to investigate whether the parasitic and immunological statuses could be related to essential element status.
