Description	The aim of this study was to evaluate arsenic content in the soils of the Bohemian Forest (Šumava Mts.) region. Geogenic and anthropogenic factors of arsenic inputs into the soils were assessed. Arsenic concentration (2M HNO3 and aqua regia extract) was determined in 221 soil samples collected in three Bohemian Forest districts (Klatovy, Prachatice, and Český Krumlov). More detailed results about the arsenic occurrence in soil samples were provided using various methods including assessment of arsenic distribution in soil profile, the sequential extraction procedure results or arsenic concentration in plants. Arsenic concentration ranged from 2.1 to 183 mg.kg–1 in the non-forest soils of the region and followed an approximately lognormal distribution. Geometric mean concentration of aqua-regia-extractable arsenic is 10.9 mg.kg–1. The results confirmed geogenic source of arsenic load in soils of the region, however, effects of anthropogenic factors could be raised in some parts of the region, especially because of the historical gold mining activities or urbanization factors. There was observed increased arsenic concentration in the zone stretched from Horská Kvilda to Velhartice inclusive primary gold deposits.
