2026-08-31 Analysis of Heavy Metal Sources and Evaluation of Accumulation in Agricultural Soils in the Black Soil Area of Baicheng City doi:10.57760/sciencedb.iga.0019o en This study analyzed the spatial distribution, sources, accumulation, and ecological risks of seven heavy metals in 111 agricultural topsoil samples from the black soil area of Baicheng City. Zn, Ni, and Pb were mainly derived from natural sources; Cu and Cr were primarily influenced by agricultural activities; and As was associated with industrial activities such as mining and coal combustion. Overall ecological risk was low, although Cd was identified as the primary risk factor.
