The aim of this study was to determine selenium content in selected tissues of roe deer (Capreolus capreolus) from Wielkopolska region and soil collected from the area of roe deer living. Research material included liver and kidney samples obtained from 23 roe deer (Capreolus capreolus). Animals were shot during the hunting season in summer 2009 in compliance with the hunting limits set. Soil samples (0–20 cm) were taken from 18 sampling sites in 2009. Selenium concentration in samples was determined spectrofluorimetrically using 2,3-diaminonaphtalene (DAN). Selenium concentration in soil ranged from 0.00–0.57 µg · g^–1 d.m. average 0.19±0.11 µg · g^–1 d.m. The mean Se content in livers and kidneys was 0.06 µg · g^–1 w.w. and 0,33 µg·g^–1 w.w., respectively. We observed positive statistically significant correlation (r = 0.7583; P = 0.00003) between these organs. Low selenium concentration in roe deer tissues and in soil indicates that examined area is deficient in selenium.
