Abstract: Targeting the selenium resource in soils of Luoyang City, Henan Province, this study analyzed the distribution of total selenium concentration under different geological settings, soil types, land use types, acidity and alkalinity, and organic matter. Furthermore, it determined the bioavailability and speciation distribution of selenium in the soils. The results indicate that: (1) The soils in Luoyang City have total selenium concentrations of (0.03~5.67)×10^-6, with an average of 0.30×10^-6, and the area of soils with moderate and rich selenium accounts for 94.73%; (2) The average selenium concentration is the highest in soils of the Jixian Yunmengshan formation and the lowest in soils of the Cambrian Xinji Formation; (3) The average total selenium concentration is the highest in lime concretion black soil and the lowest in paddy soil; (4) Regarding land use types, the average total selenium concentration is relatively high in soils of paddy land and woodland; (5) Soils with high acidity and high organic matter concentrations are favorable for selenium enrichment; (6) In terms of soil types, the average concentration of bioavailable selenium is the highest in fluvo-aquic soils and the lowest in red clays; (7) The average concentration of bioavailable selenium is higher in alkaline soils than in neutral and acidic soils; (8) Selenium in soils primarily occurs in residue, strong organic bound, and humic acidic bound forms, with the highest average concentration of bioavailable selenium occurring in alkaline soils and red clays. The selenium resource in the soils in Luoyang City has high utilization potential, and it is feasible to conduct targeted development and planning of the selenium-rich industry according to the distribution of total selenium concentration in the study area.
